20130193072 | WATER SEPARATION METHOD AND APPARATUS - A system for treating fractionated water from an oil and gas well. The system comprising a filter system, a diffusive membrane system, a plurality of membrane sensors, and at least one membrane controller. The filter system is fluidly connected to the diffusive membrane system, wherein the filter system comprises a plurality of straining filter banks. The diffusive membrane system comprises a plurality of membrane banks each having an inlet and an outlet. The plurality of membrane sensors are positioned at the outlet of each of the plurality of membrane banks, and the plurality of membrane sensors are configured to detect the total dissolved solids level at the outlet of each of the plurality of membrane banks. The at least one membrane controller is programmed to selectively disengage and isolate at least one of the plurality of membrane banks from fluid communication with the system upon detection if the total dissolved solids level at the outlet of one or more of the membrane banks is above about 20,000 ppm. A method is also provided. | 08-01-2013 |
20110139603 | SYSTEMS AND METHOD FOR LOW TEMPERATURE RECOVERY OF FRACTIONATED WATER - In accordance with one embodiment, a method for treating fractionated water produced by a hydraulic fracturing process is provided. The method includes decanting a fractionated water stream in at least one decanter. The decanter is maintained at a temperature ranging from about 90° F. to about 120° F. The method also includes flashing the decanted water in at least one first flash tank and at least one second flash tank in fluid communication with one another to provide a residual concentrate stream. The first flash tank is operated at a temperature ranging from about 180° F. to about 200° F. and the second flash tank is operated at a temperature ranging from about 140° F. to about 160° F. Both the first flash tank and the second flash tank are maintained at a vacuum pressure. The method also includes evaporating the residual concentrate stream in at least one evaporator kettle to produce a concentrated brine. The evaporator kettle is fluidly connected to the second flash tank, and the evaporator kettle is operated at a temperature ranging from about 95° F. to about 115° F. The evaporator kettle is maintained at a vacuum pressure. The method also includes dewatering the concentrated brine to produce recovered salt having less than about 20 wt. % water. | 06-16-2011 |
