OVERVIEW

The Exterran Processing SolutionsTM A500

Amine System removes contaminants such

as carbon dioxide and hydrogen sulde rom

natural gas streams in order to meet pipeline

or pretreatment specications.

This system operates at a 500 GPM

circulation capacity and handles inlet gas

rates o 25 to 130 MMscd.

Exterran has unmatched expertise in

engineering state-o-the-art plant designs and

brings them online quickly, so you can see

production prots aster.

PROCESS DESCRIPTION

Untreated natural gas containing carbon dioxide (CO2) and hydrogen sulde

(H2S) fows into the amine contactor where it contacts a downward-fowing

amine-water solution. The amine solution chemically absorbs CO2

and H2S

rom the gas stream.

As the amine solution is re-circulated, rich amine solution collects at the

bottom o the absorber and level controlled to a fash tank. The rich amine

is then cross exchanged with lean amine.

Rich amine solution is urther treated in a stripper or still. The still has an

external, indirect heating system that heats the rich amine solution. As it is

heated, steam rom heating the amine rises as rich amine fows downward

through the still column, stripping out the CO2 and H2S. The lean amine

solution accumulates at the bottom o the still.

CO2, H

2S and water vapor separated in the amine still are cooled in air

exchange coolers. Condensed water is returned to the amine still. CO2

and

H2S exit the system at low pressure. Lean amine solution is cycled through

the absorber to repeat the process.
