Definitions

• the present invention relates to an apparatus for cooling and purifying air for a cryogenic distillation unit for air.
• a cryogenic distillation air separation apparatus In a cryogenic distillation air separation apparatus, the air is compressed in a compressor and then cooled by direct heat exchange with air in a cooling tower. The cooled air is then purified.
• the purges in the air separation units mainly remove water and CO 2 from the air before entering the cryogenic distillation unit, placed in a cold box.
• a set of valves and pipes allow the transit of the air to be purified and the impure nitrogen used for the regeneration of the purification bottles. This set of valves and pipes is placed "flat" on the ground and has a large footprint. The ratio of the height and length of the set is close to 1
• One of the ways to reduce the width of this set is, through a different piping design, to extend this set.
• the ratio between the height and the width of the set becomes much less than 1.
• the air cooling tower by direct contact with water is installed between the two purification bottles.
• an apparatus for cooling and purifying an air flow comprising a cooling tower by direct contact with water, two purification bottles, each having an axis vertical, a pipe for sending water to the cooling tower, a pipe for sending air to the cooling tower, the tower being disposed between the two bottles, a pipe for sending cooled air from the tower to the purification bottles and a set of valves and pipes for connecting the two bottles to the cooling tower, characterized in that the apparatus comprises a building, ⁇ together being located inside the building and both bottles and the tower being outside the building, the two bottles and the set being placed on either side of a wall of the building, the bottles being placed along the wall.
• the center of the tower seen from above is situated on the median line between the centers of the two bottles seen from above;
• the building also contains at least one compressor and / or at least one turbine and / or at least one distillation column;
• the ratio between the dimension of the assembly in the vertical direction and the dimension in the horizontal direction is less than 1;
• the wall constitutes the longest wall of the building, the building being of rectangular section;
• the ratio of the length of the wall to the width of the building is greater than 2.
• an air separation apparatus comprising a cooling and purification apparatus as described above.
• the air separation apparatus may include a compressor in the building which is an air compressor connected to the cooling tower and / or a turbine in the building, which is an air turbine connected to the bottles and / or a distillation column in the building and connected to the purification bottles.
• the apparatus comprises a cooling tower 1 by direct contact with water, two purification bottles 3A, 3B for purifying air in water and CO 2 and a building 5 containing at least one set of pipes 7 and valves to allow air from the tower 1 to be sent to the bottles 3A, 3B.
• Some of the pipes of the assembly 7 pass through the wall 9 of the building 5.
• the wall 9 is the longest wall of the building 5 which is of rectangular section. The ratio between the length of the wall 9 and the width of the building is preferably greater than 2.
• the ratio between the dimension of the assembly 7 in the vertical direction and the dimension in the horizontal direction is less than 1.
• the two bottles 3A, 3B and the tower are arranged along the wall 9 so that their centers seen from above form a straight line parallel to the wall.
