毫秒炉共裂解及单独裂解乙烷技术分析

IMPROVEMENT IN ETHANE CO-CRACKING AND CRACKING TECHNOLOGY IN MSF

对毫秒炉石脑油单独裂解、石脑油与乙烷共裂解、乙烷单独裂解工况下的乙烯、丙烯收率进行比较。结果表明,以乙烷在裂解温度为870℃、汽油比为0.60及注硫条件下的单独裂解为优,乙烯收率达到40.58%(体积分数),经济效益明显。

Ethylene yields in cases of naphtha crack- ing,naphtha and ethane co-cracking and ethane cracking in millisecond furnace are compared with each other.The results show that ethane cracking at a tem- perature of 870℃,a dilution ratio of 0.60 and a con- dition of sulfur injection will obtain an ethylene yield of 40.58%(v).The economic benefit is remarkable.
