Natural gas consists of various hydrocarbons with different molecular weights, including Ethane, Propane, Butane, and other heavier hydrocarbons. In the natural gas processing and separation unit, hydrocarbon components are separated using distillation columns such as De-Ethanizers, De-Propanizers, and De-Butanizers, along with similar equipment. The removal and separation of these components not only creates economic value through the sale of the recovered products but also plays an important role in controlling the hydrocarbon dew point of natural gas. NGL separation can be carried out using various methods, including absorption and Cold Box technology. Currently, the latter method is more widely applied due to its associated advantages.
