摘要
综述了国内外氢气资源优化技术的进展情况,指出了现有方法存在的问题,提出了技术的未来发展方向:夹点方法以图形化的表现形式对系统瓶颈进行呈现,计算过程简单、易懂,但其忽略了压力、杂质等因素对氢气网络的影响,数学规划算法通过系统建模进行详细的模拟计算,其假定氢油比和氢分压的微量变化及杂质因素不会对装置操作和产品分布产生影响,在装置用氢条件变化不大时可实现氢气系统的效益最大化,而当装置用氢条件发生较大变化时这种假设无法成立,对加氢装置进行反应动力学建模工作可以克服这种缺陷。
This paper reviews the progress of hydrogen resource optimization technology at home and abroad,points out the problems of existing methods and proposes the future direction of technology development:pinch method presents system bottlenecks in graphical forms,the method is simple and easy to understand,but it ignores the effect of pressure,impurities and other factors on hydrogen networks;mathematical programming method details system modeling simulation to maximize the hydrogen system by assuming that the swinging in small range of the hydrogen oil ratio and the hydrogen partial pressure has no effect on the operation of the device and product distribution,this assumption is established under the situation that the hydrogen condition has a small change,but not when hydrogen condition changes significantly,however,kinetic modeling can conquer this shortcoming.
