<p>A description is given of a device (1) for purifying contaminated gas, in particular air which is contaminated with solvent vapour, at least comprising a housing (2) with an inlet (3) for contaminated gas and an outlet (6) for purified gas, and gas-displacement means (15) for forming a flow of gas from the inlet (3) to the outlet (6), the device (1) furthermore comprising at least one container (11) for accommodating an absorption agent, which container (11) is in open communication with the flow of gas in order to deliver gaseous absorption agent to the flow of gas, in the absence of outlet means for used liquid absorption agent. Furthermore, a description is given of a method for purifying contaminated gas, such as air which is contaminated with solvent vapour, in which the contaminated gas is withdrawn from an environment and is brought into contact with the gas or vapour phase of an absorption agent and the resultant gas mixture containing purified gas is then discharged. <IMAGE></p> |
