Contamination in Amine Systems - Refining Community

2017-8-3  The iron sulfide layer is soft and friable; it can be worn away by high flow velocity or turbulence. High HSS content increases the viscosity and density of the amine solution. At the same time if higher amine solution circulation rates are required to circulate enough free amine to pick up the acid gas, solution velocities go up.

Lean Amine / Rich Amine Analysis Applied Analytics

Introduction. Amine gas treating is used to remove H 2 S and CO 2 from sour gas for environmental reasons. In the absorber unit, an amine solution absorbs H 2 S and CO 2 molecules from the feed gas in order to “sweeten” the upflowing gas stream.. Gradually, the amine becomes “rich” (i.e. saturated) with absorbed H 2 S/CO 2 and loses scrubbing efficiency. The rich amine must be sent to ...
