Sour Gas Processing and Conditioning

Amine regeneration costs consume massive amounts of energy, much wasted due to over-stripping. Energy use can be dramatically minimized by accurate and reliable analysis of the residual H2S in lean amine.

The Model 4650 measures the concentration of residual H2S in the lean amine stream exiting the steam-stripping column. The sample enters the analyzer through a bypass filter system that removes all solid particulates from the amine. The amine stream continually flows through the measurement sample cell where it is analyzed by the UV photometer. The sample is returned to the process at a low pressure point which ensures sample flow.

This application presents a real analytical challenge due to the low H2S concentrations and the varying presence of numerous, interfering additives and corrosive compounds. The AMETEK Model 4650 solves this problem by using the amine itself as a zero fluid through a unique and clever process.
