3.1Mt/a连续重整装置热态考核实践与优化建议OA

Addressing the technical challenges faced by domestically produced large-scale continuous reforming units during large-scale commissioning,this article takes a 3.1Mt/a ultra-low pressure continuous reforming unit from a certain company as the research subject.It conducts a systematic study on the preparation work and commissioning process of the hot state assessment of the reaction-regeneration system.It also elaborates on the process flow,technical parameters,and control points of the hot state assessment.Furthermore,it deeply analyzes the causes and targeted solutions to key issues that arose during the assessment process,such as insufficient flow of the reduction electric heater and packing falling off in the regeneration gas alkali scrubber mixer.Through the hot state assessment,the consistency between the displacement of high-temperature equipment in the reaction system and its design is verified.Meanwhile,in response to issues encountered in similar units,optimization measures such as improving the insulation materials of the transfer line and enhancing the design of the catalyst pipeline system are implemented.This provides experience for the large-scale construction management and commissioning of similar continuous reforming units and lays a foundation for the long-term stable operation of subsequent units.
