Steam Methane Reforming of Natural Gas with Substantial Carbon Dioxide Contents – Process Optimization for Gas-to-Liquid Applications

Abstract:

Steam methane reforming has been a conventional process to produce synthesis gas which is an important feedstock to many chemicals. However, for gas to liquid (GTL) applications this reforming process is not suitable as it produces synthesis gas with very high hydrogen to carbon monoxide ratio than required by the Fischer Tropsch synthesis in GTL line. In this work, a GTL process is designed in which synthesis gas is produced by steam reforming from a natural gas feedstock containing relatively substantial carbon dioxide contents in it. Synthesis gas composition is tailored by tail gas recycling from the Fischer Tropsch products. Process simulation and optimization is performed on Aspen HYSYS to produce synthesis gas with hydrogen to carbon monoxide ratio of 2 which is desired in GTL technology.
