Abstract
This method is used in the chemical industry, and utilizes the hydrocarbon-containing effluent gases. It ensures a high degree for conversion of hydrogen chloride into chlorine over a long period of time without any large power, or sulphuric acid expenditures, or the need for any organic solvents.Description : the hydrogen chloride is oxidized to chlorine with oxygen, at a correlation of oxygen and hydrogen chloride between 0.5 and 2, temperatures between 300 and 450 degrees C, pressures between 1 and 10 atmospheres, and in the presence of a chromium oxide catalyst. The reactor, in which the hydrogen chloride is oxidized, is prepared from nickel and is coated with nickel. The derived product (as a result of the oxidation gas, containing mainly water, non-reacting hydrogen chloride, oxygen and vapours from chromium compounds), is cooled quickly and then washed in water, during which the chromium is extracted in the liquid phase. The remaining part of the gas is washed again with water to absorb non-reacting hydrogen chloride, and remove it as a hydrochloride. The remaining part of the gas is washed with sulphuric acid to remove water from it. After the dehydration, a part of the derived gas remains, containing mainly chlorine and a non-reacting oxygen, which is subjected to compression and cooling, while the chlorine is liquefied and extracted as a liquid phase from the remaining part of the extracted gas, containing mainly oxygen. Part of this residual part of the gas is recycled to the oxidation stage of the hydrogen chloride.
