Amine systems are extremely corrosive due to the acid-gas concentrations and the high temperatures. It is important that all carbon steel exposed to the amine…

Due to side reactions and/or degradation, a variety of contaminants will begin to accumulate in an amine system. The method of removing these depends on…
The amine cooler is typically an air-cooled, fin-fan cooler, which lowers the lean amine temperature before it enters the absorber. The lean amine entering the…
Rich/lean amine exchangers are usually shell-and-tube exchangers with the corrosive rich amine flowing through the tubes. The purpose of these exchangers is to reduce the…
Amine-stripper overhead condensers are typically air-cooled, fin-fan exchangers. The inlet temperature to the cooler can be found using the partial pressure of the overhead steam…
Amine strippers use heat and steam to reverse the chemical reactions with CO2 and H2S, The steam acts as a stripping gas to remove the…
The reboiler provides the heat input to an amine stripper, which reverses the chemical reactions and drives off the acid gases. Amine reboilers may be…
The rich amine solution from the absorber is flashed to a separator to remove any hydrocarbons. A small percentage of acid gases will also flash…
The circulation rates for amine systems can be determined from the acid gas flow rates by selecting a solution concentration and an acid gas loading.…
Amine absorbers use counter-current flow through a trayed or packed tower to provide intimate mixing between the amine solution and the sour gas. Typically, small…
