Demethanizer
A demethanizer is a distillation column used in natural gas processing to separate methane (C1) from ethane and heavier hydrocarbons (C2+). It is a key unit in gas processing trains that aim to deliver pipeline-quality gas while recovering natural gas liquids (NGLs). The column operates on the principle of volatility differences, using a reboiler to provide heat and a condenser to remove heat, establishing a methane-rich overhead and a C2+-rich bottom.
The feed to a demethanizer contains methane, ethane, propane and heavier components at elevated pressure. Through
In many plants the demethanizer is part of a larger sequence that may include a de-ethanizer or
Demethanizers are widely used in natural gas conditioning and LNG supply chains, contributing to gas quality
