1 INTRODUCTION

The objective of this Monitoring Report is to show the calculation of the emission reductions

achieved by the project activity under the Voluntary Market and verified by a Designated

Operational Entity.

The monitoring period is from 20/11/2007 to 4/05/2008 (both days included).

The report also shows the Monitoring and Verification Plan for data collection and auditing

followed by the project developer in order to determine real and credible emission reductions.

2 REFERENCE

The monitoring plan is in accordance with the registered project design document of

Petrotemex Energy Integration Project, Version 10 of 08/02/20081, that uses existing baseline

and monitoring methodologies (AM0018/Version01.1 of 06/12/2004 and

ACM0004/Version02 of 03/03/2006), which have been approved and made publicly available

by the CDM Executive Board. The methodologies are designated “Methodology for steam

optimization systems” and “Consolidated methodology for waste gas and/or heat and/or

pressure for power generation”.

According to the methodology ACM0004/Version02, the emission factor of the grid is

determined using the methodology ACM0002/Version06 of 19/05/2006.

3 GENERAL DESCRIPTION OF THE PROJECT ACTIVITY

3.1 OBJECTIVES OF THE PROJECT

The project activity aims at reducing GHG emissions (mainly carbon dioxide and, to a lesser

extent, methane and nitrous oxide) through the implementation of a series of mitigation

measures that involve fuel and electricity savings as well as the installation of new electricity

self-generation equipment.

These goals will be achieved through a process of energy integration, leading to lower

consumption of steam from boilers and lower electricity demand to the national grid, thus

reducing overall fuel usage. Besides, additional power will be generated using remaining low-

quality steam produced from waste heat of the production process.

Petrotemex will lead this project activity that involves its production plants of Pure

Terephthalic Acid (PTA), located at Cosoleacaque and Altamira, in Mexico.

Petrotemex is a business of Alpek Group, subsidiary of Alfa, oriented to the production of

raw materials for polyester yarn, Polyethylene terephthalate (PET) and other products.

The project activity generates the inherent benefits of fuel and electricity savings, and clean

self-generation:

� Petrotemex technical staff has carried out studies in order to design the best option for

energy saving for each plant, which involves adaptation and transference of efficient

and clean technology to the productive sector.

� As a result of the project activity, there is an improvement in plant efficiency in a

thermodynamic sense, reducing fuel burning at the plant site, and reducing electricity

purchases, thus decreasing electricity generation outside the industrial facility.

� The energy savings obtained through the project activity contributes to the sustainable

use of natural resources, and to improve the environment by reducing emission of

pollutants and particulate matter in the air.

� The project activity generates economic benefits related to CDM and Voluntary

Market revenues. The benefit obtained by selling CERs and VERs will allow

Petrotemex to invest in further research and development and to cover part of the

initial investment and the unexpected costs of project implementation and operation.

� The project activity improves de air quality and the cleanliness of the work site, thus,

improving the labor and health conditions of the employees.

� The project activity provides job opportunities during the construction phase of the

project. About 100 new work positions are needed during this phase.

Thus, the project activity involves social, environmental, and economic benefits, contributing

to the sustainable development objectives of Mexican Federal and State authorities, in

accordance with the development plans of:

� Mexico (Plan Nacional de Desarrollo 2001-20062),

� Veracruz State (Plan Veracruzano de Desarrollo 2005-20103), and

� Tamaulipas State (Plan Estatal de Desarrollo 2005- 20104).

The project proponent has obtained the written approval of the Mexican DNA, confirming

that the project supports sustainable development.

3.3 TECHNICAL DESCRIPTION OF THE PROJECT

The project activity involves the two PTA production plants of Petrotemex, one located in

Cosoleacaque and the other one in Altamira.

Cosoleacaque Plant

The project activity involves the reduction of overheated steam generation in boilers by

switching from the existing turbo-compressors to a new high-efficiency turbo-compressor.

