The first large-scale equipment for the amide and nylon new materials project of Hubei Sanning Chemical Co., Ltd. was hoisted in place Author/Source: Chemical Network Coal Chemical Industry Date: 2023-04-07 Click rate: 80 Recently, the first large-scale equipment for the amide and nylon new materials project of Hubei Sanning Chemical Co., Ltd. was hoisted in place. At the construction site of the amide and nylon new material project, two large cranes worked together to successfully lift the furnace shell of the sulfur incinerator waste heat boiler of the sulfuric acid plant into place. The furnace shell is 14 meters long and consists of 95T and 150T two-section shells. It is the main facility for heat energy recovery. It is reported that this waste heat boiler hoisting is the first large-scale equipment hoisting in the project. After the hoisting is in place, the installation of steam drums, safety devices and pipelines will be started immediately. In order to ensure smooth hoisting, the project department assigned dedicated personnel to take charge from the beginning of large-scale transportation to achieve unified coordination from transportation routes to on-site hoisting. In early March, the park coordinated the upgrade of main pipeline corridors, planned water and land transportation routes, and went all out to strive for excellence and efficiency. Hubei Sanning Chemical Co., Ltd.'s amide and nylon new material project is located in Yaojiagang Chemical Park, Zhijiang City, Hubei Province, with a total budget investment of 14.5 billion yuan, mainly including: 400,000 tons/year caprolactam project: including 1 million tons/year sulfuric acid unit, 560,000 tons/year hydrogen peroxide (50%) unit (the first phase: 400,000 tons/year, the second phase: 160,000 tons/year) 400,000 tons/year caprolactam supporting ammonium sulfate unit equipment and 2 sets of 200,000 tons/year ammonium sulfate extrusion granulation; 400,000 tons/year polyamide differentiated new material spinning project: including 400,000 tons/year polymerization unit (first phase scale: 333,000 tons/year), 20 10,000 tons/year nylon 6 spinning (Phase I scale: 60,000 tons/year); 200,000 tons/year nylon 66 project: including 480,000 tons/year cyclohexanol unit (Phase II: 320,000 tons/year), 465,000 tons/year * * Devices (Phase II: 135,000 tons/year), as well as 240,000 tons/year adipic acid, 100,000 tons/year adiponitrile, 100,000 tons/year hexylamine, 200,000 tons/year nylon 66 and other devices. The amide and nylon new material project is another tens of billions-level project after Hubei Sanning Chemical Co., Ltd. transformed from traditional chemicals to new chemical materials and successfully completed trial production of 600,000 tons of ethylene glycol. Sanning's synthetic ammonia raw material structure adjustment and co-production of 600,000 tons/year ethylene glycol project is based on the Sanning Company's urea plant and Tiantian Company's synthetic ammonia production capacity of 520,000 tons/year. On the premise that the production capacity does not increase, the urea plant and Tiantian Company's synthetic ammonia units and downstream urea and ammonium bicarbonate units that use anthracite as raw materials and use atmospheric intermittent fixed-bed gasifiers, atmospheric desulfurization, and high-pressure ammonia synthesis will be eliminated. The total investment of the project is 10 billion yuan. The new project will use Shenhua high-quality coal as raw material to produce 400,000 tons/year of ethylene glycol and 520,000 tons/year of synthetic ammonia; and use sulfur as raw material to produce 800,000 tons/year of industrial-grade sulfuric acid.
