Modelling and improving natural gas condensate process with stripping and heat integration

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.
