Scope

Main technical content: This document specifies the low-carbon and clean silane fluidized bed process for the production of high-purity polysilicon, and compares it with the modified Siemens process; sets energy consumption limits for each unit of polysilicon production; defines low-carbon indicators for the production of high-purity polysilicon; and outlines requirements for testing and process control, major equipment, main raw materials, labor safety and occupational health, operation and maintenance, etc. This document is applicable to the production audits, production performance evaluations, and production performance announcement systems of polysilicon enterprises in China. It can also be used as a reference for environmental impact assessments, environmental inspections, and industry access evaluations of other new or expanded projects.
