ADSORBER Russian patent published in 2023 - IPC F25B37/00 

FIELD: adsorption technology.

SUBSTANCE: invention can be used in gas processing, chemical and other industries. The adsorber contains a double-necked cylinder with an adsorbent, shut-off devices for raw gas inlet and purified gas outlet. A gas outlet tube is installed inside the cylinder. The inlet end of the tube is located at a predetermined distance from the purified gas outlet neck and is equipped with a filter, mainly a mesh filter. The outlet end of the tube is brought out through the neck of the purified gas outlet, which is connected in series with the fine filter and further with the gas analyser. The gas analyser has the ability to continuously supply a signal about the volume fraction of carbon dioxide in the purified gas to the comparison and calculation unit, and the comparison and calculation unit is connected to the recording device.

EFFECT: accounting of degradation of properties of the adsorbent, which occurs due to its abrasion during operation, by adjusting the time of the protective action of the adsorber and eliminating cases of release of purified gas from the adsorber with an impurity content above the permissible values.
