- 摘要:
为实现油气田开发进一步节能降耗,促进油气田企业高质量发展,在西部某油田轻烃回收厂冷却系统工艺流程及能耗分析的基础上,开展天然气增压机组余热回收利用方案研究。余热回收利用方案能够同时解决轻烃回收厂夏季冷却系统制冷和冬季厂区建筑供暖问题,在不影响生产工艺流程的前提下实现节能降耗。余热回收利用后可为轻烃回收厂冷却系统每年节约用电1 226×104 kWh;冬季为厂内建筑供暖，提供生活热水，除盐装置供热，每年节省燃料气消耗144.5×104 m3;每年可节约燃料消耗折合标煤2 773.2 t,CO2减排7 377 t；10年现值节约4 964.2万元。余热回收利用方案为该地区油气地面处理工艺进一步优化提供指导。
Based on the analysis of cooling process and energy consumption of light hydrocarbon recovery plant in a western oilfield, a waste heat recovery and utilization scheme of the natural gas compression system is proposed in this paper.The proposed scheme can solve the problems of cooling system refrigeration in summer and building heating in winter, and realize energy saving and consumption reduction without affecting the production process.The optimal design scheme can save 1226×104kWh of power consumption per year and a 144.5×104m3fuel gas consumption is saved for building heating, domestic hot water and desalinization unit heating in winter.The annual fuel consumption saved is equivalent to standard coal of 2773.2t, carbon dioxide emission reduction by 7377t, and present value saving of 49.642 million yuan in 10 years, which provides guidance for further optimization of oil & gas surface process.
