焦炉煤气制甲醇合成系统补碳的研究

介绍了焦炉煤气制甲醇的工艺原理。以唐山中润煤化工有限公司为例,分析了甲醇合成工艺中普遍存在的合成气中CO2含量不足的原因及后果。为解决这一问题,提出通过外购液态CO2,并通过CO2气化装置将其气化对甲醇合成工艺进行补碳的措施。从7个方面介绍了再补碳过程中的注意事项。通过这一措施,可以显著提高甲醇产量和甲醇合成系统补碳的经济效益。 Introduce the principle of methanol pyrolysis from coke oven gas. Taking Tangshan Zhongrun Coal Chemical Co.,Ltd.,for example,analyse the reasons for inadequate CO2 supply and the consequences in methanol pyrolysis process. To resolve this problem,purchase liquid state CO2,which is then gasified by gasification equipment. Fill the gas state CO2 into methanol pyrolysis system. Indicate the matters needing attention from seven aspects. The results show that,the method can improve the methanol yield and economic benefits of methanol pyrolysis system
