中文摘要：
石化园区化肥厂、乙烯厂等富氢气体送往炼油厂,能够缓解炼油厂的氢气亏缺,因而石化园区厂际氢气系统优化具有重要的意义。本文构建了石化园区厂际提纯回用氢气系统超结构模型,以年度化总费用为目标函数,建立优化的数学模型,使用商业优化软件GAMS平台建模,用DICOPT作为求解器。对某石化园区的氢气系统进行了优化,结果表明,总的年度化费用比现行的系统降低了33.1%。
英文摘要：
Hydrogen-rich gas from fertilizer plants and ethylene plants can be sent to refinery in a petrochemical complex. It can alleviate the deficit of hydrogen in refinery. Thus the optimization of inter-plant hydrogen network in petrochemical complex is important. A superstructure of inter-plant hydrogen network with purification reuse is constructed. The corresponding mathematical model with the total annualized cost as objective function is proposed and the commercial optimization software GAMS is utilized to solve the problem with DICOPT as a solver. The hydrogen network of a petrochemical park is optimized. The results shows that the total annual cost can be reduced by 33.1% comparing to the current hydrogen network.
