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…
The molecular sieve process uses synthetically manufactured solid crystalline zeolite in a dry bed to remove gas impurities. The crystalline structure of the solids provides…
The zinc oxide process is similar to the iron sponge process. It uses a solid bed of granular zinc oxide to react with the H2S…
SulfaTreat® process is similar to the iron sponge process. It uses a patented proprietary mixture of ferric oxide and triferric oxide to react with H2O…
The iron sponge process uses the chemical reaction of ferric oxide with H2S to sweeten gas streams. This process is applied to gases with low…
A fixed bed of solid particles can be used to remove acid gases either through chemical reactions or ionic bonding. Typically, in solid bed absorption…
