Koch Modular Process Systems designed and constructed this product purification and solvent recovery system. This five-column modular distillation system was designed to recover aliphatic and aromatic solvents, a chlorinated product and high-boiling oil from various feed streams.
A solvent recovery system such as this one allow for the recovery of solvents from waste streams. These solvents are then recycled, providing cost-saving benefits, saving of natural resources, and compliance with government guidelines for waste reduction.
Recovery efficiencies are typically around 80%, but higher efficiencies are possible. Costs are reduced dramatically due to the reduction of waste, which would otherwise be dealt with through off-site solvent recovery or disposal.
