METHOD FOR REGENERATION OF SATURATED SOLUTION OF MOISTURE ABSORBING AGENT Russian patent published in 2016 - IPC B01D53/14 

FIELD: chemistry.

SUBSTANCE: method for the regeneration of the saturated solution of a moisture absorbing agent, including the output of natural and petroleum gases of a saturated absorbent from a drying installation absorber and its processing in two stages, with processing being carried out with a specific flow in the above-membrane space, characterised by the fact that at the first stage the process is carried out with the application of 2 membrane installations at 18-25°C, with the separation of ions Ca²⁺ taking place in the first membrane installation, and Cl^- ions - in the second installation, and the second stage of the process is carried out with the application of 2 other membrane installations at 50-55°C. The claimed method can be widely used for the utilisation and regeneration of the wastes of the chemical technology, applied in the oil-, gas-extracting and refining industry, as it makes it possible to re-use the desiccant of natural and petroleum gases in a waste-free and economical way.

EFFECT: increased quantity and effectiveness of absorbent regeneration.
