газ очищают в первой стадии (3) сухой адсорбции с оксидом алюминия, который частично отработан;
оксид алюминия в виде частиц с адсорбированными фтор-содержащими веществами отделяют от газа ниже по течению потока от указанной первой стадии адсорбции перед тем, как газ перемещают ко второй стадии (4) адсорбции;
часть отделенного оксида алюминия в виде частиц с адсорбированными фтор-содержащими веществами, удаляют (33) от процесса адсорбции с целью возвращения фтор-содержащих веществ в процесс получения алюминия, а остаток отделенного оксида алюминия возвращают (32) в первую стадию адсорбции; и
газ, после отделения оксида алюминия, подают ко второй стадии сухой адсорбции и там очищают в сущности неотработанным химически активным оксидом алюминия в виде частиц, после чего оксид алюминия в виде частиц отделяют от газа ниже по течению потока от второй стадии сухой адсорбции перед тем, как газ выделяют в окружающую атмосферу, и по меньшей мере часть оксида алюминия, отделенную ниже по течению потока от второй стадии адсорбции, перемещают к первой стадии адсорбции.1. The method of separation during cleaning gas extracted from the process of obtaining aluminum, fluorine-containing substances from gas by adsorption on solid alumina in the form of particles in the process of dry adsorption, characterized in that
the gas is purified with alumina in the form of particles in at least two stages (3, 4), moreover, the aluminum oxide passes through the stages of the adsorption process countercurrent to the gas;
the gas is purified in the first stage (3) of dry adsorption with alumina, which is partially exhausted;
particulate alumina with adsorbed fluorine-containing substances is separated from the gas downstream of said first adsorption step before the gas is transferred to the second adsorption step (4);
part of the separated alumina in the form of particles with adsorbed fluorine-containing substances is removed (33) from the adsorption process in order to return fluorine-containing substances to the aluminum production process, and the remainder of the separated alumina is returned (32) to the first adsorption stage; and
the gas, after separation of the alumina, is fed to the second stage of dry adsorption and therein it is essentially purified by unprocessed chemically active alumina in the form of particles, after which the alumina in the form of particles is separated from the gas downstream from the second stage of dry adsorption before gas is released into the surrounding atmosphere, and at least a portion of the alumina separated downstream from the second adsorption step is transferred to the first adsorption step.