The new turbine of such compressor will utilize surplus low-pressure steam from PTA

production process, instead of the overheated steam used by the existing compressors.

The project also involves the reduction of low-pressure steam consumption from the PTA

production process by increasing of low-pressure steam generation using waste heat from

such process. In order to achieve that, the following mitigation measures were carried out:

• Switching from binary distillation to azeotropic distillation in dehydration columns.

• Incorporation of a new process of thermo-compression of the steam used in the

reboiler of the dehydration tower.

• Switching the current dehydration columns’ condensers to new condensers that

generate low-pressure steam.

• Installation of new systems generating low-pressure steam using the heat released by

the oxidation reaction of p-xylene.

In addition, steam consumption is reduced by shutting down the low-pressure steam turbine

connected to turbo-compressor.

Due to the availability of the low-pressure steam flows mentioned above, the generated

energy surpasses the requirements of the new turbo-compressor. Thus, the project also

involves the installation of an electricity generator integrated to the new compression train to

obtain the complete use of energy.

Additionally, the project activity also involves changes in electricity consumption due to the

shutting down of the condenser fans of the dehydration towers, the moto-compressor, among

other equipment, and the installation of more-efficient new equipment like motors and pumps

(actually, there are electricity savings due to the project activity, but they are not considered

in the calculation of emission reductions as a conservative assumption).

Altamira Plant

The project activity involves the reduction of low-pressure steam consumption used as means

of heating the reboilers in dehydration column, by switching from binary to azeotropic

distillation. The more-efficient low- pressure steam generated by azeotropic distillation will

be used to generate electricity in a new turbo-generator, in order to obtain the complete use of

energy resulting from the availability of low-pressure steam flow mentioned above.

The project activity also involves taking advantage of the additional energy benefits obtained

when expanding plant capacity to 900,000 tPTA/year in 2007, generating more steam that can

be used in the turbo-generator to produce additional power output. The proposed project

activity already considers such an expansion so as to capture these future benefits with no

additional investment.

4 PROJECT LOCATION

The project activity was implemented at the production facilities of Petrotemex, located in

Cosoleacaque and Altamira, in the States of Veracruz and Tamaulipas, respectively.

The exact coordinates of the project sites are 18° 1’ 56” North and 94° 35’ 43” West for

Cosoleacaque plant, and 22° 22’ 44’’ North and 97° 53’ 32’’ West for Altamira plant.

5 CURRENT STATUS OF THE PROJECT

In Cosoleacaque plant, the project activity started operating in the lately months of 2005 and

reach its stable operation on March 2006, while in Altamira plant, the project activity started

operating on January 2008.

The Petrotemex Energy Integration Project started operating in the lately months of 2005. A

first VER verification was done on 19/11/2007 under the VSC version 1.

The first voluntary crediting period started on 01/11/2005.

The CERs generation began on 05/05/2008, when the project was registered as a CDM

project activity.

6 MONITORING PLAN

6.1 DATA MONITORED

Since the monitoring plan of the proposed CDM project was not completely implemented

until the project was registered as CDM, the data used to determine the emission reductions

obtained from 20/11/2007 to 4/5/2008 was collected by Petrotemex’ staff following a

monitoring plan with some differences, comparing to the requirement of the methodologies

applied to the CDM project. In order to explain these minor differences, the registered

monitoring plan and the monitoring plan used in this monitoring period are shown in the

following tables.

regulations.

As part of the routine of Petrotemex, perimeter noise measurements and medical

examinations to all the personnel are carried out in Cosoleacaque and Altamira plants.

In Altamira plant, the perimeter noise is monitored in an annual basis and control measures

are established in accordance with the results. Complete medical examinations of the

personnel are carried out on an annual basis, including the administrative personnel.

Additionally, the Altamira plant has a continue communication with the local community,

through meetings that are included within the annual training program for the community

schools about preventing contamination. Mini-Olympics activities are included as a part of

this activity and, through answer addressing exercises, Altamira plant can get close to the

authorities and organize meetings with them.

