YHS-200溶剂在大庆石化气化装置的开发及应用

Development and industrial application of desulphurization and decarbonization solvent YHS-200 in gasification unit of Daqing Petrochemical Company

介绍了YHS-200溶剂的开发及其在大庆石化气化装置的首批工业应用情况。结果表明:YHS-200溶剂投用后,不但装置的净化系统操作平稳,无发泡迹象,而且溶剂的再生情况良好,可降低生产成本79.0万元/a;当装置满负荷生产时,经质量分数为25%的YHS-200溶剂脱硫脱碳处理后,合成气中CO2,H2S,COS的体积分数分别为0.06×10-2,小于0.1×10-6,小于0.1×10-6,系统胺损耗量为4 915 kg/a,均符合工艺技术合同规定的小于0.1×10-2,4×10-6,13×10-6和15 t/a的相应指标,满足了生产需要;该溶剂的凝固点低,在冬季补加时不需要消耗蒸汽,适合于大庆石化等寒冷地区的工厂使用。该溶剂的工业应用,为气体净化技术提供了新方法。

The development and the first industrial application of desulphurization and decarbonization solvent YHS - 200 in gasification unit of Daqing Petrochemical Company was introduced, The results showed that after solvent YHS -200 was used, the operation of purification system was stable, no foaming phenomenon occurred, the regeneration of the solvent was better and the production cost was reduced by 0.79 million yuan per year. Under the condition of production load of 100% and being treated by solvent YHS -200 of mass fraction 25% , the volume fractions of CO2, H2S, COS in synthesis gas were 0.06 × 10^-2, less than 0.1 × 10^-6 , lessthan 0.1 × 10^-6 respectively, and the wastage of amine in the system was 4. 915 t/a. These could meet the needs of corresponding indexes in the operation technology contract. Because of the lower freezing point of the solvent, it would not need to consume the steam for heating and was suitable for the factories in the cold areas. The industrial application of solvent YHS -200 offered a new method for gas purification technology.
