2. PROJECT OVERVIEW
2.1 General
2.1.1 Plant Description
The Project will detail the design, build and commission a carbon capture and conditioning plant capturing
CO2 from the flue gas from Norcem’s cement production plant in Brevik, Norway and conditioning it for
ship transportation and permanent storage below the sea bed on the Norwegian continental shelf within the
Northern Lights Project.
The carbon capture and conditioning plant shall have a design capacity of 55 tons liquid CO2 / hour, and the
target CO2 capture rate is 400 000 tons CO2 / year. The yearly CO2 capture capacity is based on available
waste heat (thermic energy) recovered from existing cement process and from the capture and conditioning
process itself. As a result, only electricity and no additional heat or fuels are required for CO2 capture.
The carbon capture and conditioning plant will be installed in parallel to the existing flue gas system with
focus on safe, easy and smooth changeover between cement production with and without carbon capture and
heat recovery thus securing the integrity of the cement production.
To integrate the carbon capture and conditioning plant with the existing cement plant, some modifications to
the existing cement plant are needed. The Contract Object, specified in section 3.2, comprises the necessary
modifications of the existing flue gas system due to modified operating conditions and new tie-ins, ducts,
fans, dampers, etc. needed to connect the waste heat recovery units and the carbon capture plant to the flue
gas system.
The Contract Object shall satisfy the requirements described in Norcem’s Overall Design Basis for the CCS
Project. The Contract Object shall with the exception of wear and tear parts have a technical design life of 25
years.
The elements of the CCS Facility can be divided into the following main categories:
▪ Carbon capture, conditioning, intermediate storage and loading (not Contractor’s scope)
▪ Waste heat recovery from existing cement production process (not Contractor’s scope)
▪ Modifications of existing flue gas system (Contract Object)
▪ Utility systems (split scope)
▪ Civil works (not Contractor’s scope)
Contractor is the EPC contractor for the necessary modifications of the existing flue gas system.
A 3D view of the complete new plant from the project 3D BIM model is shown in Figure 1 below. The
coloured elements are new, while the grey elements are part of the existing cement plant.

Contractor’s scope of work includes supply of all equipment and services required for the establishment of
all new tie-ins into existing flue gas system
Contractor shall supply the following main components:
▪ Tie-ins according to Table 4.
Flue gas ducts
The new installations require both new ducting and modification of existing ducting. In tight spaces, existing
ducting shall be modified by Contractor to gain space for new dampers and tie-ins.
Circular ducts are preferred as they minimise the amount of steel required and are less expensive to fabricate.
However, in tight spaces ducting with rectangular cross section may be used. All ducts are made from mild
steel with external stiffeners. A corrosion allowance of 1-2 mm shall be included.
When selecting actual cross section area, a flue gas design velocity in the range 15-20 m/s is used to avoid
dust settling while maintaining an acceptable pressure loss. Pressure loss calculations shall be performed for
all new ducts to verify flue gas velocity and thus duct dimensions.
The only surface treatment required is a transport primer. To avoid heat loss and condensation of moisture in
the flue gas inside the ducts, they shall be insulated with 100 mm mineral wool covered with cladding.
Expansion joints shall be provided on new ducts and to tie-ins where necessary to handle vibration and
thermal expansion in accordance with HeidelbergCement’s Mechanical DCS “Expansion Joints” (Ref. 9).
Slide brackets, saddles and pendular supports will support the ducts in a way that allow, and control needed
movement due to thermal expansion. Supports shall where possible be attached to existing structures thus
reducing the need for additional foundations.

Flue gas crossover fan from string 2 to string 1
Flue gas crossover from string 2 to string 1 is required as there is not enough CO2 to be captured from string
1 alone to reach the yearly capacity of 400 000 tones CO2. Flue gas must be added from string 2.