In Cosoleacaque plant, the medical examinations (clinical analysis, radiographies, ocular

analysis, and audiometry) are carried out annually to all the personnel, and the perimeter noise

is monitored according to the Mexican norms.

All the monitored data, including data related to sustainability indicators, will be registered

and stored according to the procedures developed by the company.

Additionally, all the data monitored will be filed until two years after finishing the crediting

period.

implemented in Cosoleacaque and Altamira plants, because despite the project is an innovate

technological development, the equipment, recipients and instruments are of the same type

than those currently installed in the plants.

Petrotemex developed a specific Calibration Program for the equipment that is involved in the

CDM project. The maintenance management is in charge of the follow up of this program

through instruments department.

their requirements, as well as, to assure that the calibration of the instrument is within the rank

of exactitude specified by the manufacturer.

6.7 MAINTENANCE PROCEDURES

implemented in Cosoleacaque and Altamira plants, because despite the project is an innovate

technological development, the equipment, recipients and instruments are of the same type

than those currently installed in the plants.

These procedures were available during the verification.

6.8 SPREADSHEET MODELS

For this project, the monitoring methodology is applied through spreadsheet models. The

spreadsheets automatically provide the total GHG emission reductions achieved through the

project.

• Result Fields: Green fields display key result lines as calculated by the model.

7 ENVIRONMENTAL IMPACT

The activities involved in this energy integration project have positive environmental impacts

on several grounds.

As a consequence of steam saving, the project activity will reduce emissions of particulate

matter and pollutant gases like SO2 and NOx from combustion of petroleum fuels in boilers,

reducing local negative environmental impact and improving air quality in the regions.

In addition, by reducing electricity demand from the Electricity Federal Commission

(Commission Federal de Electricidad – CFE), the project will reduce emissions from

electricity generation of the power plants connected to the grid. Thus there will be a reduction

of the local negative effects of such emissions.

In the case of this project activity, it is not necessary to modify the environmental impact

study required by the Environmental and Natural Resources Secretariat of Mexico, due to the

modifications that will be carried out by Petrotemex will not change the PTA production

process.

In addition, it is considered that the construction process will not have any negative

environmental impact.

8 EQUATIONS USED FOR CALCULATION OF EMISSION REDUCTIONS

Baseline emissions BEEG related to

avoided grid electricity generation due to

the waste heat recovery for power self-

generation in Cosoleacaque and Altamira

plants

BEEG = EG × EFgrid

where

EG Net quantity of electricity generated (MWh/year). It is

obtaining by subtracting the quantity of electricity

required by the power generation equipment to the

total electricity generation.

EFgrid CO2 baseline emission factor for the electricity

displaced due to the project activity (tCO2/MWh). It

is determined using the methodology

ACM0002/Version06 as a combined margin emission

factor, consisting of the combination of the operating

margin and the build margin factors. It is calculated

ex-ante and considered fixed along the crediting

period.

CO2 baseline emission factor for the

electricity displaced due to the project

activity

EFgrid = wOM × EFOM + wBM × EFBM

where

EFOM Operating margin emission factor (tCO2/MWh).

EFBM Build margin emission factor (tCO2/MWh).

wOM and

wBM

Relative weights assumed to be equal to 0.5,

according to the default value provided by the

methodology ACM0002/Version06.

Page 20: Petrotemex Energy Integration Project Grupo … · 6.2 QUALITY CONTROL ... Petrotemex Energy Integration Project, ... this project activity that involves its production plants of

MONITORING REPORT

Petrotemex Energy Integration Project

20

Operating margin emission factor EFOM = (Σkp Fkp × COEFkp) / (Σp GENp)

where the sum over k extends to all the fuels used by the power sources p, and the sum over p extends to all power sources

delivering electricity to the grid, not including low-operating cost

and must-run power plants, and including imports to the grid, and:

Fkp Quantity of fuel k consumed by the power source p

(TJ).

