The Ferrox process is one of the wet processes for removing hydrogen sulfide from crude gases, and it is based on the following reactions, that is, the absorption of hydrogen sulfide with an aqueous suspension of ferric hydroxide, and the removal of sulfur from iron sulfide by an oxidation with air.　2Fe(OH)_3 + 3H_2S = Fe_2S_3 + 6H_2O　2Fe_2S_3 + 3O_2 + 6H_2O = 4Fe(OH)_3 + 6S　In practice, however, the removal of hydrogen sulfide by this process has not always been satisfactory, and the regeneration of the absorption liquor has not so easily accomplished.　The authors made the following studies both fundamental and industrial with the object of improving the process by eliminating the above disadvantages.　... Part 3; Study of chemical engineering on the Ferrox process.　By analyzing the fundamental data obtained on the models of the packed and the stepwise packed towers, in which hydrogen sulfide in the crude gas is absorbed with the neutral suspension of ferric hydroxide, several experimental equations representing a quantitative relationship between the gas and the liquor were derived. These equations could be used as the data necessary for the design of the large absorption towers.
