Techno-economic analysis of potential natural gas liquid (NGL) recovery processes under variations of feed compositions

► Six representative industrial NGL recovery processes such as ISS, GSP, CRR, RSV, IPSI-1 and IPSI-2 are rigorously evaluated. ► Operational performance and economic assessment of the candidate processes are rigorously studied. ► The useful guideline is suggested to decide and select the appropriate process scheme for various typical feed cases. ► IPSI-1 process gives the best economics in terms of TAC.
