Abstract

519,856. Removing hydrogen sulphide from gases; electric automatic control systems. COURTAULDS, Ltd., and THOMAS, R. S. Oct. 4, 1938, No. 28800. [Class 55 (ii)] [Also in Groups XXXV and XXXVIII] In a continuous process for removing hydrogen sulphide from waste gases by washing them with an aqueous suspension of an oxide or hydroxide of iron, an oxide or hydroxide of manganese and sufficient lime to secure a pH value between 9.0 and 11.5 lime is added to maintain this value by a jet of water flowing into a suspension of lime to displace it into the washing liquid and the rate of addition of lime is varied when required by altering the rate of flow through the jet, for example, by a change of head. The Figure shows a washing tower 1 through which the washing liquid is circulated by a pump 7 a lime suspension in a tank 23 overflowing into the storage tank 5 according to the rate of water supply through a jet 21 required to maintain the pH value. The apparatus provides for automatic adjustment of the height of the jet 21 in respect of the constant level in a tank 22. A portion of washed gases passes through a chamber 9 to react with a soluble lead salt with which an absorbent film is impregnated. This film is passed between a light 11 and a photo-electric cell 12 the resulting current from which operates an amplifier 14 and recording milliammeter 15. The jet head may be adjusted according to the recorded indications and a relay 16 may operate a reversing switch 17 whereby a motor 19 which normally operates periodically to raise the jet may be caused to lower it and so increase the supply of lime suspension when the proportion of hydrogen sulphide in the washed gases is excessive. Specifications 519,229, [Group XL], and 519,274 are referred to.
