大型甲醇合成气及循环气压缩机组选用总结

摘要

The problems and the ideas in the design and manufacture of the methanol syngas and recycle gas compressor unit to Shenhua Xinjiang 680 KTA Coal Based New Materials Project were mainly summarized connecting with the problems during the operation in the domestic same type equipment.It was mainly analyzed why the power of the compressor could be overload, the influence from the paraffin of process on the compressor, how to improve the reliability of dry gas seal, how to prevent freeze for the air cooler of the turbine.Combining with the proposals of the process package business, the solutions of Xinjiang project were provided.It would provide the reference for the domestic same type equipment designing and selection and operation.%论文重点总结了神华新疆68万吨／年煤基新材料项目甲醇合成气及循环气压缩机组在设计、制造中存在的问题，并结合国内同类型设备在运行中存在的问题，重点分析了压缩机功率超负荷的原因；工艺气中石腊对压缩机的影响；如何提高干气密封可靠性；透平空冷如何防冻的问题，结合工艺包供应商的建议提出新疆项目的解决思路，为以后类似装置的设计选型及生产运行提供参考。
