Summary:[Display omitted] •Natural gas condensate stabilization process is modelled into Aspen HYSYS.•Gas condensate stabilization process is improved through heat integration.•Heat integration is envisaged to recover heat within a process.•Process control of complex process with energy integrated is performed. Fractionation has been proven to be an efficient method among different methods that can be used in stabilizing natural gas condensate. In this paper, an issue of improving a process that stabilizes natural gas condensate is raised and different process alternatives are proposed based on heat integration scenarios. The resulting process systems have reboilers that use the bottoms product and compressed overhead product to preheat the feed. Steady state process models for different case scenarios were developed using HYSYS software, and dynamic control of the optimal complex interacting systems are studied. A control structure is developed and tested using conventional PI controller.
