The influence of argon production in air separation equipment on the liquid air inlet

The influence of argon production in air separation equipment on the liquid air inlet
Aug 22, 2023
Author: DEAR AST

In the main air separation tower, the higher the feed inlet of the liquid air, the higher the concentration in the argon enrichment zone of the distillation section. This can reduce the nitrogen concentration in the argon fraction, but also increase the argon content of the downstream liquid. Therefore, more trays are needed below the argon fraction extraction outlet to ensure the purity of oxygen. Therefore, the position of the liquid air inlet should be appropriately raised during argon production.

In the past three years, DEAR Air Separation has obtained six patents in the field of air separation and auxiliary technology: a new main condenser evaporator, energy-saving and safe self-cleaning filters, energy-saving oxygen generators, energy-saving nitrogen water pre cooling systems for air separation, and efficient shell and tube heat exchangers.

The liquefaction of gases can be divided into forward and reverse cycles. The forward cycle process is the absorption of heat from the higher temperature external heat source and the release of heat to the lower temperature external heat source. The reverse cycle is when the mass draws heat from a lower temperature external heat source and releases it to a higher temperature external heat source. The forward cycle converts heat energy into mechanical energy and the reverse cycle converts mechani...

Distillation is using the different boiling points of the two substances to condense the mixed steam and vaporize the mixed liquid repeatedly to achieve gas separation. For a mixed liquid composed of two substances with different boiling points, when the heat absorption part evaporates, the volatile components will evaporate more, while the mixed steam will give off heat and partially condense, the non volatile components will condense more. If the saturated steam with higher temperature is mixed with the saturated liquid with lower temperature, the steam will release heat and partially condense, and the liquid will absorb heat part of it evaporates. If after a round of partial evaporation and partial condensation, the steam and liquid with higher concentration will contact with the steam and liquid with different temperature respectively, and then partial condensation and partial evaporation will occur again. This process will be repeated for many times, and finally gas separation
