Solvent Recovery and Environmental Application of Modular Processing

Koch Modular Process Systems, LLC. specializes in the design and construction of complete modular process systems including solvent recovery applications.

Solvent recovery or solvent reclamation is often a critical economic factor in determining the feasibility of a new project or plant expansion. Environmental regulations, new solvent costs and waste disposal costs can easily exceed the cost of solvent recovery equipment and operation. Koch Modular has experience with many recovery techniques for a wide range of solvents. See below for a detailed and expanding list of our solvent recovery experience. Our engineers excel at solving difficult new solvent recovery applications, including purification of solvents to virgin quality or better.

Koch Modular also provides process studies, laboratory and pilot testing, VLE development and complete process design engineering packages.

Typical Solvent Recovery System

This modular system is designed to operate in a semi-continuous mode to recover isopropyl alcohol (IPA), near it’s azeotropic concentration,from an aqueous process stream generated in the production of a pharmaceutical. The system is subsequently operated in a continuous mode to dry the IPA, using azeotropic distillation with isopropyl ether as the entrainer.
