摘要
通过对炼厂干气、丙烷作乙烯裂解原料及烯烃歧化技术生产丙烯的经济性分析,认为炼厂干气是很好的裂解原料,具有投资低、消耗低的特点,并指出丙烷作乙烯原料合适的价格临界点以及烯烃歧化技术制取丙烯是适应今后丙烯的发展趋势,避免与中东低乙烯成本进行竞争的有效途径。
After discussing economics on using refinery dry gases and propane as fee dstocks of steam cracker and using olefin dispro-portionation technology to produce propylene,this article concludes t hat refinery dry gases are good crack ing feedstocks and have ad-vantages of low investment and consu mption.The article also points out t hat the appropriate price critical p oint of using propane as ethylene feedstock and using olefin disproportionation technology to p roduce propylene is an effective way adapted to future propylene development trend and to avoid competing with low cost ethylene in middle east.
