What impact does the air separation equipment have on the device when extracting rare gases

When extracting rare gases from an air separation plant, additional equipment must be provided. Most of these devices operate at low temperatures, which inevitably leads to an increase in cold loss, so it is necessary to increase the cooling capacity. However, the cooling capacity of all low-voltage equipment is critical. Therefore, in addition to considering how to increase the cooling capacity, it is necessary to use the cooling capacity reasonably and reduce the cooling loss during design. During operation, great attention should also be paid to this issue. The cooling capacity should be reasonably distributed according to process requirements to minimize cooling losses caused by leakage or excessive temperature differences, otherwise production will be impossible due to insufficient cooling capacity.

When extracting a rare gas, distillate gas or liquid containing the rare gas must be extracted from the relevant parts of the distillation column, and then returned to the distillation column after separation. Some require extraction of liquid air, liquid nitrogen, or medium pressure gas as a cold or heat source for additional equipment. In this way, certain changes will inevitably occur in the reflux ratio in the main tower, and it will also affect the distribution of rare gases in the distillation tower and the operating conditions of the rare gas tower. Therefore, in addition to considering the selection of a reasonable extraction position and number of trays during design, it is important to make the operation as stable as possible during use. After the parameters of each part of the main tower have stably met the requirements, slowly and carefully start the equipment for extracting rare gases.

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
