Abstract: A system of concentrating and separating waste solvent liquid includes a distillation tower, an extracting distillation unit, an extract agent recovery unit, and a vapor permeation film unit. The scheme of centrifugal distillation is specifically employed to collocate with vapor permeation to effectively concentrate the content of isopropanol in the waste solvent liquid to generate a final produce with ultra high concentration of isopropanol, and constantly recovers the extract agent. The system is able to be quickly settled to a steady state of operation with low power consumption because the extracting distillation unit has smaller size. Since no liquid is left in the extract agent recovery unit, operation risk is greatly reduced. In addition, the input feed is almost processed, overall efficiency is thus improved. The vapor permeation film unit further removes considerably little content of water from the organic solvent to increase the content of isopropanol up to 99.9% or more.

Abstract: A system and method for decontaminating a fluid and recovered vapor, particularly processing and recycling water used in an oil zone steam process, utilizing a vaporizer-desalination unit to separate a contaminated water flow into a contaminated disposal flow and a clean water vapor flow. The contaminated water flow is recovered after separation from a combined oil and water flow from an oil well. The clean water vapor flow is preferably passed through a steam generator to produce the steam used in the oil zone steam process. The steam is injected into the oil zone of a designated well and then extracted as the combined oil and water flow. Once primed with sufficient external water, the system and method is designed to operate continuously with minimal replenishment because of the water/vapor/steam cycle.

Abstract: A wastewater collection tank feeds a vaporizing unit through an inlet near the unit's top. A burner produces heat, which a blower blows through a blower tube that passes through the upper portion of the unit to the bottom portion of the unit. A substrate through which heated air can pass extends across the unit between the bottom of the blower tube and the wastewater inlet, and pall rings rest on the substrate. The heated air moving upward through the unit heats the pall rings and the falling wastewater, a substantial portion of which is vaporized at approximately atmospheric pressure. The vapor is vented from the top of the unit. Un-vaporized wastewater collects at the bottom of the unit and is recycled through the system with raw wastewater in the collection tank.
