中国石化新闻网讯 据ICIS网站1月29日消息 周五，美国伊士曼公司宣布投资2.5亿美元，在田纳西州Kingsport的生产中心建设一个甲醇分解设施。 这家工厂也被称为分子回收设施，将利用甲醇分解法将难以回收的废聚酯塑料分解成单乙二醇（MEG）和对苯二甲酸二甲酯（DMT），伊士曼公司将使用这些中间体生产15-20万吨/年的新型聚合物。 预计今年年中动工，2022年底完工。 田纳西州政府同意推动该项目的建设。 首席执行官Mark Costa在星期五的伊士曼第四季度财报电话会议上表示，与名字不同，甲醇分解不涉及生产甲醇。 该工艺利用聚酯废料，使用甲醇和适量的能量将废料分解成中间体。 他说，这比用化石燃料生产新的MEG或DMT更节能。 此外，甲醇分解不是机械回收，这一过程是有限的，因为它只能使用非常清洁的废物原料。 另一方面，甲醇分解可以处理机械回收不能处理的废物，它可以在回收循环中“不断地、不降解地”回收这些废物。 王磊 摘译自 ICIS 原文如下： US Eastman to build $250m methanolysis project in Tennessee Eastman on Friday announced a $250m capital investment to build a methanolysis facility at its production hub in Kingsport, Tennessee. The plant, also referred to as a molecular recycling facility, will use methanolysis to break down hard to recycle waste polyester plastic into monoethylene glycol (MEG) and dimethyl terephthalate (DMT) - intermediates Eastman will use to make 150,000-200,000 tonnes/year of new polymers. Construction is expected to begin in the middle of this year, with the facility to be mechanically complete by year-end 2022. The Tennessee state government agreed to “incentivize” the construction of project. CEO Mark Costa, speaking during Eastman’s Q4 earnings call on Friday, said that contrary to its name, methanolysis does not involve producing methanol. The process takes polyester waste and uses methanol and a modest amount of energy to break the waste into its intermediates. It is much more energy efficient than producing new MEG or DMT from fossil fuels, he said. Also, methanolysis is not mechanical recycling, a process that is limited as it can use only very clean waste feedstocks. Methanolysis, on the other hand, can process wastes mechanical recycling cannot handle, and it can recycle them “constantly, with no degradation” in the recycling loop, he said. “Methanolysis really is a long-term, infinite solution, much more similar to aluminium”, he added. |
