After the saturation of Adsorber by admixtures efficiency of evacuation decreases and Adsorber requires regeneration. Regeneration of Adsorber is carried out by heating previously disconnected from the installation Adsorber by a band electric heater. Heating occurs with the simultaneous evacuation by the mechanical and diffusion vacuum pumps. The evacuation stops at the vacuum of less than 10-3 torr in Adsorber. After that Adsorber is attached to the installation and all its pipes are evacuated by the roughing-down pump (Vacuum pump).
Regeneration of H2O & O2 adsorber is carried out after purification of 6 m3 of CO2 (at normal conditions). For this operations the block must be disconnected from the installation. Regeneration is developed by high purity hydrogen blowing through the adsorber from the cylinder while the thermoregulators of the adsorbers are working. The process of regeneration is controlled by the condensation of a moisture on the mirror at the H2O & O2 inlet. Absence of the moisture on the mirror witnesses on the completion of the regeneration. Then, block is disconnected from the hydrogen cylinder, connected to the installation and evacuated for a certain time (near 30 minutes) by Vacuum pump. Then thermoregulator of cartridge then disconnected and block is cooled to the room temperature on the air.
Regeneration of H2O adsorber is carried out simultaneously with the regeneration of the H2O & O2 adsorber. For the regeneration it’s necessary to disconnect the block from the installation and turn on its electric heater. Simultaneously with the heating the blowing through the H2O adsorber by dry nitrogen is necessary. The process of regeneration goes not less than 2 hours, its completion is defined by absence of a steam at the outlet.
