摘要:

介绍了乙烯装置原料的构成和发展趋势,认为裂解原料逐渐向轻质化发展。结合几种代表性的裂解原料的裂解条件和裂解气组成,重点分析了裂解气组成变化对乙烯装置各系统工艺及设备的影响。由于每套装置的原料性质、各种原料的比例、采用的工艺技术和设计余量均不相同,且当装置原料发生变化时各系统和设备的负荷变化比例也不相同,因此,要想判断原料变化后乙烯装置各系统的适应情况,必须对该装置的各系统和设备进行针对性核算。

Abstract:

The steam cracker feedslate and its developing trend are introduced. It is considered that the cracking feedstock has become lighter and lighter. The impact of changes in feedslate on the process and equipment of different systems in ethylene plant is analyzed based on the cracking conditions and cracking gas composition of several typical cracking feedstock. The feedstock properties, the proportion of each feedstock, the process technology and the design margin are different among ethylene plants, and the load change proportion is different among systems and equipment when the cracking feedstock changes. Therefore, calculation shall be done for the systems and equipment in ethylene plant to judge the adaptability of each system to the changes in feedstock. 

Key words: ethylene, steam cracking, cracking feedstock
