双套50万t/a甲醇合成装置运行总结

Operation summary of two sets of 500 kt/a methanol synthesis units

新能凤凰公司双套50万t/a甲醇合成装置采用华东理工大学开发的“管壳外冷-绝热复合式固定床催化反应器”型甲醇合成塔.通过对并联运行总结以及在实际生产过程双套并联接气的操作优化,进行甲醇合成局部流程优化、联锁变更、气量平衡操作、气体成分优化操作等技术改造,相应技术改造完成后,双系统生产更加平稳,完成年产甲醇100万t/a目标,取得较好的经济效益。

Xinneng Fenghuang Energy company's two sets of 500 kt/a methanol synthesis units using methanol synthesis tower of tubular external cooling adiabatic composite fixed bed catalytic reactor made by East China University of Science and Technology,through the summary of parallel operation and the operation optimization of double parallel connection in the actual production process,partial process optimization of methanol synthesis is carried out,interlock is optimized,gas is balanced,gas composition operation is optimized.After these technical retrofit,the double system production is more stable,the target of 1 million methanol production annually has been achieved,and good economic benefits have been achieved.
