Disclosed are an activated carbon adsorption tower and a gas purification device. An activated carbon adsorption tower comprises an adsorption tower body (1), a gas inlet (2) and a gas outlet (3) arranged on the adsorption tower body (1); the adsorption tower body (1) is provided with an activated carbon passage (11), a swash plate (12) and a gas passage in communication with the gas inlet (2) and the gas outlet (3); the gas passage is separated by the swash plate (12) into a U shape or serpentine shape, making the gas passage pass through the same activated carbon passage (11) from the opposite direction at least once; and the activated carbon passage (11) is provided with flowing activated carbon inside and gas holes on the passage wall for communicating with the gas passages on both sides.

A scrubbing assembly for treating malodorous air by chemical scrubbing one or more chemical components from an influent airflow, particularly one or more chemical components that have become airborne from chemical intervention solutions used during food processing, such as vapors from peroxycarboxylic acid solutions used during food processing. The peroxycarboxylic acid vapors are removed from air in a continuous manner within the scrubber assembly utilizing a neutralizing chemical solution to provide a treated effluent airflow that can be returned back to the point of use area from which the malodorous air was removed for treatment.

Electronic device processing assemblies including an equipment front end module (EFEM) with at least one side storage pod attached thereto are described. The side storage pod has a side storage container. In some embodiments, an exhaust conduit extends between the chamber and a pod plenum that can contain a chemical filter proximate thereto. A supplemental fan may draw purge gas from the pod plenum through the chemical filter and route the gas through a return duct to an upper plenum of the EFEM. Methods and side storage pods in accordance with these and other embodiments are also disclosed.

A wet scrubber at least comprises a treatment tank, a jet pipe, a gas-liquid separation component, and a spray component. The treatment tank is used to contain a cleaning solution. The jet pipe is disposed in the treatment tank, by injecting the cleaning solution to suck in an exhaust gas, and mixing the cleaning solution with the exhaust gas, and directly injecting into the cleaning solution contained in the treatment tank, thereby forming a plurality of microbubbles in the cleaning solution to dissolve the exhaust gas and capture solid particles in the exhaust gas. The gas-liquid separation component is used to filter and block water mist raised in the cleaning solution. The spray component is used to prevent the solid particles from clogging the gas-liquid separation component.

The present disclose is directed to a method for controlling iodine levels in wet scrubbers, and, in particular, recirculating wet scrubbers by removing the iodine from the scrubbing solution, such as by using ion exchange, absorption, adsorption, precipitation, filtration, solvent extraction, ion pair extraction, and an aqueous two-phase extraction.

A fossil fuel fired power plant exhaust gas clean-up system is provided to remove detrimental compounds/elements from the exhaust gas emitting from the power plant to protect the environment. This is accomplished primarily by directing the exhaust gas from a fossil fuel fired power plant through both a reaction chamber containing a chemically produced compound and a catalytic converter. The final exhaust gas can now be safely exhausted to the atmosphere and only contains nitrogen gas, oxygen, water and a trace amount of carbon dioxide.

In one embodiment, a separation membrane includes: a porous support structure, wherein the porous support structure comprises a system of continuous pores connecting an inlet of the separation membrane to an outlet of the separation membrane; and at least one alkali metal hydroxide disposed within pores of the porous support structure. Other aspects and embodiments of the disclosed inventive concepts will become apparent from the detailed description, which, when taken in conjunction with the drawings, illustrate by way of example the principles of the invention.

A system and a method for industrial plant or utility plant flue gas desulfurization, with zero waste water liquid discharge from a wet flue gas desulfurization system utilized therein, are disclosed herein. The wet flue gas desulfurization system is supplied an absorption liquid for contact with a flue gas to absorb flue gas acid gases. Waste water from the wet flue gas desulfurization system is heated under pressure in a heat exchanger to produce heated waste water, which is supplied to a flash vessel to produce steam. The produced steam is supplied to the flue gas upstream of a particulate collection system and the wet flue gas desulfurization system, supplied to the flue gas upstream of the wet flue gas desulfurization system, or supplied to absorption liquid circulated to the wet flue gas desulfurization system.
