BTX aromatics,also known as benzene,toluene,and xylene,are one of the most important production raw materials in the chemical industry.Currently,they are mainly obtained through petroleum cracking methods.In order to further explore the issues of immature BTX production process and excess methanol production capacity,this paper studies the optimization of the coal based methanol to aromatics process(MTA).Through a combination of theory and practice,a scheme is proposed to use Aspen Plus to optimize the coal based methanol to aromatics process,and the MTA process is coupled with the alkylation reaction of benzene and methanol in series.After research,it was concluded that the production of toluene and xylene significantly increased after process optimization,reaching 165.54 kg/h and 273.89 kg/h respectively,and reducing process energy consumption,which is conducive to the implementation of low-carbon emission reduction policies.
