Fluor provided detailed engineering for the polysilicon manufacturing process, technical support for procurement and field support. Having carried out previous polysilicon plant projects, Fluor has experts in offices around the world with project execution experience with similar technologies and technology providers. These experts, as well as site employees, supported Lanco in this venture.
A design conference held in the early stages of the project included technology providers, Fluor experts and Client personnel who put forward design solutions accepted by all key stakeholders. Fluor conducted safety studies with Lanco and contributed to a solution for chemical vapor deposition reactor cooling that realized a cost savings for the Client.
Fluor also helped to select vendors who knew the requirements of polysilicon facilities and were able to deliver in a timely manner. In addition, Fluor shared its experiences in Supplier Quality Surveillance, and a similar approach was used on the project. At the Client's request, Fluor shared its experience in construction management and quality assurance with Client personnel, adding to their understanding of the building requirements for this particular chemical facility.
The plant comprises a hydro chlorination plant, tri-chlorosilane vaporizer, chemical vapor deposition reactors, vent gas recovery, chunk and filament preparation and a host of infrastructure, offsite and utilities including steam boilers, electric substation and water and waste treatment facilities. Hydrochlorination process technology for converting manufacturing grade silica to solar or photo voltaic grade silicon was provided by GT Solar and Chemical Design Inc., both US companies.
