Summary/Abstract: In process economics, equipment cost is an important element. Equipment cost is based on the size of equipment, which depends on how much process fluid is required to be treated by the equipment. HYSYS software is widely used as a simulator to design the equipments in a process industry. In order to perform simulation in HYSYS, a thermodynamic model is chosen as a Fluid package in HYSYS. This paper focuses on equipment sizing by using two different thermodynamic models and shows that for the same material and energy requirements of process fluids, there is a wide difference in sizing results of the same equipment. Further, the economic study also shows that there is a huge difference of costs for same equipment, if two different thermodynamic models are used for sizing purposes in HYSYS. The study recommends the selection of appropriate and suitable thermodynamic model to perform process designing using HYSYS.
