Abstract:
A demethanizer employing C3, C4 and C4+ hydrocarbons as absorbents can be employed in a methanol to olefin process to reduce both operating and capital costs in comparison to a convention process which employs only cryogenic distillation to remove methane and other low boilers from a light olefin process stream. By reducing the use of propane, the size and operating costs of the C3 splitter can be reduced thereby providing an economic advantage over conventional applications.

Claim (Index 2):
The system of  claim 1 , further comprising:\n a deethanizer receiving an effluent of the demethanizer.
