摘要
对大庆年产30万吨乙烯装置的石脑油裂解炉,提出了裂解深度和选择性的计算机控制数学模型。它由静态的前馈关联式和参变量的动态补偿两部分组成。裂解炉运转周期预测和平均烃分压构成前馈关联式的核心,裂解炉的动态特性则根据现场测试数据确定。将建立的运转周期和产率模型进行实际检验,与现场生产数据吻合较好。
This article presents a computer-controlled mathematical model of severityand selectivity for naphtha cracking furnace of Daqing 300000 metric ton/yearethylene plant.It consists of static feedforward correlations and dynamic com-pensation of parametric variables.Estimation of running period and average hy-drocarbon partial pressure on cracking furnace form the core of the static feed-forward correlations.Dynamic properties of cracking furnace are tested directly inthe plant.We find that the calculated running periods and the yields of productsconform with plant data satisfactorily.
