Possibly the largest ever dichlorosilane (DCS) redistribution process (RDR) project has been successfully completed by Dynamic Engineering (DEI) for GCL Solar’s polysilicon plant. The RDR project for GCL was designed to process 10,000 mta of DCS, which eliminates the byproduct through conversion of DCS to trichlorosilane (TCS). GCL Solar is planning to expand polysilicon production to 18,000 MTA by end of 2009 and 21,000 MTA by end of 2010.

“Operating a polysilicon plant optimally is critical, which is why we chose to work with DEI to help us recover byproducts effectively,” commented Gong Shan Zhu, chairman, executive director, and CEO of GCL-Poly. “GCL Solar is committed to developing best-in-class technologies for the manufacturing of polysilicon which in turn can guarantee production efficiency and reliable product quality.”

Kevin Drumm, DEI's VP of business development said that his company “has a 20-year history of bringing the most effective processes to leading pharmaceutical and high-purity chemical companies like GCL Solar, while minimizing capital investment required with more extensive revamps. DEI’s DCS redistribution process proves you can reach optimal production and reduce waste without high investment costs.” 

TCS is the silicon gas used in the production of polysilicon in a chemical vapor decomposition reactor, while DCS is a waste byproduct that occurs during this process.
