摘　　要：在炼油厂的炼油与石化装置的生产过程中,容易产生很多富氢尾气。对尾气中氢气的回收,是全球石油化工相关科技人员的研究执点。当前对炼油厂与石化装置尾气中氢气的回收,主要采用PSA(变压吸附)法、膜分离法与深冷分离等方法,其中以PAS法更具优势与特点。以中国石化海南炼油化工有限公司(海南炼化厂)工业尾气综合利用技术研究项目为例,首先对变压吸附技术应用回收氢气的可行性进行分析;然后对回收流程与装置标定进行详细论述。最后得出结论:使用变压吸附技术能够提升氢气的利用率,回收率达到94.7%,且没有污染,同时PSA装置运行较好,产品能够满足对下游装置氢气的需求。In the normal production process of refinery and petrochemical plants,many hydrogen-rich gas tail hydrogens are most likely to be produced.In view of this,the recovery of hydrogen in the exhaust gas has been highly valued by the global academic community and related scientific and technical personnels,and has now become the academic research point.At present,the recovery of hydrogen in the tail gas of refineries and petrochemical plants mainly adopts PSA(pressure swing adsorption)method,membrane separation method and cryogenic separation,but since the PAS method has certain advantages and characteristics compared with other methods,it is of great practical significance to strengthen the application of PSA method in the recovery of refinery plant exhaust.In this paper,the feasibility of using pressure swing adsorption technology to recover hydrogen from the tail gas of refinery plant was analyzed.Then the recovery process and equipment calibration were discussed in detail.Finally,it was pointed out that the pressure swing adsorption technology can improve the utilization rate of hydrogen,the recovery rate can reach94.7%,and there is no pollution,at the same time,the PSA device can operate well,and the product can meet the hydrogen demand of the downstream device.
