蒸汽动力系统( Steam power system, SPS)是炼油企业的重要组成部分,针对炼油企业蒸汽动力系统设计与运行方案上存在的不合理方面,通过对蒸汽动力系统建立混合整数线性优化模型( MILP),改善部分系统结构、调整系统多周期运行方案,从而降低蒸汽动力系统的运行费用实现系统的优化。以某炼油企业蒸汽动力系统实为背景,对企业蒸汽动力系统的设计与多周期生产调度方案进行优化,并验证优化策略的有效性。
Simultaneous Optimization for Design and Operation of Steam Power System in Refinery Plant
Steam power system ( SPS ) is an important part of refinery plant. A mixed-integer linear programming ( MILP) model was established to solve the problem of design and operation of steam power system in refinery plant. The method can decrease the operational cost through improving the structure and change the operational scheme of the system. One motivation example was introduced to optimize the design and operation of system, by the comparison, it was obvious to find the effectiveness of the proposed MILP model.
