Insurance claims for air separation equipment

  Flow state and heat transfer coefficient Fluid mechanics flow experiments tell us that the fluid flow state can be divided into laminar flow, turbulent flow and excessive flow, laminar flow of each flow beam in an orderly flow, will not interfere with other flow beam. In turbulent flow, the bundles are irregularly intertwined and interfere with each other. Excess flow is a state of flow between laminar and turbulent flow. Of these three flow sta...

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.
