Process Principle
• Bulk H2S or CO2 removal from highly sour gas
by high pressure cryogenic distillation

or solid products formation
• Separated acid gases are recovered liquid
at high pressure and easily pumped back
into reservoir
• Final sweetening of partially treated gas may
be done with a conventional amine unit
