Group 1 - The article discusses the environmental impact assessment public announcement for Cangzhou Xuyang Chemical Co., Ltd.'s new nylon material project, which aims to produce 230,000 tons annually [2] - The project will include the construction of four production lines and the acquisition of 22 major equipment units, including reactors and extraction towers [2] - The existing projects of Cangzhou Xuyang Chemical include various production capacities for caprolactam, cyclohexanone, and other chemical products, all equipped with environmental protection facilities to ensure compliance with pollution discharge standards [2]

Core Viewpoint - The successful commissioning of the 40,000 tons/year ultra-high molecular weight polyethylene project by Pujie Energy Chemical marks a significant advancement in modern coal chemical integration, utilizing surplus ethylene and hydrogen from existing facilities to produce high-performance polyethylene products for various applications [1]. Group 1: Company Overview - Pujie Energy Chemical was established in November 2008, co-funded by Shaanxi Coal and Chemical Industry Group and China Three Gorges Corporation, focusing on the deep integration of traditional coal and petroleum chemical industries [1]. - The company’s methanol production capacity is 1.8 million tons per year, with a DMTO capacity of 680,000 tons and additional capacities for polyethylene and polypropylene [1]. Group 2: Project Details - The newly launched project utilizes surplus ethylene and hydrogen from the MTO and olefin separation units, employing hexane as a solvent to produce ultra-high molecular weight polyethylene [1]. - The project aims to cater to manufacturing needs in sectors such as sheet materials, bulletproof vests, ropes, pipes, and custom parts [1]. Group 3: Production Enhancements - The MTO and olefin separation unit enhancement project is expected to increase processing capacity by 30%, allowing for an annual production of 848,800 tons of olefins, with an additional 159,300 tons of olefins produced annually [1].

【DT新材料】 获悉， 近期，台州市生态环境局发布了 浙江清和新材料科技有限公司 年产60吨聚酰亚胺系列产品、1110吨氢化系列产品及500吨糠 酸等产品技改项目 环境影响报告书受理的公示。 据悉，该项目 总投资 1200 万元， 建设地址在浙江省仙居经济开发区，新增的生产线包括 130t/a2,2'-双[4-(4-氨基苯氧基)苯基]丙烷、500t/a 1,3-环 己二胺、200t/a 1,4-环己二胺、5t/a 聚酰亚胺 QPI-SL20、10t/a 聚酰亚胺 QPIP330、20t/a 聚酰亚胺 QPI-P350 。同时，本项目对现有的反式-4-氨基 环己醇、糠酸的生产线，以及已报批但未建设的 QPI-P280 进行技改，对其生产工艺进行调整，并将糠酸产能由 100t/a 调整为 500t/a，反式-4-氨基 环己醇产能由 200t/a 调整为 280t/a，QPI-P280的产能由 60t/a 削减至 25t/a。 此外，本次技改过程中对部分现有产品的产能进行调整，而保持工艺不变。具体包括：①YS20 产能由 40t/a 削减至 30t/a；②QPI-P460 产能由 30t/a 削减至 20t/a；③ ...
