Abstract
255,141. Jackson, W. J., Mellersh-, (Koppers Co.). April 14, 1925. Materials and compositions for purifying.-Fuel gases are purified from hydrogen sulphide &c. by washing them first with a suspension of a metallic compound in a liquid of relatively low alkalinity and then in a similar suspension of higher alkinity. The liquid in the first case is preferably a 1 per cent solution of sodium carbonate containing in suspension about 1 per cent of pulverized hydrated ferric oxide, while the second liquid contains 3 per cent sodium carbonate. The apparatus comprises two absorbers A<1>, A<2> connected with four aerators T<1> - - T<4> and two sumps W<1>, W<2> by valved pipes so that the flow of the gases through the absorbers may be reversed, and the absorbers supplied with either a solution of low alkalinity from the aerators T<1>, T<2> or with a solution of higher alkalinity from the aerators T<3>, T<4>. In a modification, while the alkalinity of the solution is maintained in the washing stages, the spent liquid entering the revivification stage is maintained in a neutral or slightly acid condition by the addition of acidic iron compounds, e.g. ferric sulphate or chloride acids, acid salts or sulphur dioxide. The solution may he heated to 85‹ F. as described in Specification 255,140, and the absorber used may be that described in Specification 255,142; and the aerator may comprise a tubular fabric suspended with freedom of movement as described in Specification 255,139. Free sulphur accumulating in the compartments T<1> - - T<4> may be removed by cutting out one of the compartments and passing the sulphur after settling to a centrifuge C or a filter, the sulphur then being separated from the iron compounds which are returned to the system. Alternatively the sulphur may be removed with the suspension, fresh suspension being supplied to the compartments which are kept working continuously. The sulphur may also be removed from the alkaline solution by flotation, anti-foaming agents such as kerosene being added. The ferric oxide is preferably prepared by pulverizing bog ore. Specifications 190,116 and 238,172 are also referred to.
