工业气体冷凝水分离装置的优化和能效调查

16th International Conference on Clean Energy (ICCE-2018)  

ABSTRACT ：Simulation of an industrial gas condensate separation unit is performed using Aspen Plus by evaluating several equations of state (EoS) from classical and advanced models, namely, PR EoS, CPA EoS, and PC-SAFT EoS. The results show that all models are capable in giving good approximation of the actual data, however, CPA EoS gives the most accurate results. The influence of reflux ratio and feed condition on product and heat duty of the plant are investigated through sensitivity analysis. It is found that, increasing the feed temperature reduces reboiler duty, however, it has insignificant effect on condenser duty. Also, higher feed flowrate increases heat duty for each splitter and air cooler. Reducing reflux ratio decreases heat duty in each splitter. Additionally, reducing the reflux ratio in second splitter will result in higher production of desired hydrocarbons. Finally, in the specified optimum conditions, the required energy reduces by more than 20%.
