Design specifications for pressure piping for large air separation unit

The liquid oxygen from the main condensing evaporator is compressed by the internal compressed oxygen pump, evaporated and reheated into the main heat exchanger and then out of the cold box as oxygen product. The low-pressure nitrogen is pumped out from the top of the low-pressure tower, and its cooling capacity is transferred to the reflux liquid in the subcooler, which is sent out of the cold box through the main heat exchanger, partially compressed by the first stage of the nitrogen make-up c...

In order to avoid microbial resistance to a single agent, weakening the effect of dosing, the use of two kinds of algaecide in the water circulation system of small air separation unit alternately added. When adding algaecide, first clean the cooling tower tower pool, then add algaecide and maintain 6 to 8 hours without drainage. As the open circulating cooling water and outside contact with a wide range, most likely to breed algae and biological slime. In order to achieve the best effect of ba...
