Improve Your Gas Plant's Performance in the Middle East Part I: The Amine Plant

This is Part I of a series of papers detailing a method to optimize a gas plant, while being thoughtful of downstream implications. Amine sweetening units are often at the front end of the gas plant and pose significant design and operation challenges to downstream operations. This paper compares DGA®, DEA, MDEA and MDEA + piperazine when selecting the amine solvent to use. It also shows the steps taken to determine the correct operating conditions for high pressure, high temperature and highly sour environments. While MDEA is routinely lauded for selectively removing H2S, this paper shows the selectivity is greatly diminished in these conditions and that DGA® may be the more appropriate solvent.
