How Sensitive is Your Treating Plant to Operating Conditions
(March 2014) This paper analyzes why small changes in operating conditions can result in correspondingly large variations in the performance of a Piperazine activated CO2 removal system and therefore why it is important to provide an adequate design margin in pumps, heat transfer equipment, and columns. The analysis is done via the rate-base simulations performed in ProTreat®.
