Abstract:
Objective The aim is to provide a theoretical data support for the industrial test of 10 000-ton class methanol coupled light hydrocarbons aromatization reaction, and to guide the operation of industrial test.
Method The simulation calculation of methanol coupled light hydrocarbons reaction process was carried out by Aspen Plus, and the reaction results were compared with the real reaction system. On the basis of the simulation calculation, combined with the previous laboratory research results, the 10 000-ton class industrial test scheme was prepared.
Result It was found that the product composition of the outlet of the simulated reactor was close to the test results. The average yield of aromatics was above 30% and the adiabatic temperature rise was less than 41 ℃ when the feed temperature was 320−380 ℃.
Conclusion The methanol coupled light hydrocarbons aromatization reaction is mild and controllable, the industrial scale-up process is easy to control, and there is no phenomenon of reaction bed temperature runaway. The technology scheme of 10 000-ton class methanol coupled light hydrocarbons aromatization reaction will lay a technical foundation for the development of industrial test and industrial application.
