Abstract: Solid and liquid, especially high-boiling, impurities are removed from a gas stream containing solvent vapors in such a manner that the gas stream is washed with the condensate of one or more solvent vapors contained in the gas stream, preferably with the fraction which has the greatest affinity for the impurities to be removed. After a distillatory separation of the impurities, as befits the goals of the process, the solvent or solvent mixture used for the washing process is returned again into the process, preferably after it has been removed from the gas stream by condensation and/or adsorption. The gas stream can be returned into a vaporization chamber where it is again charged with solvent vapors.

Abstract: A process for the recovery of solvents is disclosed. A hot carrier gas stream laden with solvent vapors from an evaporation space is compressed, cooled, and expanded with production of work for condensing and separating the solvent. The carrier gas stream lean in solvent vapors is conducted back into the evaporation space after being reheated. The whole of the work arising on expansion is transferred in direct mechanical coupling to one of two or more compression stages for compression of the carrier gas stream laden with solvent vapors. An apparatus for practicing the process is also disclosed.

A wall portion is molded onto the lid. This wall portion has the same length as the side walls, one of which is provided with a recess into which the wall portion, which is slightly narrower than the recess, extends asymmetrically, while leaving free the removal slot and at the same time forming a fixing gap for the packaged material.

Abstract: A process and an apparatus for the recovery of solvents adsorbed from exhaust air containing solvent vapors by an adsorbent is disclosed. A stream of hot inert gas is made to pass preferably, in an alternating manner through two absorbent charges laden with solvent to achieve desorption. The solvent vapors picked up by the stream of inert gas are condensed and separated. The stream of inert gas, lean in solvent vapors, is used as a desorption medium.

Abstract: A process for drying solvent containing material is disclosed. The solvent containing material is passed through a drying chamber containing an inert gas. Inert gas is introduced into at least one lock chamber preceding and/or following the drying chamber. An annular flow of inert gas is produced in the lock chamber. A minor amount of the inert gas required for drying the material is jetted into the lock chamber proximate to the inlet and/or outlet opening of the drying chamber and a mixture of inert gas and sucked-in external air being discharged from the lock chamber in the peripheral region of the annular flow. The major portion of the inert gas is introduced directly into the drying chamber. An apparatus for practicing the invention is also disclosed.

The lid has a castellated cover on its outer side. The segments of the cover, answering to its castellated form, come to an end in a plane at the end of the locking ring and are somewhat smaller in diameter than the diameter of a circle running through inner ends of ribs on and within the locking ring.
