Description

Crude ethylene is dry gas with a high concentration of ethylene equal of higher than 40%.

The source of the dry gas can be a gas-phase composition which is not subjected to cryogenic processing by a methanol-to-olefin and light hydrocarbon cracking device, and can also be a mixture of other sources, and other compositions in the mixture can be H2, methane, ethane, nitrogen, propane, propylene and the like.

Typical mass and volume fractions of compounds in a crude ethylene example from China are:

Compound Mass Fraction (%) Volume Fraction (%)
Ethylene     48.80     32.12
methane     24.40     28.10
ethane     23.40     14.37
nitrogen       0.60       0.39
carbon monoxide       0.15       0.10
C3's and above       0.05       0.01
