The production process of polyester fiber includes polycondensation and melt spinning. Raw materials mainly come from petroleum pyrolysis, but also from coal and natural gas. Polyester fiber, commonly known as polyester, belongs to synthetic fiber in chemical fiber. In addition to polyester, its products also include acrylic fiber, nylon, fiber spandex and so on. From the manufacturing process and raw materials of polyester products, there are a lot of petroleum hydrocarbons, volatile organic compounds, smoke and dust, ammonia, hydrogen sulfide, HCL and so on. Waste polyester cloth will be produced during granulation.
If the exhaust gas purification facilities are not up to standard, the exhaust gas will exceed the standard. If there is no purification equipment, the pollution caused by direct exhaust gas will be more serious. In addition, granular cooling water also contains pollution factors such as oil and volatile phenol. In addition, there is the influence of equipment noise. However, all production activities of recycling and comprehensive utilization of petroleum products (such as plastics, asphalt, polyethylene, spandex, etc.). ) there will be relatively high pollution, and the environmental protection department will also strictly control the environmental impact assessment of such projects.
