Abstract: A model for simulation of 200kt/a MTG plant was developed using the ASPEN PLUS software. In this model, C6+ mixture in hydrocarbon feed was represented as a pseudo component with distillation range from 68℃ to 201℃. The product distribution, gasoline yield and properties and the utility consumption of unit were investigated. Results show that RVP and the yield of C5-C10 are the most important factors which affect the yield of MTG gasoline, and the yield of MTG gasoline produced from various feedstocks is also proportional to the content of C4 fraction in the gasoline. It is showed from the analysis of energy consumption that a large proportion in the overall utility consumption is occupied by the electricity and steam, in which the consumption of electricity of gas-recycle compressor accounts for 40.2%. Reaction heat in MTG reactors could be used to generate medium pressure steam, by which the energy consumption of the plant can be reduced greatly.
