Large-scale Production of Alternative Synthetic Fuels from Natural Gas

摘要

Production of alternative liquid fuel from natural gas is an important option for the exploitation of remote gas fields. The products can be fuel methanol, synthetic gasoline and diesel fuel, and substitute fuels such as Dimethyl Ether (DME) which has been demonstrated to have attractive properties as a substitute diesel fuel. In each case the synthesis of the product requires preparation of synthesis gas with specified properties, and in all cases is the synthesis gas section the most important part of the plant both in terms of initial investiments and in operating costs. Furthermore, proper integration of the synthesis gas section with other sections of the plant including the steam and power system is very important for the optimization of the overall process concept.
