Polycrystalline Silicon Project


This Solar-grade Polysilicon plant is located at Xinjiang, China. The design capacity is 50,000 t/a based on the annual operating time of 8,000 hours. The plant consists following main process units: Synthesis of Hydrogen Chloride, Cold hydrogenation, Distillation, Reduction, Reforming, Exhaust gas recovery, Process waste gas treatment, Hydrogen production, Synthesis of Trichlorosilane, Tank farm and Utilities.

Encryo provide the detail design and construction supervision service for this project, and finished the 3D model design for 1,200 equipment, 200,000 meters pipes and 10,000 instruments and control valves.
