Air separation operation

In order to achieve the proficiency and correctness of air separation operation, it is not enough to only learn the theoretical knowledge related to air separation, but also need to learn the following knowledge: 1. Be familiar with the flow chart of the set of air separation equipment, and learn the expression methods of instruments, pressure, flow, etc.; 2. Be familiar with the working principle, performance parameters and detailed operation methods of rotating machinery; 3. Be familiar with the salutation, medium and medium of various pipelines on site Quality parameters and the types and functions of each valve.

Structure of water cooling column

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.
