摘要： The invention relates to a system and method of treating a flow back fluid exiting a well site following stimulation of a subterranean formation. The invention utilizes a two-stage membrane process during the period that the gas contains high concentrations of CO2 by volume, and allows for separation of CO2 from the natural gas components, providing pipeline-quality natural gas (approximately 5% CO2 by volume) to the gas collection system.

摘要： A method and apparatus for injecting a gas into a liquid in which a rotating helical impeller within a draft tube submerged in the liquid creates a liquid flow within the draft tube. Gas bubbles are injected into the draft tube either above or below or alongside the helical impeller or in all three locations. The liquid is drawn into the draft tube with a superficial velocity greater than a substantially uniform terminal ascent velocity of the gas bubbles to allow entrainment of undissolved gas bubbles in the bulk liquid into the liquid being drawn into the draft tube. The gas bubbles are injected with a uniform diameter of between about 10.0 microns and about 1.0 millimeters. The small bubble size enhances the dissolution of the gas into the liquid and also allow the entrainment of the gas into the liquid being drawn into the draft tube.

摘要： A system and method for oxygenating an aerobic sludge digester is provided. The disclosed embodiments include an aerobic sludge digester tank or vessel having a mechanically agitated contactor disposed therein, an oxygen injection subsystem adapted to inject oxygen into the digester tank proximate the mechanically agitated contactor. The embodiments of the mechanically agitated contactor include an agitator or impeller disposed within the draft tube which makes the draft tube the primary site for the gas-liquid mixing. In particular, the agitator or impeller is adapted to create gas bubbles having an average diameter between about 0.3 mm and 3.0 mm which are then dispersed into the aerobic digester. The mass transfer efficiency associated with the present system and method is enhanced from the combined effect of oxygen dissolution into the sludge and greater bubble residence time.

摘要： A system and method for the treatment and reduction of sludge via ozonation in a wastewater treatment process is disclosed. The sludge treatment system comprises: a sludge ozonation reactor coupled to an activated sludge treatment basin and adapted to receive a liquid stream of sludge containing biosolids from the activated sludge treatment basin. The sludge treatment system also includes an ozone-enriched gas injection system operatively coupled to the reactor and adapted to inject ozone-enriched gas into the liquid stream at or upstream of the sludge ozonation reactor. The sludge ozonation reactor is configured to allow effective gas-liquid contacting between the ozone-enriched gas and the liquid stream so as to oxidize the biosolids in the liquid stream and initiate bacterial cell lysis thereby reducing the biosolids. Upon reduction of the biosolids, the liquid stream is returned via a return line to the activated sludge basin or other discharge point.

摘要： A method of controlling an oxygen-free heat treating process in an atmospheric pressure furnace is disclosed. The present method employs an oxygen-free gas atmosphere including hydrogen gas in concentrations between about 1.0 percent to 10.0 percent, a hydrocarbon gas, such as propylene, in concentrations of between about 0.1 percent and 10.0 percent that varies as a function of time, with the balance of the gas atmosphere being nitrogen. The presently disclosed oxygen-free carburization process uses a precisely controlled gas atmosphere to minimize inter-granular oxidation, eliminate the formation of soot and cementite, and avoid hydrogen embrittlement.
