Abstract:

 A static simulation model of overall process for a light hydrocarbon recovery plant were  developed, which could  not only improve the yield, save energy and reduce loss,  but could also ensure safety in production.The distillation units were modeled based on CAPE-OPEN technology, the parameters of the process were analyzed by simulation and emendated according to the actual data. The correlative process parameters which could  meet the requirement of improving the ethane yield were simulated and evaluated by sensitivity analysis. The process parameters of the demethanizer were optimized. The results showed that the simulation data were in good agreement with the plant data, and the optimum process parameters could  be applied to guide the actual industrial production.
