【摘要】：经济环保的渣油加氢工艺技术已经是各炼油企业提高经济效益的首选。本研究以我国自行开发的3.9 Mt/a固定床渣油加氢工艺技术在上海石油化工股份有限公司的工业应用为背景,全面采集该装置三个运行周期的工业运行数据,分析影响渣油加氢装置运行周期的众多因素及对策,包括催化剂性能、产品质量、能耗、设备、操作影响、装置安全生产的因素、存在的问题和相应的改进措施等。RHT技术在上海石化的工业应用表明,中石化石科院研发的第三代RHT系列催化剂具有较低的失活率,较高的脱硫、脱金属和脱残炭活性。在保证长周期安稳运行的前提下,渣油加氢装置采用更优化的工艺参数可为下游的催化裂化装置连续提供低硫、低残炭、低金属的加氢渣油原料。通过对装置三个周期运行过程中发现的工艺操作及设备问题分析及应对措施的实施,实现了装置的安稳运行,保证了加氢渣油满足下游催化裂化原料的要求,降低了装置能耗,也为装置未来的运行及检修打下了良好的基础。工业应用的成果将对于提高渣油加氢技术整体水平和指导同类装置的运行起到重要作用。
[Abstract]:The economic and environmental protection residue hydrogenation technology is to improve the economic benefits of the oil refining enterprises preferred. In this study, our self-developed 3.9 Mt/a fixed bed residue hydrotreating technology in industrial application in Shanghai petrochemical Limited by Share Ltd as the background, the industrial data acquisition of the overall device three operating cycle, analysis of many factors the operation of hydrogenation device cycle and countermeasures, including the catalyst performance, product quality, energy consumption, equipment operation, effect factors, device of production safety, indicates the existing problems and corresponding improvement measures of.RHT technology in industrial application in Shanghai Petrochemical Company, the third generation of RHT series catalyst developed by RIPP Sinopec has the deactivation rate low, high desulfurization, demetallization and decarbon activity. Under the premise of ensuring safe and stable operation of long period, hydrogenation device adopts the process of optimization of the parameters The number of FCC unit downstream of the continuous supply of low sulfur, low carbon residue, low metal hydrogenation residue feedstock. Through the implementation of process operation and equipment problems found the device three cycles of operation in the process of analysis and countermeasures, to achieve safe and stable operation of the plant, ensure the residue hydrotreating of FCC feedstock to meet downstream the requirements, reduce the energy consumption of the device, but also for the future operation and maintenance of the device has laid a good foundation for industrial application. The results will be to improve the overall level of residue hydrotreating technology and similar equipment operation play an important role.
