Conceptual Design of GTL (Gas to Liquid) Complex - Modeling and Optimization of Reforming Process

초록

Gas to Liquid (GTL) Process has been recently spotlighted as one of major clean energy technologies for the production of synthetic fuel. This work is aimed at developing an optimized reforming process that is a part of GTL process to convert natural gas to synthesis gas. First, steam and CO2 reforming reaction system was modeled based on detailed reaction kinetics using Matlab software. For the design of fired reactor, three commonly used industrial-used reactor designs were compared to find the most efficient design. Secondly, various process configurations were considered by using commercial process design software, Aspen HYSYS� that was integrated with the reactor model. Lastly, operating condition such as feed composition, reactor temperature, and pressure were optimized. As a result, the optimized reforming process was developed that shows higher energy efficiency and lower CO2 emission, especially when it is compared with the reforming process that uses only steam for reaction.
