Design and Simulation of Natural Gas Liquid Recovery Process from Rich Natural Gas

Natural gas plays a growing role in the energy mix by displacing coal due to its relative economic and/or environmental advantages A process of natural liquid (NGL) recovery utilizing internally generated achieve efficiency was designed. The utilizes heat from compressor end turbo-expander provide required maintain appropriate operating conditions at intermediate and bottom sections demethanizer column, rather than dedicated steam generators that requires additional construction, installation, operations maintenance cost. Simultaneously, temperature hot residue is also dropped range for export, coolers. various unit such as exchangers, separators, Joules Thompson Valve coefficient, reflux condenser, reboiler were designed, cost evaluation performed each unit, while models solved using MatLab software. quality composition NGL produced are consistent with industrial plant data. In addition, condenser showed removed 3.180.5kW 1.65m 2 area exchanged, 474.5kW 47.25m exchanged area. Also, profile column not uniform lower rectifying section (cryogenic absorption). Thus, -90 o C – 95 favours production sales top product stream, 30 36 stream. height diameter distillation absorption 28m 1.55m 7.24m 3m respectively.
