Abstract: Disclosed herein is a method and apparatus for recovering hydrocarbons from polyolefin plants. A method of the present disclosure includes introducing a hydrocarbon-containing inert gas from a residual monomer separation unit of a polyolefin plant into a condensation and separation device, condensing hydrocarbons from a hydrogen-containing inert gas in the condensation and separation device, separating the condensed inert gas into a condensed hydrocarbon-containing product and purified inert gas in the device, and sending the condensed hydrocarbon-containing product to a downstream further separation device for removal of dissolved gasses therefrom. A device of the present disclosure includes a condensation and separation device for condensing hydrocarbons from an inert gas and separating condensed hydrocarbon-containing inert gas into a condensed hydrocarbon-containing product and a purified inert gas, and a further separation device connected downstream for purifying the condensed hydrocarbon-containing product originating from the condensation and separation device by separating off dissolved gases.
