ABSTRACT OF THE DISCLOSURE A condenser for separating solvent vapors from non-con- densable gases. The condenser includes an outer shell, a middle shell inside the outer shell, end an inner shell inside the middle shell. The shells are coaxial and the middle shell is open at the bottom. Mixed solvent vapors and non-condensing gas pass downwardly through an annular space between the inner and middle shells. There is a condensate receiving chamber in the outer shell below the lower end of the middle shell. A cold trap is mounted in the upper portion of the condensate receiving chamber. Coolant is introduced into the cold trap to cool the cold trap. Helical tube means mounted on the cold trap receives the coolant from the cold trap. The helical tube means extends upwardly through the annular space between the inner and middle shells and discharges into an upper portion of the inner shell, and is removed from the inner shell. Condensate is withdrawn from the chamber in the lower portion of the outer shell. The non-condensable gas passes upwardly from the lower end of the middle shell through an annular space between the middle shell and the outer shell into a collecting space in an upper end portion of the outer shell. The non-condensable gas is withdrawn from the collecting space.
