Abstract

570,396. Gas-washers. CLAPHAM, T. A., and BARWICK, J. C. April 8, 1943, No. 5659. [Class 55 (ii)] In coal-gas-purifying apparatus comprising a scrubber to which washing liquid is delivered by a gas lift pump, means are provided for removing naphthalene from the gas prior to its delivery to the pump. A naphthalene extractor 14, Fig. 2, comprises a number of superposed bubbling chambers 22 each open at the top, but closed by the bottom wall 23 of the chamber above, the bottom wall of each chamber being provided with a short pipe 25 over which is arranged a hood 26 having a serrated bottom edge 27. Each hood is provided with internal ribs 28 which rest on the top edge of pipe 25 and also with locating surfaces. The bottom wall of each chamber, except the lowermost, carries a downwardly-extending oil feeding pipe 29 which extends to a sealed position close to the bottom wall of a lower compartment. The oil feeding pipes in the various chambers are arranged in staggered relationship. The top chamber has a gas outlet passage 31 arranged in the cover-plate 32, and the gas is fed into the bottom of the apparatus through the conduit 21. The oil inlet passage 33 communicates with an oil supply system 34, and the bottom chamber has an oil outlet passage 35. The stack of chambers may be mounted on a stand 36. A heavy oil fraction of coal tar (green oil) mixed with from 3 to 6 per cent of benzene may be used. In the gas-washer shown in Fig. 1, gas is passed from an inlet pipe 11 to an outlet pipe 12, a portion of the scrubbed gas being withdrawn from pipe 12 through a conduit 13 to the naphthalene extractor 14 from which the naphthalene-free gas is conducted through conduit 15 to the compressor 16 and thence by pipe 17 to some or all of the gas-lift pumps, in the former case the remaining pumps being operated by compressed air as described in Specification 570,397. If the washer is followed by a naphthalene extractor, the conduit 13 from the extractor outlet may lead directly to pipe 15. The naphthalene may, alternatively, be removed by shock cooling or other physical methods.
