Abstract:

Recovery of ethylene, an important raw chemical material, from refinery gas can effectively reduce production cost and improve profit of refineries. A new hybrid hydration and absorption process for recycling ethylene from refinery gas was designed and optimized by using Aspen Custom Modeler. Conditions at various efficiencies of ethylene recovery were optimized through operational parameters, such as oil flow rate, theoretical plate numbers, water content and temperature.

Key words: refinery gas, hydrate, absorption, simulation, optimization

摘要:

乙烯是一种重要的化工原料,从催化干气中回收乙烯,能有效地降低我国炼油厂的生成成本,提高其经济效益。采用水合物-吸收耦合新工艺,对催化干气中C2组分进行回收。应用Aspen Custom Modeler模拟软件,对该工艺流程进行了设计和模拟优化。通过对乳液用量、理论板数、水含量、操作温度等参数进行优化,得到了不同乙烯回收率下的最优操作条件。
