Several proprietary processes have been developed based on the hot carbonate system with an activator or catalyst. These activators increase the performance of the hot…

The hot potassium carbonate (K2CO3) process uses hot potassium carbonate to remove both CO2 and H2S. It works best on a gas with CO2 partial…

Diisopropanolamine (DIPA) is a secondary amine used in the Shell ADIP® process to sweeten natural gas. DIPA systems are similar to MEA systems but offer…

The Fluor Econamine® process uses diglycolamine (DGA) to sweeten natural gas. The active DGA reagent is 2-(2-amino-ethoxy) ethanol, which is a primary amine. The reactions…

Diethanolamine (DBA) is a secondary arnine that has in recent years replaced MEA as the most common chemical solvent. As a secondary amine, DEA is…

Monoethanolarnine (MBA) is a primary amine that can meet nominal pipeline specifications for removing both H2S and CO2. MBA is a stable compound and in…

Several processes are available that use the basic action of various amines. These amines can be categorized as primary, secondary, or tertiary according to the…

Chemical solvent processes use an aqueous solution of a weak base tochemically react with and absorb the acid gases in the natural gas stream.The absorption…
