The cleaned and dried gas is transferred to the propane-butane mixture production plant, and the regeneration gas used for zeolite desorption to the gas purification unit using amine. The device was launched in 1985-1997.

The project stipulates the modernization of treatment facilities using outdated zeolite, its replacement with new modern technological equipment, which will allow to clean 20.0 billion cubic meters of natural gas per year from sulfur compounds and improve its quality.
