The first step in evaluating and/or designing a gas dehydration system is to determine the water content of the gas. The water content of a…
Gas dehydration is the process of removing water vapor from a gas stream to lower the temperature at which water will condense from the stream.…
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. Their duty can be determined from the concepts in Chapter 3 as required to cool the overhead…
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 arnine solution from the absorber is flashed to a separator to remove any hydrocarbons. A small percentage of acid gases will also flash…
