The invention relates to a bath condenser with a condenser block (1) that has evaporation passages (8) for a liquid and liquefaction passages (2) for a heating medium and at least two circulation sections (7) that are located vertically on top of one another. The evaporation passages (8) each have on the lower end of a circulation section (7) at least one entry opening ( 9) for the liquid and on the upper end of a circulation section ( 7) at least one exit opening (10), for each circulation section (7) there being a liquid storage tank (15) that is flow-connected to the entry opening (9) and the exit opening ( 10) of the circulation section (7) and that has a gas offtake (18). The inlet into the gas offtake (18) is not located in the area in front of the side (12) of the circulation section ( 7) in which the exit opening (10) of the circulation section (7) is located.

The invention claimed is: 1. Bath condenser with a condenser block that has evaporation passages for a liquid and liquefaction passages for a heating medium and at least two circulation sections that are located vertically on top of one another, the evaporation passages each having on the lower end of a circulation section at least one entry opening for the liquid and on the upper end of the circulation section at least one exit opening, for each circulation section there being a liquid storage tank that is flow-connected to the entry opening and the exit opening of the circulation section and that has a gas offtake, wherein, for at least one circulation section, the inlet into the gas offtake (18) is not located in a volume horizontally adjacent to the condenser block (1), the volume being bordered, horizontally, by the side (12) of the circulation section (7) in which the exit opening (10) of that circulation section (7) is located and extending horizontally away from the condenser block, and, vertically, by sheets (16) that are aligned perpendicular to the side (12) of the circulation section and aligned to the top and bottom of the circulation section. 2. Bath condenser according to claim 1, wherein the inlet into the gas offtake (18) is located above the volume horizontally adjacent to the condenser block. 3. Bath condenser according to claim 2, wherein the inlet into the gas offtake (18) is located at the height of the overlying circulation section (7). 4. A bath condenser according to claim 1, wherein the inlet into the gas offtake (18) is located in a volume horizontally adjacent to the condenser block (1) that is bordered by a side ( 11) of the condenser block (1) that has no entry opening or exit opening, and by two sheets that each include one vertical edge of the side (11) and that are aligned perpendicular to the side ( 11) of the circulation section and aligned to the top and bottom of the circulation section. 5. A bath condenser according to claim 1, wherein the inlet into the gas offtake (18) is located in a volume horizontally adjacent to the condenser block (1) that is bordered by the side of the condenser block (1) opposite the side (12) of the circulation section (7) in which the exit opening (10) of the circulation section (7) is located, and by two half-planes that each include one vertical edge of the opposite side and that are aligned perpendicular to the opposite side of the circulation section and aligned to the top and bottom of the circulation section. 6. A bath condenser according to claim 1, wherein at most two sides (12) of the condenser block (1) are provided with entry (9) and/or exit openings (10). 7. A bath condenser according to claim 6, wherein all entry (9) and exit openings (10) are located on the same side ( 12) of the condenser block (1). 8. A bath condenser as claimed in claim 1, wherein a collector (13) with a liquid feed line (22) and a gas offtake (18) that is horizontally adjacent to at least two circulation sections (7) is attached to one side (12) of the condenser block (1) in which the entry (9) and/or exit openings (10) are located. 9. Bath condenser according to claim 8, wherein the collector (13) horizontally adjacent to at least two circulation sections (7) is divided into stages (15), two adjacent stages ( 15) being connected to one another via one liquid line (17, 30) and one gas line (18) on the flow side. 10. Bath condenser according to claim 9, wherein two adjacent stages (15) are connected to one another via an overflow pipe ( 30) for liquid transport. 11. A bath condenser according to claim 1, wherein the condenser block has a rectangular cross-section and is located in a round tank. 12. A bath condenser according to claim 1, wherein the condenser block (1), liquid storage tanks (20) and separation spaces (21) that are connected to the liquid storage tanks (20) form in a plan view, a hexagon. 13. A bath condenser according to claim 1, wherein the condenser block (1), liquid storage tanks (20) and separation spaces (21) that are connected to the liquid storage tanks (20) form in a plan view, an octagon. 14. In an air separation system comprising a high pressure column, low pressure column and a main condenser for vaporizing oxygen in the low pressure column and liquefying nitrogen in the high pressure column, the improvement wherein the main condenser is in accordance with claim 1. 15. A method of separating air, comprising fractionating air in a system according to claim 14. 16. A bath condenser of claim 8, wherein the collector ( 13) with a liquid feed line (22) and a gas offtake (18) is horizontally adjacent to the entire side (12) of the condenser block (1) in which the entry (9) and/or exit openings ( 10) are located. 17. A bath condenser of claim 1, wherein the path from the exit opening to the gas offtake inlet is deflected at least once such that liquid entrained in a gas-liquid mixture along such path is separated more easily from the gas.
