Natural Gas Processing
Raw natural gas typically consists primarily of methane (CH4) and ethane (C2H6) and also contains
- The recovered NGL stream is processed through a fractionation train consisting of up to five distillation towers in series: a demethanizer, a deethanizer, a depropanizer, a debutanizer and a butane splitter.
- In the debutanizer column C3 (propane) and C4 (butane) are removed as overheads from the naphtha stream.
