产品介绍 ( Product Presentation )


Natural gas deethanizer is a rectification tower that used for separating ethane(include lighter components) and propylene(include heavier components) in the cryogenic separation of cracking gas.


There are ethane and lighter components(such as ethylene,methane) on the tower top,there are propylene and heavier components on the tower bottom.


Natural gas deethanizer is a part of Ⅱ/D2 category of vessel.