COEFkp CO2 emission coefficient of fuel k (tCO2 /TJ).

GENp Electricity generation delivered to the grid by the

power source p (MWh).

CO2 emission coefficient of fuel k COEFkp = CEFk × OXIDk

where

CEFk Carbon dioxide emission factor per unit energy of

fuel k (tCO2/TJ). IPCC default values are used.

OXIDk Oxidation factor of fuel k. IPCC default values are

used.

Build margin emission factor EFBM EFBM = (Σkq Fkq × COEFkq) / (Σq GENq)

where the sum over k extends to all the fuels used by the power

sources q, and:

Fkq Quantity of fuel k consumed by the power source q

(TJ).

COEFkq CO2 emission coefficient of fuel k (tCO2 /TJ). It is

obtained through equation showed above.

GENq Electricity generation delivered to the grid by the

power source q (MWh).

Project emissions PEEG and leakage

LEEG related to avoided grid electricity

generation due to the waste heat

recovery for power self-generation in

Cosoleacaque and Altamira plants

According to the methodology ACM0004/Version02, no leakage is

considered. In addition, no project emissions are considered, since

there are not fuels fired in the project scenario for electricity

generation start-up, in emergencies, or to provide additional heat

gain. Thus, PEEG = 0 and LEEG = 0.

Emission reductions EREG related to

avoided grid electricity generation due to the waste heat recovery for power self-

generation in Cosoleacaque and Altamira

plants

EREG = BEEG – PEEG – LEEG = BEEG

Emission reductions ERFS related to

boiler steam optimization

ERFS = Σ Cernet = Σ [Cer – (Cer1 + Cer2)] = Σ Cer

where the sum extends to all the days in a given year, and

Cernet Emission reductions per day (tCO2e/day).

Cer Emission reductions per day related to fuel savings due

to the boiler steam optimization in Casoleacaque plant

(tCO2e/day).

Cer1 Emissions related to captive generation (tCO2e/day).

Cer2 Emissions related to external grid supply (tCO2e/day).

According to the methodology AM0018/Version01.1, no leakage is

considered. There are not additional electrical load that may result

from the project activity (actually, there are electricity savings due to

the project activity, but they are not considered in the calculation of

emission reductions as a conservative assumption). Thus, Cer1 = 0

and Cer2 = 0.

MONITORING REPORT

Petrotemex Energy Integration Project

21

Emission reductions per day related to

fuel savings due to the boiler steam

optimization in Cosoleacaque plant

Cer = Ein × Σ(Ffuel × %Hfuel)

where the sum extends to all fuels consumed in the boiler room, and:

Ein Energy input in the boiler room during the day

(MMBtu/day).

Ffuel Carbon dioxide emission factor per unit of energy of

fuel (tCO2/MMBtu).

%Hfuel % of hours per day for each type of fuel. It is

obtained from the actual consumption of fuels by the

boiler room9. Thus, the % of hours per day for each

type of fuel is equivalent to the proportion of fuel

consumed in the boiler room during the day (%).

Energy input in the boiler room during

the day Ein = Enet / ηb

where

Enet Net reduction in steam energy consumption during the

day (MMBtu/day).

ηb Efficiency of the boiler room (%).

Efficiency of the boiler room ηb = Eo / Ei

where

Eo Output energy of steam (MMBtu/month).

Ei Input energy of fuel (MMBtu/month).

Output energy of steam Eo = Es × S

where

Es Net enthalpy of steam (MMBtu/tonne).

S Steam generation by the boiler room (tonnes/month).

Net enthalpy of steam Es = Etot – Efw

where

Etot Enthalpy of steam at the boiler room outlet

(MMBtu/tonne).

Efw Enthalpy of feed water (MMBtu/tonne).

The steam enthalpy is obtained by using steam tables for enthalpy at

given pressures and temperatures.

