Distillation is the energy-intensive separation process that recorded approximately 40% of the energy usage in the chemical and petrochemical industries. Natural gas liquids (NGL) is a product of distillation process which characterised by the multicolumn setup that leads to high heating and cooling requirements. Therefore, the main purpose of this study is to investigate the application of driving force method (DFM) with the support of the thermal pinch analysis (TPA) to enhance the energy saving of the NGL distillation process under various feed composition scenarios. The NGL distillation process in this case study comprising three types of feed composition of propane, i-butane, n-butane, i-pentane, and n-pentane, were simulated using Aspen HYSYS.
