Solvents There are 3 types of solvents: oxygenated, hydrocarbon, and halogenated.
Oxygenated solvents include such products as ketones, glycol ethers, and alcohols.
Hydrocarbon solvents tend to be distilled to suit an intended purpose. This means the composition of the solute, color, and smell of the final product will vary greatly, depending on the purpose for the final product.
Halogenated solvents are actually hydrocarbon solvents that have undergone a chlorinating process.
Solvent
Recovery SC For waste solvent with less than 20% solids content, the PRI SC units are available with capacities from 10 to 220 gallons. These are safe and easy to use units for either batch or continuous operation.
Generating greater than a drum per week of waste solvent can make a solvent distillation unit a viable alternative to off-site disposal or recovery.
Safety features include intrinsically safe sensors, explosion proof electronics, and compliance with NFPA and NEC codes.
Solvent
Recovery for High Solids Content SCR For dirty solvent with high solids content,an exclusive rotating scraper blade assembly is incorporated to assure optimum efficiency and consistent clean solvent production throughout the recycling process.
All systems are available with a wide range of options to suit specific application needs. Vacuum or atmospheric distillation systems, solvent storage tanks, pumps, automated control systems and Nitrocellulose safety packages are just a few examples.
With operating capacities to 800 gallons and recovery rates up to 140 GPH, these models are designed for broad applications across a variety of markets, including aerospace, paint and coatings, printing, converting, manufacturing and automotive.
These solvent recovery units are elevated, with a cone shaped bottom facilitating sludge discharge into a 55 gallon drum for easy disposal. All models are constructed for Class I, Division 1, Group D environments using a combination of intrinsically safe sensors and explosion-proof electrical components. Units are available with an electrically heated oil jacket or an ASME steam-heated jacket. Each system is manufactured to comply with NFPA and NEC codes applicable to the vessel and installation. A Programmable Logic Controller (PLC) monitors the unit’s operation, and an exclusive Process Performance Control (PPC) software package provides maximum throughput and solvent recovery while minimizing wastes requiring disposal.
Solvent
Recovery for Large Applications LSRThe Series LSR solvent distillation units, the heavy-duty work horse of the PRI line, is built to handle difficult and large scale waste streams. An ASME Code, stainless steel vessel houses the patented rotating scraper assembly that continually scrapes the sidewalls to assure optimum heat transfer efficiency and optimum output rate.
The LSR solvent recycling units achieve maximum efficiency with a Programmable Logic Controller (PLC) and PRI's exclusive Process Performance Control (PPC) software is built to process a continuous feed of high particle laden solvent with solids content up to 35%. With recovery rates up to 500 GPH, it is designed for high volume applications such as paint and coatings manufacturers.
Parts
Washing Systems PRI parts washing systems are large, industrial duty, enclosed chamber wash systems designed for washing flexographic and gravure press parts and a variety of other applications.
These systems minimize make-ready time and reduce employee exposure to cleaning chemicals. They also reduce chemistry costs, reduce manpower requirements and reduce environmental emissions.
All parts washing systems are "end load" designs in which parts are loaded onto mobile carts and pushed into the unit for a four step cleaning process. Full automation allows operating personnel to perform other duties while the system is in operation.
Solvent based systems can include integral solvent recovery systems allowing
continuous reuse of the solvent wash solution. An integral VOC reduction system
captures solvent fumes for reuse minimizing fugitive emissions.
Non-flammable cleaning solvents can be used that have low emmissions and will clean solvent and water based inks, adhesives and top coats.
For removal of water based chemistries, consider the PRI washer models that use water and detergents as the cleaning solution.

The Texas Commission on Environmental Quality (TCEQ) has approximately 3,000 employees, 16 regional offices, and a $463.9 million budget.
The Environmental Protection Agency (EPA) employs 18,000 people across the US, with HQ in DC, 10 regional offices, and more than a dozen labs. The EPA Administrator is appointed by the President of the US and has a budget of $7.6 billion.
