    摘要： For the low-temperature separation of a gaseous mixture containing essentially hydrogen, C.sub.1+ -hydrocarbons, and carbon monoxide, resulting in a purified gaseous mixture to be processed, after the low-temperature separation, in methanol synthesis, the gaseous mixture is cooled and subsequently fed to a scrubbing column to scrub out the C.sub.1+ -hydrocarbons with liquid CO. A product containing essentially hydrogen and carbon monoxide is obtained at the head of the scrubbing column. The resultant liquid CO, loaded essentially with the C.sub.1+ -hydrocarbons, is withdrawn as the sump product from the column and introduced into a C.sub.1+ -CO separating column.

    摘要： A long-distance truck or trailer cabin in which a bin is arranged above the windshield in an angular space between the roof and the front wall of the cabin. The bin is confined by a horizontal bottom and a rear end wall. The bin, furthermore, has a sliding curtain arranged at the front wall and the side walls to cover the side windows and the windshield. The curtain, moreover, is suspended in a continuous runner. A compartment is provided in a recess in the horizontal bottom at substantially the center of the cabin. The compartment has a downward-directed opening and a cover which is pivotally supported by horizontal hinges. The runner extends across the opening section of the compartment. The cover may be provided with a shape conforming to a bulging cylindrical shelf or cupped saucer. A curtain, furthermore, may part vertically at substantially the center of the cabin.

    摘要： In a process proposed for purification of a gas stream at elevated pressure by nitrogen scrubbing, the gas stream to be purified and the nitrogen scrubbing stream are initially cooled to low temperatures. The gas stream is then scrubbed with liquid nitrogen and the purified gas stream is mixed with cooled, high-pressure nitrogen to form a mixture in which nitrogen accumulates partly as a liquid phase. The mixture thus formed is then heated and the liquid nitrogen contained therein is evaporated. Prior to scrubbing, either the nitrogen scrubbing stream itself or a partial stream of the nitrogen scrubbing stream or another process stream under a pressure lower than the working pressure of the nitrogen scrubbing step is at least partly condensed and then pumped to a higher pressure. The condensation of this low-pressure stream provides a reduction in the temperature difference at the cold end of the heat exchangers upstream of the scrubbing step resulting in the reduction of the energy requirements of the process.
