Environmental protection technology for air separation equipment

(1) Can be based on the cold box outside the piping diagram provided by the equipment manufacturer and the relevant national standards and norms for industrial piping installation. For heavier weight valves, small lifting tools can be used to temporarily support them. When the piping is good, use fixed brackets to support. (2) Liquid discharge mains should be installed with compensation parts. (3) The aluminium pipe leading out of the cold box with its welded pressure plate and its seal ring s...

In the air separation unit, the water cooling column is a hybrid heat exchange equipment which uses the crude nitrogen to reduce the temperature of the cooling water from the air cooling column after cooling air, so as to provide the air cooling column with recycling. In the water cooling column, the crude nitrogen from the reversible heat exchanger (or accumulator) is 27-28 ℃ and the relative humidity is about 30%, while the temperature of the cooling water from the air cooling column is 35-45 ℃. When the crude nitrogen meets the hot water sprayed, it absorbs heat, thus reducing the water temperature. Generally, the structure of water cooling column is packed column, cyclone plate column and sieve plate column.
