Abstract: A method of mixing an oxygen gas with a hydrocarbon-containing gas includes the steps of wet scrubbing the oxygen gas in a wet scrubber, supplying oxygen gas from the wet scrubber to a gas mixer and mixing the oxygen gas with the hydrocarbon-containing gas in the gas mixer. Wet scrubbers for use in the method may take various forms, including packed-tower, bubble cap, and sparger-type wet scrubbers. The removal of the particulate matter reduces the risk of ignition of the hydrocarbon-containing gas in the gas mixer. The use of a wet scrubber in the oxygen supply line overcomes many problems currently faced with screen and filters, as per current practice.

Abstract: An air filtration system is described for removing oil and grease entrained in air extracted from the region above a cooker. The system comprises a first mesh screen filter leading to a first chamber, in which two nozzles 10 create two separate continuous water curtains 15a, 15b which overlap when viewed in the direction of the air flow to form a combined curtain extending across the region through which the air passes.

The water curtains 15a, 15b, 15c, 15d cool and condense vaporized oil and grease within the air, which condensed oil and grease droplets fall with the water into a container. The main bore of each nozzle is of circular cross-section, but a profiled plate causes the resulting water curtain to have a width which is narrow relative to the diameter of the nozzle bore.

Abstract: A method, apparatus and system for minimizing a quantity of particulate matter entrained within a gas stream is provided. A coarse filter removes at least a portion of particulate matter having a relatively-large particle size from the gas stream. An agglomerator agglomerates particulate matter having a relatively-small particle size remaining in the gas stream into particulate clusters after the portion of the particulate matter having the relatively-large particle size has been removed by the coarse filter. An injector introduces an agglomerating material into the gas stream before the gas stream enters the agglomerator. The agglomerating material promotes agglomeration of the particulate matter having the relatively-small particle size into the particulate clusters. And a second filter receives the gas stream and removes at least a portion of the particulate clusters entrained within the gas stream exiting the agglomerator.

Abstract: An air scrubber for removing oils and contaminates from air has an underside inlet for the introduction of contaminated air. The contaminated air passes through a reduced aperture passageway which prevents retrograde flow of contaminates or cleaning fluids contained in the scrubber. The contaminated air is thereafter directed upwards through a scrub reservoir having a plurality of apertures, such that the contaminated air passing through the apertures forms jets which cause interaction between the cleaning fluid and the contaminates, thereby creating droplets containing cleaning fluid with entrapped contaminates, and cleaned air. The droplets and air are directed to a mist eliminator having a plurality of chevron V structures which capture the droplets and return them to the main reservoir. A circulating pump moves cleaning fluid from the main reservoir to an upper reservoir which spills into the cleaning reservoir.

Abstract: The present invention describes methods and systems for extracting, capturing, reducing, storing, sequestering, or disposing of carbon dioxide (CO2), particularly from the air. The CO2 extraction methods and systems involve the use of chemical processes. Methods are also described for extracting and/or capturing CO2 via exposing air containing carbon dioxide to a solution comprising a base—resulting in a basic solution which absorbs carbon dioxide and produces a carbonate solution. The solution is causticized and the temperature is increased to release carbon dioxide, followed by hydration of solid components to regenerate the base.

Abstract: With a conventional method of causing impregnation of a liquid seasoning into food, it takes many hours for the liquid seasoning to substantially make permeation. Occasionally, impregnation was not at all attained. Such proposals have been made that food soaked in a liquid seasoning is pressurized, or that water content of food is dehydrated. An apparatus and a facility for carrying out processing to food need to be larger in size, thereby taking cost and being not suitable for mass production. Also, uniform permeation of the liquid seasoning in a short time was not achieved. The present invention provides a liquid seasoning used for seasoning food subjected to processing with a micro-nano bubble generating device, thereby enabling the liquid seasoning to have impregnation to food in a short time, particularly, facilitating impregnation of good flavor and taste compositions other than salt.

Abstract: The present invention consists of a system related to vacuum cleaners, more specifically, to a system designed to filter the micro-dust that escapes from the bag with the air. The inlet turbine will suck the dirt into the vacuum cleaner bag Zone 1 where the air will escape into Zone 2. At the same time, the micro-dust will also escape with the air into Zone 2. The exhaust turbine sucks the dust content air in Zone 2; hence, the dust content air will travel through the dust collector pipes then through the dust collector main pipe, then through the small “L” type pipes, then hit the water dumping the dust into the water in the compartment one. The dust content air then travels up to get into the small “L” type pipes in the compartment two, then hits the water.
