摘　　要：主要研究通过合理分配装置输出,来达到流程能耗最低的问题。上海某煤化工企业的甲醇生产流程拥有多套生产装置,但现行的生产流程中,某一上游装置只固定为某一下游装置提供输入,而某一下游装置也只接受某一上游装置的输出,这使得能耗固定且无法达到最优。针对这种情况,为降低企业甲醇生产流程的能耗,结合这些装置的直接能耗系数,做到合理地分配上游装置的输出,为下游某些装置提供输入(一个装置可为下游多个装置提供输入),来寻找能耗最低的一套生产方案。因此,生产优化问题可概述为:基于煤化工企业MES系统提供的数据,在装置连接关系一定、产品质量以及装置生产能力等约束条件的制约下,建立生产调度优化模型,来实现总能耗最低的目标。最后,通过比较煤化工企业当前的实际生产状况以及该优化模型的仿真结果,来说明优化模型的有效性。There are lot of equipment within the Methanol manufacturing flow in a Coking and Chemical company.Its upstream equipment can only supply input for one specific downstream equipment,and one downstream equipment can only accept the outcome of one fixed upstream equipment.It leads to the un-optimal energy consumption.In fact,based on the direct-consuming matrix,we can find that the upstream equipment can rationally supply input for many downstream equipment to form a lowest energy consumption workflow,which is the issue of optimization.Aimed at finding a least-energy-consumption workflow,we establish an optimization model,constrained by fixed flow sequence,production quality,equipment producing capability and etc,to lower the energy consumption of this company.By comparing the present status of the company and the simulation result based on the model constructed,we find that the model can be an effective guidance to real production.
