摘　　要：炼油厂的全流程规划设计需要完善的全局资源优化计算予以支持。采用S-GROMS软件设计12.0 Mt/a炼油厂,建立了炼油厂全流程模型,通过松弛分支定界非线性优化算法实现了全流程优化,并对重油加工工艺条件、产品方案、非线性调合及不同价格体系下的最优加工路线进行了优化测算。结果表明,当原油价格体系处于40~60美元/桶时,采用全加氢方案最大化生产化工原料的炼油厂具有更好的经济效益,吨油税后利润可达373元;当原油价格体系达到80美元/桶时,由于成品油的边际效益超过乙烯,最大化生产汽油等燃料油的加氢-催化裂化方案具有更好的经济效益,投资回收期为10.6 a。使用非线性算法实现了大型炼油厂的全流程建模与优化。The whole process planning of the refinery needs to be supported by perfect global resource optimization calculation. This study uses S-GROMS(SINOPEC Global Resource Optimization Modeling System) to design a 12.0 MM TPY refinery. The whole process model of the refinery is established, the whole process optimization is realized through the relaxation branch and bound nonlinear optimization algorithm, and heavy oil processing conditions, product scheme, nonlinear blending and the optimal processing route under different price systems are optimized. The results show that when the average price of crude oils is between 40 to 60 dollar per barrel, the full hydrogenation scheme to maximize chemicals has better economic benefits, and the after-tax profit per ton of oil can reach 373 yuan;When the price is higher than 80 dollar per barrel, the margin benefit of product exceeds ethylene, the hydrogenation-FCC scheme to maximize fuel oil such as gasoline has better economic benefits, and the investment payback period is 10.6 years. The whole process modeling and optimization of large refineries is realized by nonlinear algorithm.
