摘　　要：随着加氢装置的广泛应用,炼化企业的氢气系统的管理与优化已经成为实现节能减排、降本增效的有效手段。在综述了氢夹点分析、数学规划等氢气网络优化技术最新进展的基础上,介绍了中国石化抚顺石油化工研究院开发的炼油加氢装置与全厂氢气系统的集成优化解决方案。该方案将加氢反应动力学模型与全厂氢气网络优化相结合,充分考虑了临氢装置原料、工艺条件和产品质量要求,从根本上解决了装置用氢变化后无法判断模拟数据与实际运行数据误差大小的问题;另外,该方案将装置用氢变化所带来的产品分布收益加入到目标函数中,从而实现了包含油品收益在内的炼厂收益最大化。某石化企业应用案例表明,实施该解决方案后,可在保证加氢装置优化操作、稳定长周期运转的同时,实现氢气梯级利用、轻烃资源的有效回收,氢气利用率提高了10%,经济效益显著。With the wide application of hydrogenation units ,optimizing the management of the hydrogen system has become an effective approach to saving energy,reducing emission,cutting cost and increasing efficiency for an oil refining company.Based on an overview of latest advances in hydrogen network optimizing technolo- gy,such as hydrogen pinch point analysis and mathematical modeling,this article describes the solution to op- timized integration of refinery hydrogenation units and the hydrogen system at the refinery level ,developed by the Sinopec Fushun Research Institute of Petroleum and Petrochemicals.By combing hydrogenation reaction dynamics models and optimized whole-factory hydrogen network,giving full consideration to the feedstock,pro- cess conditions and product quality requirements for hydrogenation units ,this scheme offers a fundamental so- lution to the problem of inability to judge the size of error between simulated data and actual operational data after a change in hydrogen use of a hydrogenation unit.In addition,the product distribution incomes re- sulting from a change in hydrogen use of the unit can be put into the objective function to maximize refin- ery incomes,including incomes from oil products.The application in a petrochemical company shows that the solution enables the company to achieve a gradient utilization of hydrogen and effective recovery of light hy- drogen resources while ensuring optimized,stable and long-time operation of hydrogenation units.As a result, the hydrogen utilization rate of the company increased by 10%.
