Abstract: 811,162. Purifying phenolic waste liquors. COAL INDUSTRY (PATENTS) Ltd. Oct. 21, 1955 [Oct. 29, 1954], No. 31333/54. Class 111. An activated sludge process for treating phenolic waste liquor, e.g. waste ammoniacal liquor containing phenols from coal carbonisation processes, to reduce the phenol content, consists in subjecting the liquor to bacteriological oxidation by conditioned activated sludge at a temperature between 30‹C. and 70‹C. preferably between 35‹C. and 45‹C., the liquor being previously, preferably immediately previously, heated or cooled to the required temperature. Liquor flows through a cooler 2 to a head tank 3 supplying directly the first and third of reaction tanks 4-11 separated by baffles 4C-10C alternately permitting underflow to the next tank. Sprayers 4D ... 11D prevent undue frothing and compressed air delivered at 4A ... 11A and 4B ... 11B effects aeration. The last tank 11 delivers to a settling hopper 12 through an inlet pipe 13. Sludge collects in an aerated tank 14 for return to the reaction tanks, the action being continuous if the tank is always open to the hopper 12. To prepare the sludge, dilute liquor in increasing concentrations is added periodically to fertile garden soil : water is then added and while further liquor is added the temperature is raised to the desired figure.

Patent GB-864139-A (GB)
Title: Production of maleic anhydride
IPC: C07C51/56
Filed: 1958-10-03
Abstract: Maleic anhydride is prepared by contacting an aqueous maleic acid solution with maleic anhydride vapour supplied from a boiling liquid body of anhydrous maleic anhydride thereby converting said maleic acid into maleic anhydride vapour, immediately condensing and separating the resulting maleic anhydride vapour from the water vapour and collecting said condensed maleic anhydride in the substantial absence of water.  The maleic anhydride vapour may be supplied from the liquid body in which the product is collected and may be maintained under reflux.  The maleic acid solution is preferably preheated and may contact the anhydride vapour as a spray or thin film.  In a preferred embodiment the contact zone has at least 2 distinct sections, the temperature of one section being maintained below the boiling point of maleic anhydride but above that of water at the prevailing pressure, and that of the other at or slightly below the boiling point of water, the aqueous maleic acid being fed to the first section at a point intermediate therein, the water-vapour being removed from the exit end of the lower temperature section and the maleic anhydride vapour condensed in the higher temperature section.  Operating pressures of 10-760 mm. Hg may be used.  The aqueous maleic acid feed may contain about 5-80% by weight of maleic acid.

[Also in Group XXIX] A fluid-pressure control valve is constructed by increasing the outside diameter of a part 9a of the tubular valve member 9 to equal the effective diameter of the seat of the valve 10 and slidably and fluid-tightly fitting the increased diameter part through the passage 5. The tubular member is first passed through a removable wall 7 via the passage 6 of slightly smaller diameter than 5 and the valve ground on its seat, which slightly increases the effective diameter of the seat. The part 9a is then increased to the diameter of the seat by coating it with nickel or chromium, e.g. electrically or by spraying. The increase in diameter may be effected by a metal sleeve, a hard rubber or thermo-set plastic material or by spraying lacquer on it. In this way the tubular valve member is accurately balanced with respect to the inlet and outlet pressures in chambers 4 and 2 respectively.
