Description
This is a market dataset representing the consumption market in the region. It includes transportation of the product from the factory gate to consumption, with transport services calculated according to the regional transportation conditions for the product.
Activity Description
The process flow for producing propylene from coal-based methanol includes coal powder gasification, purification, methanol synthesis, distillation, olefin separation, olefin cracking to produce ethylene, ethylene oxidation to produce ethylene oxide, and ethylene oxide hydration to produce ethylene glycol.
Process Description
Propylene is an organic compound with the molecular formula C3H6. It is a colorless, odorless gas with a slightly sweet smell. It is flammable and produces a bright flame when burned, with an explosive limit in air of 2% to 11.1%. It is insoluble in water but readily soluble in ethanol and ether.

Technology comment
The specific process includes: (1) pulverized coal gasification to produce raw synthesis gas, which undergoes sulfur-resistant partial conversion via Co-Mo catalytic process, followed by cold methanol washing for sulfur recovery with liquid sulfur as a by-product. (2) The purified synthesis gas is processed through low-pressure methanol synthesis units (e.g., Lurgi process), methanol distillation columns, and hydrogen recovery units to produce methanol; the methanol is then separated into olefins via MTO (methanol-to-olefins) technology, and the olefins are cracked to produce ethylene. (3) Ethylene is oxidized to produce ethylene oxide, which is then hydrated to produce ethylene glycol.
