Mobile self-contained system for on-site recovery of solvents

A mobile system for on-site recovery of reusable components from a liquid waste stream comprising:

• a wheeled support base including means for transport of said base between job sites,
• evaporator means carried by said base and including inlet means for selectively receiving a waste stream at a job site and directing such waste stream in a continuous flow into said evaporator means, means for heating the waste stream during flow through said evaporator means to a temperature coordinated with residence time of the waste stream in said evaporator means for evaporation of volatile from non-volatile components of the waste stream, and first and second outlet means on said evaporator means for receiving said volatile and non-volatile components respectively,
• said means for heating said waste stream in said evaporator means comprising a steam generator separate from said evaporator means for generating steam at a controllable temperature, means for circulating steam from said generator in a closed loop through said evaporator means, and means for controlling the temperature of steam in said closed loop,
• condenser means coupled to said first outlet for receiving and condensing said volatile components to provide a condensed component stream that includes water and non-aqueous product components, said condenser means comprising a heat exchanger operatively connected to said first outlet of said evaporator means, and means separate from said heat exchanger for circulating coolant through said heat exchanger in heat-exchange relationship with said volatile components,
• means coupled to said condenser means for separating water from product components in said condensed component stream, and
• means coupled to said second outlet of said evaporator means and to said water-separating means for separately delivering said non-volatile components and said product components at the job site,
• said wheeled support base comprising a closed partitioned enclosure having said evaporator means, said heat exchanger, said water separating means and said delivery means disposed in a first partitioned chamber, and said steam generator and said coolant circulating means disposed in a second partitioned chamber separate from said first chamber.
