Research on Crude Oil Stabilization Process Simulation and Parameter Optimization Technology
Crude oil stabilization is a process technology that separates and recovers light components from crude oil,which can effectively reduce evaporation losses during the crude oil gathering and trans-portation process.In order to reduce the comprehensive energy consumption of crude oil stabilization and improve product economic benefits,a comparison is conducted on the operating conditions,in-vestment costs,energy consumption analysis,product quality,and other aspects of different crude oil stabilization processes through the analysis of the current situation of crude oil gathering and transporta-tion.Based on on-site production practice,the negative pressure flash evaporation process technology is selected as the research object,and Aspen HYSYS is used for modeling and analysis.The correlation and variation laws of parameters such as stable pressure,stable temperature,stable depth,and top dis-charge of the negative pressure flash evaporation technology are studied.The comprehensive energy consumption,operating costs,and economic benefits are evaluated.Combined with the boundary conditions established by equipment capacity and product quality,the optimal operating parameters are determined based on the variation law of parameters.By modeling and calculating with Aspen HYSYS,reasonable operating parameters can significantly reduce heat loss during the stabilization process,there-by reducing comprehensive energy consumption,improving product output rate,achieving the goal of cost reduction and efficiency increase,and achieving energy-saving,efficient,and cost-effective op-eration of the crude oil stabilization system.This has certain guiding significance for the adjustment and optimization of the same type of crude oil stabilization process.
