Improving energy efficiency combined with reducing
greenhouse gas emissions are key in the five year plan

on the ME for most
of its oil supplies
which is sour

Case Study Comparing SMR & Gasification
1. Basis
Natural Gas Price: $13/MMBtu (HHV = 22,400 Btu/lb) - based on LNG imports
Petcoke Price: $1/MMBtu (HHV = 15,000 Btu/lb)
Coal Price: $3.50/MMBtu (HHV = 12,000 Btu/lb)
Hydrogen required for refinery: 100,000 Nm3/h

What is the new UOP SeparALL Process?
Absorption / regeneration process for selective removal of H2S, COS, & CO2
Uses “Next generation” physical solvent (SELEXOL™ MAX Solvent)
– Chemically similar and completely compatible with SELEXOL Solvent
– Clear fluid that looks like tinted water
Solvent regenerated by changing pressure, temperature or applying a stripping gas
Physical vs Chemical Typical Gasification Application
High Pressure is advantageous

Two Basic Flow Schemes
Sulfur removal only
Typically for power and hydrogen applications
Can reduce treated gas any desired sulfur level
One solvent absorber with solvent regeneration
Sulfur removal with separate CO2 removal (CCS or chemicals production)
Typically for chemicals, SNG or coal to liquids applications
Typically involves more stringent product specifications
Integrated solvent absorbers and solvent regeneration

UOP SeparALL Process - Advantages
Solvent: high vapor pressure (low losses) and non-toxic
Mild Chilling
Simple flow schemes with few pieces of equipment
Absorbs NH3, HCN and other trace contaminants, without the need for additional equipment
Removes metal carbonyls
Metal carbonyls in treated syngas decompose at gas turbine burners and potentially plate-out on the gas turbine blades
Metal carbonyl can also act as catalyst poisons for chemical applications
11
Through its improved efficiency and next generation
technology, the SeparALL process can reduce capital
expenditures by up to 10 percent and operating
expenditures by more than 20 percent.

PSA with Maximum On-Stream Reliability
For a customer in China that needs a reliable source of
high purity hydrogen, UOP Polybed™ PSA provides greater
than 99.8% on-stream availability that results in $500,000/day
of additional value due to downtime avoided versus local
PSA suppliers. We do this by providing proven designs,
proprietary adsorbents, and equipment.
21
Assumptions:
• 100,000 Nm3/hour product PSA unit
• H2 value = 15000 RMB/MT = $0.21/Nm3
• Calculation: 100,000 x 24 x 0.21 = $504,000/day
• The cost from the loss of production from the
downstream hydroprocessing units, if known,
would be added to the cost of the loss of H2
