Solvent Recovery Systems For All Companies


Solvent recovery systems, also called solvent recyclers or solvent distillation systems, are dedicated to the process of recovering and cleaning solvent that’s already been used. They may be single machine units or a series of equipment. At their most basic, solvent recycling systems take used solvents that contain contaminants from paint, ink, dirt, and other suspended residue. The contaminated liquid is heated so that the solvent becomes vaporized while the contaminant particles are separated so they can be collected and properly disposed of. The solvent vapor is collected into a condenser, where it becomes liquid again. That liquid is then ready to renter the process to be used in the same manner as virgin solvent.
 


Industrial solvent recycling systems have become a common fixture for manufacturers, industrial painters, printers, and other service providers that use solvents like alcohol and acetone to clean their tools and equipment. The capability delivers many advantages.

The volume of hazardous waste that requires special handling, containment, and disposal is significantly reduced. Rather than disposing of dirty solvent, manufacturers can isolate the usable liquid and leave only the contaminants behind. This means that fewer resources, including labor, facility space, and disposal costs, need to be devoted to waste handling. 

It’s easier to remain in compliance with waste and environmental regulations when the hazardous material being transported out of a facility is reduced and also easier to handle. 

Overhead is reduced at the front end of the process by reclaiming solvent that can be used in place of virgin solvent. Depending on the capabilities and features of the individual solvent recycling system, it’s possible to automate the transfer of the recycled solvent into the start of the manufacturing or cleaning production line.

Modern solvent recovery equipment is very efficient and can recover up to 90 percent of the liquid solvent that enters the distillation process. Industrial solvent recycling systems also incorporate a lot of automated technology that can be incorporated into many different types of facilities and production lines.      

What is a solvent recovery system?

A solvent recovery system can include one or multiple pieces of equipment that are used to recycle and reclaim solvent. Dirty solvent enters the system and is heated until it vaporizes. The vapor is then condensed back into liquid form, leaving the contaminants behind. The recovered solvent can be reused in the same manner as virgin solvent. A solvent recovery system can provide a range of benefits to manufacturers and industrial painters, printers, cleaners, and other service providers that use acetone, alcohol, and similar chemicals in their production line.    

What is solvent distillation?

Solvent distillation is the process of heating a liquid solvent, such as acetone or alcohol, so that it vaporizes and is then condensed back into liquid form. The purpose of this process is to isolate usable solvent from contaminants like paint and ink particles and other residue suspended in the solvent. The now distilled and cleaned solvent can be collected for reuse. Any remaining waste can be collected and properly disposed of.     

What are the steps of solvent distillation?  

Solvent distillation involves several steps. First, the contaminated solvent enters the distillation unit and is heated until it evaporates. The suspended particles of any paint, ink, and other contaminants are left behind to be collected for disposal. The vaporized solvent is then moved into a condenser, where it returns to liquid form. The solvent is then cleaned and can be used in the same manner as virgin solvent. Depending on the specific solvent distillation unit, there may be additional processing steps, for example, some distillers will automatically move the cleaned solvent to the front end of the manufacturing or cleaning process.
