Gas To Liquid

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.

Steam methane reforming (SMR) is a dominant technology for hydrogen production. For the highly energy-efficient operation, robust energy analysis is crucial. In particular, exergy analysis has received the attention of researchers due to its advantage over the conventional energy analysis. In this work, an exergy analysis based on the computational fluid dynamics (CFD)-based method was applied to a monolith microreactor of SMR. Initially, a CFD model of SMR was developed using literature data. Then, the design and operating conditions of the microreactor were optimized based on the developed CFD model to achieve higher conversion efficiency and shorter length. Exergy analysis of the optimized microreactor was performed using the custom field function (CFF) integrated with the CFD environment. The optimized catalytic monolith microreactor of SMR achieved higher conversion efficiency at a smaller consumption of energy, catalyst, and material of construction than the reactor reported in the literature. The exergy analysis algorithm helped in evaluating length-wise profiles of all three types of exergy, namely, physical exergy, chemical exergy, and mixing exergy, in the microreactor.
