摘要： The present invention provides a process for decreasing the relative humidity of a gaseous or vaporous process stream, while increasing the temperature thereof. A preferred embodiment of the process of the present invention is implemented using a bleed valve, a positive displacement blower located downstream therefrom, and a control mechanism for opening and closing the bleed valve. When opened, the bleed valve preferably permits ambient air to admix with the gaseous process feed stream to form the blower feed stream. Increased blower gas throughput results in a lower magnitude gas temperature increase across the blower. The control mechanism used in the practice of the present invention involves monitoring the temperature of the blower effluent (or the gaseous feed to a downstream unit operation), and controlling operation of the bleed valve in accordance with that temperature reading.

摘要： Methods and systems for recovering groundwater, gases and vapors from subsurface locations in a single, integrated operation by applying a vacuum to groundwater recovery wells are disclosed. Selective recovery of specific contaminants from zones of interest containing high levels of those contaminants is achieved by manipulating the local water table level. Groundwater recovery systems may also utilize eductor systems having venturi nozzles that create a vacuum networked. A plurality of such recovery wells operated using eductor systems may be operated by a single pump at or above grade level. In this fashion, a network of recovery wells may be operated using a single pump and control system. The recovery methods and systems of the present invention are preferably utilized in association with known contaminant removal systems to provide complete removal of contaminants and improved remediation efficiencies.
