Overview of the
Amine Guard FS Process
 Licensed amine technology
 Removal of CO & H S to low levels or
2 2
 Selective H S Removal
2
– Low H S spec, with as much as 75% CO slip
2 2
 UCARSOL Formulated Solvent from Dow
 Several flow scheme options available
 UOP MD™ Trays or Raschig Super Rings to maximize
performance

Overview of the
Amine Guard FS Process
Markets served include:
 Synthesis gas treating for CO removal in synthesis
2
gas plants, such as direct iron ore reduction
 Synthesis gas treating for selective H S removal in
2
integrated gasification combined cycle (IGCC)
plants
 Natural gas treating for selective removal of H S
2
and partial removal of CO for pipeline
2
specifications
 High CO partial pressure service for reduced
2
energy consumption compared with conventional
amines, such as steam reformed ammonia plants

UCARSOL Solvent Characteristics
UCARSOL AP-800 Series Solvent Features:
State of the art amine technology
MDEA based solvent with low concentrations of
activator
– Activator accelerates slow overall kinetics of CO
2
reaction with MDEA
– Solvent formulation is chosen to provide the desired
amount of CO slip
2
– AP-814 used for LNG applications to achieve very low
residual H S & CO content of product gas
2 2
– Activator significantly reduces packed heights of
towers

UCARSOL Solvent Characteristics
UCARSOL AP-800 Series Solvent Features (cont’d):
 High thermal and chemical stability
 Non-corrosive (no corrosion inhibitors needed)
 No solvent reclaiming or purging for typical
applications
 Non – foaming
 Inventory stored in worldwide locations

Amine Guard FS Flow Scheme Options
 Feed CO & H S partial pressures vs. product specs
2 2
 Higher PP allows exploitation of flash regeneration
 Low level H S product specifications require some

thermal regeneration
 Each application will have its own optimal flow
scheme solution
