A scrubber system having a lower body, a scrubber located in the lower body, the scrubber having a reactor and a wet treatment performer connected to the reactor, the scrubber being configured in the form of a chiffonier, an upper body located on the lower body, and a pump located in the upper body, wherein the pump pumps a harmful gas from a manufacturing device into the reactor, and the scrubber purifies the harmful gas and discharges a purified gas to the outside of the upper body.

Provided is a recombinant microorganism having enhanced activity of at least one protein selected from 6-phosphogluconate dehydrogenase (6PGD) and foldase protein PrsA, a method of reducing a concentration of a fluorine-containing compound in a sample by using the recombinant microorganism, and a method of preparing the recombinant microorganism.

Provided is a recombinant microorganism including an exogenous gene encoding a bacterial cytochrome P450 protein or a variant thereof, a composition including the recombinant P450 protein or the variant thereof, which is used for removing CH.sub.nF.sub.4-n (n is an integer of 0 to 3) in a sample, and a method of reducing a concentration of CH.sub.nF.sub.4-n in the sample.

A multi-plate scrubber is provided, and more particularly, a multi-plate scrubber including plates having different shapes to purify polluting gas is provided. According to the multi-plate scrubber, the polluting gas is effectively purified by increasing chances of contact between the polluting gas and circulating water by using various plates having different shapes.

A microorganism including a foreign gene encoding a protein having a hydroxylase activity that reduces the concentration of CH.sub.nF.sub.4-n (n is an integer of 0 to 3) in a sample, as well as a composition including the microorganism or lysate thereof, and a method of reducing the concentration of CH.sub.nF.sub.4-n in a sample using the microorganism or lysate.

Provided are an exhaust gas decomposition system, a complex exhaust gas decomposition system, and a method of decomposing an exhaust gas, wherein the exhaust gas decomposition system includes at least one of a bioreactor system that includes at least one of a bioreactor vessel; at least one of a first inlet supplying a first fluid into an interior of the vessel; at least one of a first outlet discharging the first fluid to an exterior of the vessel; at least one of a second inlet supplying a second fluid into the interior of the vessel; at least one of a second outlet discharging the second fluid to the exterior of the vessel; and at least one of a sparger located in the interior of the vessel and connected to the second inlet

Disclosed herein is a system for recovering olefins from a vent stream comprising an absorber; and a stripper; where the absorber and the stripper are in a recycle loop; and where the absorber is operative to treat a vent stream with a solvent to remove more than 99 wt % of a halogenated by-product contained in the vent stream and to recover 90 to 95 wt % of olefin molecules present in the vent stream; and where the stripper is operative to remove more than 99 wt % of the halogenated by-products present in the solvent; and where the solvent is recycled to the absorber.

This disclosure provides a waste battery thermal desorption treatment system. The waste battery thermal desorption treatment system includes: a rotary kiln, having a feed port, thermal desorption cavity, heating cavity, discharge port, and first exhaust port; a dust removal apparatus, including a housing with a gas inlet port and a second exhaust port, and a dust removal structure disposed in the housing configured to collect impurities in a gas exhausted from the first exhaust port; a condenser, in communication with the second exhaust port, to condense an electrolyte constituent; and an adsorption column having a defluorination agent for dry defluorination on remaining constituents in the gaseous exhaust. This disclosure resolves the problem of low recycling efficiency of waste lithium batteries in the prior art.

The present invention relates to a vacuum pumping and abatement system for evacuating processing gas from a process chamber and removing noxious substances from the processing gas. The present invention also relates to a method of purging a vacuum pumping arrangement. The present invention seeks to reduce the cost of ownership and operation and carbon footprint of such systems, by providing a vacuum pumping and abatement system for evacuating processing gas from a process chamber and removing noxious substances from the processing gas, comprising a vacuum pumping arrangement for evacuating processing gas from a process chamber; a source of compressed air for purging the vacuum pumping arrangement during evacuation; and a burner for receiving processing gas and compressed air from the vacuum pumping arrangement and removing noxious substances therefrom by burning the processing gas in oxygen wherein at least some of the oxygen that supports combustion is derived from the compressed air.
