安徽安庆市鑫富化工有限责任公司坐落于安庆市大观区凤凰循环经济工业园,由浙江鑫富药业股份有限公司独资建设。2011年3月27日凌晨,该厂氯化工段开始在3号低温反应釜进行氯化试剂的生产作业。该作业工艺流程是,在低温反应釜投入二甲基甲酰胺(企业出于技术保密考虑,将该物料代称“T11”),之后滴加氯化亚砜(代号“T13”)。经过保温和真空浓缩之后,再通入氮气破除釜内真空,并补加二甲基甲酰胺进行降温。在工艺流程设计上,该企业将作为反应釜清洗剂的甲醇管道与作为反应物料的二甲基甲酰胺管道相邻并行,最后合并通过同一个阀门进入反应釜。这种工艺设计就为事
Anqing City, Anhui Xin Fu Chemical Co., Ltd. is located in Anqing City, Daguanyuan Phoenix Circular Economy Industrial Park, Zhejiang Xin Fu Pharmaceutical Co., Ltd. wholly-owned construction. In the early morning of March 27, 2011, the chlor-alkali section of the plant started the production of chlorinated reagents in No. 3 low-temperature reactor. The operation of the process is that the low temperature reactor into dimethyl formamide (for technical reasons confidential business, the material is called “T11 ”), followed by dropwise addition of thionyl chloride (codenamed “T13”) . After heat preservation and vacuum concentration, then purge the kettle with nitrogen to vacuum and add dimethylformamide for cooling. In the process design, the company will be as a reactor cleaning agent methanol pipeline and as the reaction of dimethylformamide pipe adjacent to parallel, and finally merged through the same valve into the reactor. This process design matter
