摘　　要：建立了管式裂解炉的反应传热模型 ,以描述二氯乙烷裂解制氯乙烯单体的工业过程。进一步 ,以炉膛内的分区温度为控制变量 ,产物氯乙烯单体的收率最大为目标函数 ,建立了裂解炉的操作优化模型。采用序列二次规划法求解 ,得到了不同的二氯乙烷进料流率下最优的炉膛分区温度操作值。并由此提出了在裂解炉炉膛采用降温序列的分区操作法 ,以及裂解炉炉膛高温辐射区、降温辐射区。A reaction heat transfer model of the radiation chamber in an industrial scale cracking furnace has been proposed for production of vinyl chloride monomer (VCM) from 1,2 dichloroethane (EDC). And an optimization scheme to maximize the yield of VCM was then presented by dividing the radiation chamber into several sections and controlling the temperature of each section independently. The optimal temperature profiles inside the furnace at different EDC feeding rates were calculated by means of successive quadratic programming. A novel operation model was put forward with the feature of a decay cascade of temperature series inside the furnace. Meanwhile a methodology of cracker structure synthesis was given to combine three sub zones of high radiation temperature, lower radiation temperature and convection heat transfer in upper of furnace to maximize heat recovery and material conversion.
