1. Dow Corning Corporation

Under this project, Dow Corning has studied direct process residue (DPR) hydrogenolysis since 1994. Currently, a commercial scale plant is operating at Dow Corning's Carrollton, Kentucky, facility. A full scale plant has been designed and is presently being constructed at Dow Corning's Barry, Wales (UK), plant. The Barry Plant is scheduled to start up the first half of 2001. The process reacts filtered DPR with chlorosilane monomers at high temperature and pressure. The Carrollton process routinely demonstrates DPR conversions from 59% to 89% on a monthly basis. The reaction product contains high concentrations of valuable monomers such as dimethyldichlorosilane and methyldichlorosilane. By converting waste DPR to valuable products, the technology significantly reduces the waste from the basic silicones manufacturing process.
