Distillation equipment and solvent recovery systems are used for steam and wastewater stripping, chemical product purification, and solvent recovery. Distillation equipment and solvent recovery systems consist of metal cylinders armed internally with perforated horizontal plates that are used to promote the separation of miscible liquids that ascend as vapor.
Distillation equipment and solvent recovery systems are used extensively in recycling applications and to reduce manufacturing waste. A solvent recovery system or solvent recover system usually comprises the use of a heating component and a condensation component to distill the liquid and separate the solvent from water. Solvent recovery equipment may also include a vacuum unit that enables the system to operate at temperatures that are typically lower than the solvent’s boiling point.
Distillation equipment and solvent recovery systems are used to perform steam stripping or distillation of wastewater for removal of hydrocarbons such as alcohols, ketones, and acetates. A distillation system can mix waste products so they are discharged as a sludge, paste, or powder depending on the specific industry’s best disposal practices. Distillation equipment and solvent recovery systems are used to recycle and recover contaminants from the manufacturing of polymers, resins, and paints.
Distillation equipment and solvent recovery systems may contain several other functional components, including an adsorption column or bed, where molecules of solvent in liquid or gas form adheres to the surface of a solid material, rather than enter the solid as in absorption. An aeration column is used when treating wastewater and involves pumping the water through a series of columns to add oxygen to the wastewater. Aeration increases the surface area of the contaminated water allowing a waste solvent recovery system to remove any volatile compounds more easily. A telescoping column may also be available from some suppliers of distillation equipment and solvent recovery systems.
