Study finds optimum compressor interstage pressure

A study has found that the choice of the optimum compressor interstage pressure is an economic decision that can be estimated by equal compression ratios for each stage and adjustments to minimize total power requirementsThe study involved:• Rigorous process simulation for determining the optimum interstage pressure for a two-stage compressor.• A sensitivity study to simulate the gas compression process. Investigated were the effects of interstage pressure variation, presence of water vapor in the feed gas, effect of feed-gas temperature, and impact of heavy ends in the feed gas.• Creation of an optimized gas compression strategy through the use of commercial simulati...
