CONSER offers technology for the complete design (Basic Process Book) of gas treating units. Projects are supported by the know how and experience of CONSER alone or in collaboration with selected partners.
In addition to the design of new units, typical gas treating projects carried-out by CONSER include the following:

• Selection of the most appropriate solvent depending on specific application (MEA, DEA, MDEA, DGA, UCARSOL, GAS SPEC)
• Troubleshooting (corrosion, foaming)
• Debottlenecking towards increased capacity and energy savings
• Drying and purification for petrochemical applications

PROCESS DESCRIPTION (Amine washing)

Sour gas is washed by counter-current contact with lean solvent to absorb H2S and CO2. Clean gas is discharged overhead, while rich solvent is flashed to minimize HC content. Rich solvent is preheated and fed to regeneration column where acid gas is stripped out and discharged to a Claus unit for sulphur recovery. Lean solution from the bottom of regenerator is cooled, filtered and recycled back to the absorber.
