The interactions of an integrated gas to liquids process were investigated with specific focus on factors influencing the carbon efficiency. Exergy analysis was used to optimize process parameters such as carbon efficiency, methane slip and energy utilization. It was found that relatively low autothermaJ reformer (A TR) temperatures increase the carbon efficiency and exergetic efficiency. At ATR temperatures around 905"C, exergy losses are minimized and the maximum exergy is stored in the liquid hydrocarbon product rather than in utilities (ie, electricity) produced by the process.
