摘要
介绍了将炼厂回收干气作为乙烯裂解原料的方案,用SPYR0软件模拟计算了以石脑油、芳烃混合干气为裂解原料的裂解气组成,对这两种原料利用方案的经济性进行了分析和比较。结果表明,与石脑油相比,用炼厂干气作为乙烯装置裂解原料,乙烯、丙烯收率显著提高,可大幅增加经济效益。
The scheme of recycling dry gas of refining plant for using as ethylene cracking material was introduced, analogue computations were made with SPYRO software on the composition of cracking gas produced with naphtha and aromatics blended dry gas respectively,and analysis and comparison were made on economies of the two schemes. Result showed that comparing with naphtha,the yields of ethylene and propylene in cracking products were much greater with aromatics blended dry gas as material.