The enthalpy of feed water is estimated by multiplying the feed

water temperature by the water specific heat (1 kcal/kg ºC).

NOTE: for this verification period, design values provided by

AMOCO for pressure and temperature of the steam and feed water temperature were used.

Input energy of fuel Ei = NCVfuel × F

where

NCVfuel Net calorific value of fuel (MMBtu/m3).

F Quantity of fuel consumed at the boiler room

(m3/month).

9 According to the methodology, under direct method of boiler efficiency estimation, fuel

metering/measurement facility is available. Thus, the % of fuel is derived by actual consumption of

respective fuel.

MONITORING REPORT

Petrotemex Energy Integration Project

22

Net reduction in steam energy

consumption during the day Enet = Snet × Es

where

Snet Net reduction in steam consumption during the day

(tonnes/day).

Es Net enthalpy of steam (MMBtu/tonne). It is estimated

through equation showed above.

Net reduction in steam consumption

during the day Snet = SSCRdiff ×××× Pact

where

SSCRdiff Difference in SSCR (Specific Steam Consumption

Ratio) of baseline and project scenarios during the day (tonne steam/tonne PTA).

Pact Actual PTA production during the day (tonne

PTA/day).

Difference in SSCR SSCRdiff = SSCR – SSCR1

where

SSCR SSCR of baseline scenario (tonne steam/tonne PTA).

SSCR1 SSCR of project scenario during the day (tonne steam/tonne PTA).

The SSCR of baseline scenario is calculated ex-ante and considered

fixed along the crediting period. It is determined using the same

formulae than the SSCR of project scenario.

SSCR of project scenario during the day SSCR1 = S1 / P1

where

S1 Representative steam consumption during the day

(tonne steam/day).

P1 Representative PTA production during the day (tonne

PTA/day).

Representative PTA production during

the day Prep1 = (P1 + P2…..+ Pm) × A / m

where

P1, P2,….Pm PTA production during the shift 1, 2,….m (tonne

PTA/shift).

A Total number of shifts per day.

The representative PTA production for the day is determined by

selecting and averaging the representative PTA production values

(i.e. within the normal production range). A “normal” production

range can be defined based on the relationship between production

rates and energy consumption. Based on general experience the

energy consumption per unit of production is not significantly

sensitive up to +/- 5% of the normal production. The normal

production range can be defined as the range in which production

levels are 5% above or below the normal production. If production

fluctuates beyond this normal production range, these specific values

can be excluded to derive a representative production level of the day.

NOTE: for this verification period there is only one data per day.

Representative steam consumption

during the day Srep1 = (S1 + S2…..+ Sm) × A / m

where

S1, S2,….Sm Steam consumption corresponding to the PTA

production during the shift 1, 2,….m (tonne

steam/shift).

A Total number of shifts per day.

The representative steam consumption for the day is determined by

selecting and averaging the steam consumption values corresponding

to the PTA production values included in the calculation of the

representative PTA production for this day.

NOTE: for this verification period there is only one data per day.

Total emission reduction ER of the

project activity ER = EREG + ERFS = BEEG + Σ Cer

where BEEG and Cer are determined as explained above.

There are not identified sources of project emissions PE and leakage

LE associated to the proposed project activity. Then, PE = 0 and LE

= 0.

Thus, the total annual emission reductions ER of the project activity

result to be:

ER = BE – PE – LE = BE

Thus, emission reductions are equal to baseline emissions that

include (i) CO2 emission from fuels that would have been used at the

boiler room of Cosoleacaque plant in order to generate the quantity

of steam saved by the proposed project activity, and (ii) CO2

emissions from fuels that would have been used by the operation of

grid-connected power plants and by the addition of new generation

sources, in order to generate the quantity of electricity self-generated by Cosoleacaque and Altamira plants following project

implementation. Then:

ER = BE = BEEG + Σ Cer

9 EMISSION REDUCTION CALCULATION
