通辽明州化工40kt/a硫酸钾装置技改总结

Technical Reform on 40 kt/a Potassium Sulfate Plant in Tongliao Mingzhou Chemical Co.,Ltd

通辽明州化工有限公司针对40 kt/a曼海姆法硫酸钾装置产量低、质量不达标、炉底经常漏酸、反应温度低、氯化氢气体外泄严重等问题,对装置反应系统、加热系统、吸收系统、上料系统等设备进行了改造,并对部分工艺进行了改进。技改后,装置产量达到设计能力,质量达到国家标准,消耗降低,操作环境得到改善。

Against the problems of low capacity, low quality, acid leaking from reactor bottom, low reacting temperature, hydrogen chloride leaking etc., exposed in 40 kt/a Mannheim potassium sulfate plant, Tongliao Mingzhou Chemical Co., Ltd had made reform and revamp on the equipments in reacting system, heat system, absorbing system and feed system, partially improved the process. After reforming, the production capacity was raised up to design target, the quality of products met GB standard, the production cost was reduced, the operating environment was improved.
