据盐城市环保局网站消息,2013年1月29日,盐城恒盛化工有限公司8000t/a水合三氯吡啶酚钠异地技改项目已进行了竣工环境保护验收现场监测和调查工作,该项目的建设地点位于滨海县沿海工业园,项目总投资额5000万元,其中环保投资500万元。该工艺产生的废气处理方式是蒸馏过程中产生的吡啶、2-氯吡啶、2,6-二氯吡啶、四氯吡啶、五氯吡啶废气采用三级冷冻冷凝回收后通过30m高排气筒排空。精馏过程中产生的吡啶、2-氯吡啶、2,6-二氯吡啶、四氯吡啶、五氯吡啶废气采 According to Yancheng Environmental Protection Agency website news, January 29, 2013, Yancheng Hengsheng Chemical Co., Ltd. 8000t / a hydrated trichlopiperidine sodium off-site technological transformation projects have been completed on-site monitoring and investigation of environmental protection acceptance of the project’s The construction site is located in Coastal Industrial Park of Binhai County with a total investment of 50 million yuan, including 5 million yuan of environmental protection investment. The exhaust gas generated by the process is generated by the process of distillation pyridine, 2-chloropyridine, 2,6-dichloropyridine, tetrachloropyridine, pentachloropyridine exhaust using three-stage refrigeration condensate recovery through 30m high exhaust row air. Pyridine, 2-chloropyridine, 2,6-dichloropyridine, tetrachloropyridine and pentachloropyridine generated during rectification
