The pressure relief of molecular sieve in the purification system is generally rapid in the early stage, not complete and running overtime in the later stage. The pressure relief degree is adjusted by the manual stop valve in front of the pressure relief valve. Through practical adjustment, no matter how it is adjusted, the pressure relief in front is fast, or the pressure can not be exhausted. It is suggested that the valve positioner should be added to the automatic pressure relief valve, and the pressure linear adjustment should be programmed, so that the impact on molecular sieve will be much smaller.

When the same pressure is reduced, the temperature drop of throttling is far greater than that of expansion. This is because the gas does not work externally during throttling, but when the molecular spacing increases, the potential energy of molecules increases, and the kinetic energy decreases correspondingly, reflecting the decrease of temperature. The expansion refrigeration not only increases the potential energy between molecules, but also makes external work to push the impeller to rotate or push the piston to move. All these energies need to reduce the kinetic energy of molecules, so the molecular kinetic energy decreases more and the temperature drop is larger.
