Pressure piping in air separation cold boxes

Pressure piping in air separation cold boxes
The early design of the air separation cold box in some aspects of operation and performance can no longer meet the requirements of modern production, the main piping in the cold box along the cold phase wall arrangement, this arrangement exists in the cold loss of equipment exacerbated by increased pipeline resistance, pipeline safety decline and the difficulty of setting brackets.

In the condensation evaporator the liquid oxygen is heated to evaporate and the gas nitrogen is cooled and condensed. Both the liquid oxygen and the gas nitrogen are in a saturated state. If the saturation temperature of nitrogen is lower than the saturation temperature of oxygen at the same pressure, the purpose of condensing gas and nitrogen with liquid oxygen cannot be achieved. For this reason the heat transfer temperature difference in the condensing evaporator must be established by the pr...

There is an open heat pump argon extraction process.   The new single column process can only use the open heat pump argon extraction process. Taking 10000cm³ air separation as an example, the main parameters are described as follows.   1、 The quantity of argon fraction is 4200-4300cm3 / h, the content of argon is 10%, the content of nitrogen is 1%, and the rest is oxygen.   2、 The theoretical plate number of the whole column is about 100.   3、 Two heat pump dist...
