A quench system for cooling hot flue gases from combustion systems is disclosed. The quench system includes a venturi mounted in a quench vessel. The water level in the quench vessel may be raised or lowered in accordance with the flow rate of the gases to be quenched. When the pressure drop across the venturi is insufficient to achieve the desired cooling to adiabatic saturation temperature, the water level is increased so that the downcomer connected to the venturi is submerged and the additional pressure drop further cools the flue gases.

Method and apparatus for quenching hot flue gases

An improved process for eliminating the liquid blowdown stream from the wet flue gas scrubbing equipment of an incinerator system. The liquid blowdown stream from the main wet scrubbing system is mixed with a hot flue gas slipstream. The water is evaporated and the residual solids are removed, thereby producing a dry waste stream for disposal and a solids-free flue gas slipstream for exhaust.

Liquid blowdown elimination system

A system for removing brine from oil well production (12) in which fresh water (50) or less saline water (50) is passed in counterflow to the oil well production (12) through electric fields established between a plurality of composite electrodes (26). The electrodes (26) are of a laminar construction having a centrally located conductive member (30) surrounded by an electrically nonconductive region (28). With a nonmodulated voltage supply (144) connected to conductive member (30) a plurality of electric fields, some having uniform gradient and others having nonuniform gradient, are established between adjacent composite electrodes (26) in the direction of flow of both the oil well production (12) and the dilution water (50). Composite grids (26) have an inherent current regulating characteristic that reduces the tendency for arcing and suppresses sustained arcing should an arc occur.

Distributed charge composition electrodes and desalting system

Electrodes, in the form of plates, are held parallel to each other to form passageways in which electrostatic fields are generated when the plates are charged by a source of variable voltage. The variable voltage is programmed to establish an initial electrostatic field strong enough to mix polar and nonpolar fluids. The mixture is then flowed through the electrostatic field which is of the strength needed to coalesce the polar fluids which have united with a contaminant in the nonpolar fluid.
