Cost-effective design reduces C2 and C3 at LNG receiving terminals

05/26/2003
An LNG receiving terminal with a C2+ or C3+ separation facility can receive LNG feeds with varying compositions, meet stringent calorific value export gas specifications, and decrease capital and operating costs. A study shows that process schemes for extracting C2 or C3 from rich imported LNG are feasible, effective, and economical.A minor required change in typical LNG receiving terminal equipment includes modification of the sendout pumps' casing to a higher pressure rating; however, no additional compression is required.Compared to a system that requires sendout gas compression or an inert-gas injection system to dilute the sendout gas, C2+ or C3+ separation can reduce the capital...
