    • An air stripper in the form of an submerged gas evaporator or a submerged gas reactor that includes a vessel, a gas delivery tube partially disposed within the vessel to deliver a gas into the vessel and a contaminated liquid inlet that provides a contaminated liquid to the vessel at a rate sufficient to maintain a controlled constant level of process fluid within the vessel. A weir is disposed within the vessel adjacent the gas delivery tube to form a first fluid circulation path between a first weir end and a wall of the vessel and a second fluid circulation path between a second weir end and an upper end of the vessel. During operation, gas introduced through the tube mixes with the process fluid and the combined gas and fluid flow at a high rate with a high degree of turbulence along the first and second circulation paths defined around the weir, thereby promoting vigorous mixing and intimate contact between the gas and the process fluid. This turbulent flow develops a significant amount of interfacial surface area between the gas and the process fluid resulting in a reduction of the required residence time of the gas within the process fluid to achieve thermal equilibrium and/or to drive chemical reactions to completion, all of which leads to a more efficient and complete evaporation, chemical reaction, or combined evaporation and chemical reaction process.
    • 浸没式气体蒸发器或潜入式气体反应器形式的空气汽提器,其包括容器,部分地设置在容器内以将气体输送到容器中的气体输送管以及向容器提供污染液体的污染液体入口 以足以在容器内保持受控恒定水平的工艺流体的速率。 堰被设置在邻近气体输送管的容器内,以在第一堰端和容器的壁之间形成第一流体循环路径,以及在第二堰端和容器的上端之间的第二流体循环路径。 在操作过程中,通过管道引入的气体沿着沿堰周围限定的第一和第二循环路径以高速率高速湍流混合过程流体和组合的气体和流体流,从而促进了湍流之间的剧烈混合和紧密接触 气体和过程流体。 这种湍流在气体和过程流体之间产生显着量的界面表面积,导致气体在工艺流体中所需的停留时间减少,以实现热平衡和/或驱使化学反应完成, 这导致更有效和完全的蒸发,化学反应或组合的蒸发和化学反应过程。

    • Apparatus and method for producing at high efficiency vaporization a precisely controllable, continuously adjustable gas-phase flow of a vaporizable liquid (e.g., hydrogen peroxide) in a carrier gas (e.g., air) are disclosed. The gas-phase product flow can be substantially continuous, low-temperature, unsaturated with respect to the vaporized vaporizable liquid, and of substantially constant vaporized vaporizable liquid concentration as a function of time. Fine particles of the vaporizable liquid are produced and introduced into the flow of carrier gas/vapor in a vaporization plenum with a sufficient flow of carrier gas/vapor to provide a curtain of carrier gas/vapor between substantially all of the fine particles of vaporizable liquid and the inner surface of the vaporization plenum.

    • Small quantities of one or more liquids having a high boiling point dispersed with a large quantity of one or more immiscible liquids having a lower boiling point are separated in a rapid and efficient manner. A non-reactive compressed gas is heated by recycled energy and make-up energy to a temperature above the boiling point of at least one liquid but below that of at least one other liquid. The heated gas is combined with the unheated liquid mixture to be separated, and the liquid-gas blend is mixed, heated and distributed by an improved nebulizer, forming a mist inside a vessel containing a pool liquid of at least one liquid having a boiling point higher than that of at least one other liquid, which pool liquid has been heated to a temperature above the boiling point of at least one liquid but below its own boiling point. The liquid having high-boiling-point in the mist settles by gravity and merges with the pool liquid. The vapor of liquid having low-boiling-point in the mist is discharged as the gaseous effluent which can be wasted or recovered. The resulting fractions of each component are then collected separately.
