Standardization of cryogenic air separation equipment

According to a DEAR air separation user, during the operation of a set of air separation plant that has been in operation for 5 years, it is found that under the condition that the inlet guide vane does not change, the expansion air volume of the expander gradually decreases, and the rotation speed of the expander gradually decreases, the outlet pressure of the booster end of the expander rises from 0.76MPa to 0.8MPa, the inlet temperature rises from - 110 ° C to - 95 ° C, and the working condition of the chilled water pump is poor.

  Liquefied natural gas (LNG) contains a large amount of high-grade cold energy, which has a high economic value. With the current rapid growth of LNG users in China and the intensification of global energy supply constraints, the rational use of LNG cold energy is particularly important for energy conservation.   As China's demand for LNG increases, more LNG receiving stations will be built in coastal areas, where LNG will be...
