In an MTO unit
Feedstock
The process converts methanol into other compounds.
From a small molecule to industrial materials
A methanol molecule contains one carbon atom. Ethylene contains two, and propylene contains three. In a plant designed to make olefins from methanol, carbon from that small molecule can become part of larger molecules used to manufacture plastics. The transformation begins in a reactor, several steps before a finished product takes shape.
How methanol becomes ethylene and propylene
In methanol-to-olefins (MTO) plants, methanol reacts over catalysts to form light olefins, chiefly ethylene and propylene. Temperature, pressure, and catalyst selection shape how much of each olefin the unit yields.
Those olefins feed polymerization routes behind many everyday plastics—ethylene for film and flexible packaging, propylene for molded containers and rigid parts—linking a single-carbon feedstock to finished goods several steps downstream.

Solvent
Its role is to help dissolve substances during processing.
That difference matters when discussing a supply requirement. Naming the application gives the supplier context, while the plant's purchasing specification defines the criteria the product needs to meet.
