The three technologies (Syngas generation, Syngas conversion and Hydro processing) for the conversion of natural Gas to hydrocarbon Liquids (GTL) have been optimized individually, but not integrated. In order to make the GTL technology more competitive, process integration is inevitable. Process optimization study was performed on a Gas-to-Liquids process to determine the optimum parameter and identify factors influencing carbon efficiency, methane slip and energy utilization using Aspen Hysys. Exergy analysis (using exercom) was used to analyze energy requirements for the process. Process integration based on exergy analysis results into 113.5MW heat recovery for power generation, 57.4% tail gas and process water for other purposes.
