中煤陕西公司甲醇合成系统改造获突破作者/来源：陕西省石油和化学工业联合会 日期： 2020-12-03 点击率：12 11月29日，陕西省石油和化学工业联合会在西安组织召开科技成果鉴定会，对中煤陕西榆林能源化工有限公司开发的“180万吨/年甲醇合成系统产能提升关键技术开发及应用”科技成果进行评审，专家认为该技术达到国际先进水平，引领行业技术进步。 中煤陕西公司化工分公司总工程师孙宗礼介绍，该公司原设计甲醇年产能和MTO装置年消耗量均为180万吨，2014年6月装置建成投料后一直稳定运行。但由于甲醇制烯烃及后续装置设计余量较大，甲醇装置最高运行负荷只能提高到103%，无法满足后续装置生产对甲醇原料的需求，需要外购部分甲醇。 为充分发掘甲醇装置潜力提高产能，进一步节能降耗，2016年该公司提出甲醇合成系统产能提升和工艺优化研究项目，对甲醇装置关键技术展开攻关研究，2017年4月新建1台气化炉。在此基础上，针对甲醇合成反应器是甲醇系统关键设备，径向反应器内的中心管气体分布器直接影响反应器内流体均布、反应器压降、碳转化率进而影响甲醇产能，他们通过对反应器中心管的气体均布、气体分流、集流道静压降、中心管穿孔压降等深入研究，改变中心管分布器开孔率及开孔面积，率先对大型甲醇合成反应器中心管开孔率进行优化设计，提高甲醇合成反应效率，达到提升甲醇产能的目的。 以中国煤炭科工集团有限公司首*科学家徐振刚研究员为主任的鉴定委员会认为，中煤陕西公司还首次工业化试用了甲醇合成新型催化剂，提高催化剂堆密度、比表面积和合成气单程转化率，降低催化剂床层压降，节能效果明显；优化甲醇合成系统工艺技术，提出甲醇合成塔的串并联耦合优化运行模式，合成系统产能明显提升。这套甲醇合成系统产能提升关键技术创新性强，不但对该公司具有显著的经济效益和社会效益，而且对国内煤（甲醇）制烯烃企业也有较强的示范意义，建议加快在行业内推广应用。 据悉，该技术2018年9月在中煤陕西公司180万吨/年甲醇工业装置应用后，系统压降由70kPa降至20kPa，催化剂比表面积达到120m2/g，合成气单程转化率达到60%，至今连续稳定运行两年多，甲醇年产量达到215万吨，产能提升20%。2019年以来，多孔式中心管的合成反应系统等多项技术获**专利授权。
这个突破很不错，自有技术，单是这百分之二十就降低好多成本 ================== 针对甲醇合成反应器是甲醇系统关键设备，径向反应器内的中心管气体分布器直接影响反应器内流体均布、反应器压降、碳转化率进而影响甲醇产能，他们通过对反应器中心管的气体均布、气体分流、集流道静压降、中心管穿孔压降等深入研究，改变中心管分布器开孔率及开孔面积，率先对大型甲醇合成反应器中心管开孔率进行优化设计，提高甲醇合成反应效率，达到提升甲醇产能的目的。 以中国煤炭科工集团有限公司首*科学家徐振刚研究员为主任的鉴定委员会认为，中煤陕西公司还首次工业化试用了甲醇合成新型催化剂，提高催化剂堆密度、比表面积和合成气单程转化率，降低催化剂床层压降，节能效果明显；优化甲醇合成系统工艺技术，提出甲醇合成塔的串并联耦合优化运行模式，合成系统产能明显提升。这套甲醇合成系统产能提升关键技术创新性强，不但对该公司具有显著的经济效益和社会效益，而且对国内煤（甲醇）制烯烃企业也有较强的示范意义，建议加快在行业内推广应用。 据悉，该技术2018年9月在中煤陕西公司180万吨/年甲醇工业装置应用后，系统压降由70kPa降至20kPa，催化剂比表面积达到120m2/g，合成气单程转化率达到60%，至今连续稳定运行两年多，甲醇年产量达到215万吨，产能提升20%
