【摘要】 煤制烯烃技术的发展使得煤基乙烯法PVC工艺成为一种选择,通过对不同工艺全流程碳排放量(直接碳排放+间接碳排放)进行计算分析,认为相对于煤基乙烯法PVC(纯锅炉模式)生产工艺,电石法和煤基乙烯法PVC(锅炉+燃气轮机模式)的碳排放较低,而由于后者不存在汞污染问题,从CO2减排、能源转化效率、成本和清洁化生产等综合角度来讲具有一定的优势.更多还原

【Abstract】 The development of coal to olefin technology made coal-based ethylene process producing PVC become an option. In this paper, different technology processes of carbon emissions (direct and indirect carbon emissions) were calculated and analyzed. Compared to coal-based ethylene PVC (pure boiler model) production process, calcium carbide and coal-based ethylene PVC (boiler+gas turbine mode) show lower carbon emissions. In addition, little mercury pollution was produced by the latter, so that there was certain advantage in the comprehensive degree of CO2 emission reduction, energy conversion efficiency, cost and clean production etc.更多还原