These interface points are shown on the Flow diagram NC03-NOCE-P-XA-0001, page 1 and 2 (Attachment
A02) and further specified in the Interface register (Attachment A04).
Flue Gas Fan and DCC
The CO2 capture plant will extract flue gas from the flue gas tie-in (GS-117), which is located between
existing Fabric Filter Fan on String 1 and existing stack (Stack No 3) at Norcem. The existing stack will not
be used after implementation of the CO2 capture plant, except for special occasions when the CO2 plant needs
to be entered for maintenance inside flue gas ducts or columns.
Flue gas is routed through a new duct from the flue gas tie-in to the CO2 capture plant main process area
where the new Flue Gas Fan is located. There is a bypass duct from upstream of the Flue Gas Fan and into
the new stack located on top of the Absorber. There is a bypass damper at the entrance to the bypass duct,
and there is an inlet damper at the entrance to the Flue Gas Fan and CO2 capture plant.
The bypass damper is provided with 'Lock Open' arrangement to secure free flue gas flow path without
depending on a control system to open it.
The Flue Gas Fan located downstream of the inlet damper fan will be equipped with Variable Speed Drive
(VSD). Flue gas flow and temperature measurements in the bypass duct will be used for controlling the fan
speed, aim is to maintain close to zero flow in the bypass during normal operation. The pressure conditions
downstream of the existing Filter Fan will be approx. 5 mbar higher than today due to increased pressure loss
in new ductwork, mixing device in stack and the stack itself. Since the bypass damper is locked open,
pressure will be maintained fairly constant and nearly independent of CO2 capture plant operation or flue gas
bypass operation.
Downstream of the Flue Gas fan, the flue gas enters the Direct Contact Cooler (DCC), where the flue gas
flows counter-currently to water in a packed bed with structured packing. The flue gas is cooled beyond its
dew point and the DCC is therefore a net water producer. Hence a condensate bleed is established,
containing traces of sodium sulphite, sodium sulphate and possibly traces of suspended fines from the flue
DRAFT 19 Aug 2020 24(49)
gas. The bleed will be partially utilized as process water for Norcem’s existing cement plant, i.e. as makeup
water to the Gas Suspension Absorption (GSA). The remaining bleed is sent to an Effluent Water Treatment
Plant (EWTP) for purification before released to sea. During Low- Alkali (LA) clinker production, the GSA
is out of operation, hence the whole DCC bleed will be treated in the effluent water treatment plant (6 m3).
During standard clinker production, the GSA is in operation and the flue gas has higher water content, which
implies the bleed rate becomes larger (11 m3/h). The increased bleed corresponds to the water injected in the
GSA (approx. 5 m3/h). This excess bleed is then routed to the GSA where the water is reused as GSA feed
water.
Waste Heat Recovery Arrangement
Waste heat from the following three gas streams in the existing cement plant is recovered:
▪ Flue gas from preheater String 1
▪ Flue gas from preheater String 2
▪ Excess hot air from clinker cooler
The waste heat is recovered from the three gas streams by several steam generating boilers/ Waste Heat
Recovery Boilers – (WHRBs). The WHRBs for each string forms a Waste Heat Recovery Unit (WHRU)
where all boilers are operating in series on the flue gas side.
The WHRU installations are installed in parallel to the existing flue gas ducting. In this way the cement
production plant can operate independently of the WHRUs as these can be bypassed when not in operation.
WHRUs for string 1 and 2 are arranged downstream the existing Gas Conditioning Towers (GCT 1 and 2)
and the Electro Static Precipitators (ESP 4 and 3 respectively). To achieve highest possible heat recovery a
high flue gas temperature on the boiler inlet is required. The cooling service in the cooling towers are
therefore reduced/ stopped during operation of the waste heat recovery units.
The WHRU installation for the hot air from clinker cooler are arranged downstream the existing hot air
chimney.
The WHRU integration to existing plant is shown in Figure 4.
DRAFT 19 Aug 2020 25(49)
Figure 4 - Overview of the cement production process flow with WHRU systems and tie-ins
Waste Heat Recovery Boilers (WHRB) / Waste Heat Recovery Units (WHRU)
Two or more Waste Heat Recovery Boilers (WHRB) forms a Waste Heat Recovery Unit (WHRU) where all
boilers are operating in series.
Boiler design
The WHRBs are of standard shell boiler type where the hot flue gas is led through the internal flue gas tubes
being submerged in water. The hot flue gas heats the water to its boiling point before it evaporates as steam.
To recover as much heat as possible from each unit the WHRBs are designed for an optimum flue gas
velocity through the flue gas tubes to avoid excessive pressure loss and prevent scaling and erosion
dependent on type of dust in the flue gas. The average flue gas speed through WHRU 1 and 2 is 40 m/s (to
limit scaling), and through WHRU 3 it is 30 m/s (to limit erosion).
WHRU 2 will operate with two different flue gas flow rates depending on clinker production mode, LA or
Standard. The WHRU 2 boilers are designed for a flue gas flow related to Standard clinker production (high
flue gas flow). During production of LA clinker the flue gas flow will be approx. 30% lower than during
production of Standard clinker, and this consequently reduces the flue gas velocity in the boiler tubes. If
operational experience shows that scaling becomes an issue due to this reduced velocity, the solution will be
to block some of the boiler flue gas tubes by a damper. The inlet ducting is prepared with space for a damper
by installing a straight ducting upstream the WHRB 2.1.
Dust handling for boilers
DRAFT 19 Aug 2020 26(49)
The flue gas contains dust. Normal operating value for dust concentration on WHRU1 and 2 inlets is 0,1
g/Nm3, but they are designed to operate with a dust concentration of 1 g/Nm3. For WHRU 3 the normal
operating value for dust concentration on inlet is 0,005 g/Nm3.
The inlet and outlet duct/ chamber of the boilers are designed as a semicircle to match with the inlet section
of the flue gas pipes inside the boilers to avoid large variations in flow profile in and out of the boiler. The
inlet duct of each boiler is designed without hoppers for dust collection, thus all dust will pass through the
WHRUs. However, both inlet and outlet chambers on each boiler are equipped with hatches (typ. 500 x 700
mm) for inspection and cleaning purposes.
3.4 Plant Operability
All new plant shall be designed, arranged and equipped so the change-over between operating the cement
production with or without the CCC plant and the waste heat recovery units in operation is smooth and can
be done without stopping the cement production.
