The static diffuser includes a flow-straightening structure configured to reduce vortex flows in fluid flows passing through the exhaust outlet.

Abstract: A contact tray is provided with a tray deck and dividing walls which form groupings of one or more cans and one or more downcomer inlets distributed across the tray deck. The cans have walls that surround vapor openings in the tray deck that permit upward passage of a vapor stream into the cans. Downcomers extend downwardly from the downcomer inlet and are positioned for delivering a liquid stream into the center of cans positioned on a tray deck of an underlying contact tray. Discharge openings are provided in the walls of the cans to allow the liquid stream to exit the cans. The dividing walls direct the exiting liquid stream into the downcomer inlets in the same grouping and prevent or impede the liquid stream from flowing to a low side of the tray deck.

Abstract: The invention is a high capacity and high efficiency co-current vapor-liquid contacting apparatus for use in distillation columns and other vapor-liquid contacting processes. The apparatus is characterized by an arrangement of modules in horizontal stages rather than tray-like construction. The modules define a co-current contacting volume and in an exemplary configuration the modules include a liquid distributor, a demister, a receiving pan and a duct. The modules of one stage are rotated to be non-parallel with respect to the modules of an inferior stage, a superior stage, or both. Variations relate to the design of the individual elements such as the demister, liquid distributor, ducts, and contacting volumes, and the overall arrangement of the apparatus.

Abstract: The present invention discloses a system for flue gas treatment, wherein the provided system comprises a quench module, a first control module, a filter collecting module, a wet scribing module and a regeneration module. In this system, parts of the particles contained in flue gas are removed in the quench module and the wet scribing module by a first scrubbing solution, and then in wet scribing module a second scrubbing liquid containing particles is formed. Next, the second scrubbing solution is treated in the regeneration module to form a third scrubbing solution, wherein the third scrubbing solution is then fed back to the quench module and/or the wet scrubbing module to substitute the first scrubbing solution for repeating what originally performed via the first scrubbing solution. Furthermore, this invention discloses a method for flue gas treatment.

Abstract: This invention provides an improved method and apparatus for collecting a liquid overspray from a gaseous mist and separating the liquid from the gas stream. The invention has utility in a wide variety of chemical application processes such as to reduce the hazards and waste characterized by prior art methods and provide a mechanism for the in-line recycling of the overspray liquid. In a preferred embodiment, the present invention comprises a hooded recovery unit which is oriented above and about a conveyor system in which a workpiece travels through a spray zone in which a chemical or other liquid is applied to the workpiece. In such a situation, the present invention provides for the recovery of overspray liquid which would otherwise be wasted as the liquid or chemical is applied to the workpiece during the period in which the workpiece passes through the recovery unit. The system includes a spray application chamber, a conditioning chamber, and an overspray collection chamber.

Abstract: This concept concerns a vapor/liquid contacting tray which is useful in distillation and related mass transfer or heat transfer applications where liquid flows down and gas or vapor flows up through a vessel. In this device, the perforated area is relatively small, so the liquid is entrained upward. The liquid flow is then directed downward into a large disengaging area. The downward momentum of the liquid and the large disengaging allow for high liquid and vapor rates without overloading the vapor/liquid disengaging capacity of the device.

Abstract: An air washer includes an upwardly-open vessel for holding an air washing liquid. An air inlet opening into the upwardly open vessel introduces air to be washed below the upper level of the air washing liquid, and a chamber above the upper level of air washing liquid has inner and outer walls. A fan spaced from the upper level of air washing liquid is positioned within the outer wall of the chamber. The fan pulls an air flow through the inner wall of the chamber and exhausts it to an exhaust path downstream of the fan. Operation of the fan induces air to pass through the inlet and to be washed by the air washing liquid in the vessel and to pass through the chamber to the fan and then to be exhausted through the exhaust path. Air washing liquid entrained as liquid droplets in the cleaned air is propelled outwardly by the fan and centrifugally removed from the cleaned air.

Abstract: A system is provided for recovering volatile-liquid vapor from an air-volatile liquid vapor mixture. The system includes a reaction vessel having a bed of adsorbent for adsorbing volatile liquid vapor and producing relatively volatile liquid vapor-free air. The system further includes a liquid seal vacuum pump for regenerating the adsorbent, a first conduit for circulating the air-volatile liquid vapor mixture through the system and a second conduit for circulating seal liquid to the vacuum pump. A cyclonic separator separates the seal liquid from the air-volatile liquid vapor mixture produced during bed regeneration. A mechanism is also provided for removing the volatile liquid vapor from the air-volatile liquid vapor mixture separated from the seal liquid. A method of recovering volatile liquid vapor from an air-volatile liquid vapor mixture is also disclosed.

Abstract: A method of separating a mixture of gases by the following stages:a) absorbing a part G2 of a gas mixture G1 by a solvent L1 in an absorption zone C1;b) expanding the solvent L1, leading to partial vaporization of the absorbed gases G2 and cooling of the solvent L1;c) desorbing the gas fraction G2 in a desorption apparatus D1 having a reboiling zone B1 and an internal heat exchange zone Z1, wherein the solvent L1 from stage (b) is circulated in countercurrent contact with the vapor phase, and simultaneously has counter-current heat exchange with the solvent phase from the reboiling zone B1;d) passing the regenerated solvent leaving the reboiling zone B1 into the heat exchange zone Z1, and transferring the regenerated solvent to the top of said internal heat exchange zone; ande) recycling the regenerated solvent to the absorption zone C1.

Abstract: An air pollution control system incorporating a venturi scrubber and a method of cleansing a particulate-laden, contaminated gas flow are disclosed. Spray nozzles are used to introduce optimized droplets of a scrubbing liquid into the venturi to maximize particle collection efficiency. Due to the very small size of the spray droplets they absorb gases in quantities in excess of the amount predicted by Henry's law. After passing through the venturi the spray droplets are reconsolidated and flow to an enclosed container. Due to the applicability of Henry's law to the relatively large reconsolidated volume of scrubbing liquid, the liquid is naturally effervescent. Bubbles formed in the liquid volume cause suspended particles in the liquid to rise to the surface where they form an easily collected surface scum. The effervescent gases, at least some of which may be noxious, are then incinerated or otherwise treated.

Abstract: An improved apparatus and method for spraying a liquid into a flue gas provides a boundary layer of gas along a perimeter of a dry scrubber housing to prevent deposition of wet material on the sidewalls thereof. The boundary layer of gas includes the use of heated air, particulate free flue gas, and/or dust laden flue gas. The system is operated at/or near the saturation temperature to further increase removal efficiencies and reagent utilization.
