CASE STUDIES
Case Study 1: NGL Recovery Debottlenecking & Capacity Enhancement
Challenge Faced
-
Operating issues in amine, mole sieve dehydration, condensate stabilizer, and demethanizer units
-
Client wanted to increase plant capacity above nameplate capacity
Value Delivered
-
Increased plant capacity from 250 to 400 MMscfd (60% increase to the existing nameplate capacity) with $0.80/scf
-
Debottlenecked operating issues of existing process units
Case Study 3: Operational Improvement for a NGL Recovery Plant
Challenge Faced
-
Client wanted to increase the NGL facility performance (more profit)
-
Client wanted to save energy
-
Client wanted to further throughput
