Mobile Self-Contained System For On-Site Recovery Of Solvents
US Patent:
5102503, Apr 7, 1992
Filed:
Aug 4, 1989
Appl. No.:
7/389577
Inventors:
Thomas J. Silinski - Lake Orion MI
Robert A. Walz - Utica MI
Robert A. Walz - Utica MI
Assignee:
Environmental Technology Group Corporation - Rochester Hills MI
International Classification:
B01D 122, B01D 302, B60P 322
US Classification:
202 83
Abstract:
A system for on-site recovery of reusable industrial waste components, such as solvents, from a liquid waste stream includes a trailer that is internally partitioned to separate system components through which the waste stream passes in a first partitioned section of the trailer from support and control components in the second trailer section. Input waste is fed into a horizontal thin-film evaporator within the first trailer section, while steam is fed in a closed loop through the evaporator from the second section of the trailer for evaporating volatile solvents in the waste stream, and thereby separating the volatile solvents from non-volatile liquid and solid components of the waste stream. The evaporated volatile solvents are fed to a heat exchanger, again enclosed within the first partitioned section of the trailer, for recondensation through heat exchange with a coolant fed to the heat exchanger in a closed loop from the second trailer section. The recondensed solvents are then fed to a water separator tank and a molecular sieve for separation of immiscible and miscible water from the solvents, and thence to a holding tank for resupply to the customer.

US Classification:
052/200000, 052/223700, 052/469000
Abstract:
A roof panel () for a sun room has a polystyrene foam core () and two aluminum covers () and () adhered to the top () and bottom () of the foam core. At least one groove () is cut into the foam core and a rib () is laterally fitted into the groove. The rib has its minor axis vertically oriented and its major axis running longitudinally with or parallel to the longitudinal axis of the panel to provide significant increase in strength to the panel.
