Is a compressor needed in the methanol-to-olefins process?

It is necessary; after the reaction, the gas produced needs to be rapidly cooled, and then compressed using a compressor – namely, a conventional pyrolysis gas compressor. An acrylic refrigeration compressor is also required, and sometimes an ethylene refrigeration compressor as well; these are commonly referred to as the \"three compressors\".
So you mean that the process of producing olefins from methanol is similar to the process of producing olefins through oil refining? The ethylene tri-machine you mentioned is used in the petrochemical industry, right?
The methanol-to-olefins process consists of a reaction step and a separation step; the separation step is basically similar to that in the oil refining-based olefins production process, so three types of machines are definitely required.
If it is a fluidized bed reactor, a main fan is also required. Flue gas turbines and ethylene expanders may also be used.
Even if the main unit is designed to be so efficient that no compressor is needed, compressors are still used in the utility systems. At the very least, the electric pump at the factory entrance that inflates tires for employees who commute by bicycle is also a type of compressor. There’s no electric pump; a hand pump can be used, which functions as a compressor as well, manually operated. Answer: It will be used.
Classmates, does the pyrolysis gas compressor used in the separation process also tend to produce coal tar?
Not easy! The pyrolysis gas during the separation process comes from methanol MTO/MTP, and it has little to do with coal anymore. Of course, it is normal to have some heavy hydrocarbon condensate during inter-stage cooling of the compressor.
Green oil precipitates in the last stage of the process gas compressor; this phenomenon also occurs in ethylene process gas compressors.
