Henan Hebi Hongmeng New Materials Co., Ltd.’s project for producing 5,600 tons of electronic chemicals per year and 10,000 tons of NMP through recycling

Thread Content

Recently, the annual production project of 5,600 tons of electronic chemicals and 10,000 tons of NMP for recycling at Henan Hongmeng New Materials Co., Ltd. was announced on relevant websites. This project, with a total investment of 456 million yuan, is located in the Moushan Industrial Park in Shancheng District, Hebi City, and will involve the construction of an electronic-grade sulfur dioxide production line as well as NMP recycling facilities. According to the public information, the project will employ two entirely different process routes, one for each of the two products. The electronic-grade sulfur dioxide production line will follow the process flow of \"sulfur combustion – sulfur recovery – conversion – sulfur removal – purification – refinement – condensation\", ultimately enabling the bottled and sale of sulfur dioxide. The regeneration and recycling of NMP employ multi-stage distillation technology; through the processes of \"primary dehydration – secondary dehydration – distillation\", crude NMP is converted into high-purity products that can be reused. This patented technology separates liquids from waste gases by condensing the exhaust gas from the atmospheric and vacuum distillation tower, and then achieves efficient recovery of NMP through multiple processes such as heat exchange cooling and rotary wheel adsorption/desorption. The main equipment of the project includes waste heat boilers, sulfur incineration furnaces, desulfurization reactors, sulfur separation tanks, dehydration towers, refining towers, etc., which form a complete production system. Project Overview: Project Name: Project for the annual production of 5,600 tons of electronic chemicals and 10,000 tons of NMP through recycling. Developer: Henan Hongmeng New Materials Co., Ltd. Location: No. 8 Mouxing Avenue, Moushan Industrial Park, Shancheng District, Hebi City. Nature of the project: New construction. Investment amount: Approximately 456 million yuan. Scale and scope of the project: The project covers an area of 39,790.78 square meters; it makes use of the existing production workshops, utility facilities, auxiliary systems, and tank areas available at the company to produce 5,600 tons of electronic chemicals and 10,000 tons of NMP per year. The production capacity for electronic-grade sulfur dioxide is 5,600 tons per year, while the production capacity for NMP is 10,000 tons per year. Main equipment: waste heat boiler, sulfur incinerator, desulfurization reactor, sulfur separation tank, dehydration tower, purification tower, etc. Process flow: sulfur combustion–sulfur recovery–conversion–desulfurization–purification–refinement–condensation–packing sulfur dioxide for sale ； Crude NMP — primary dehydration — secondary dehydration — distillation — NMP is packaged and sold. Henan Hongmeng New Materials Co., Ltd. is located at No. 8 Muxing Avenue, Moushan Industrial Park, Shancheng District, Hebi City. With a total land area of 39,790.78㎡, the company is mainly engaged in the manufacturing of specialty chemical products, the production of synthetic materials, as well as the research, development, production, and sales of related processes and equipment.
