Filed: 1950-01-26
Abstract: 667,312. Distilling zinc. COMPAGNIE DES METAUX D'OVERPELT-LOMMEL ET DE CORPHALIE. Jan. 26, 1950, No. 2099/50. Class 82(i) In a modification of the zinc vapour condenser of Specification 594,487 cooling means are provided for facilitating the formation of small drops of liquid zinc which fall back into the condensation chamber, means being provided for preventing the said small drops from being removed from the condensation chamber with the carbon monoxide gas. Figs. I and II show an arrangement of zinc oven and a condenser which serves a number of retorts A the condenser space being defined by the front wall of the oven, a removable metal plate S, end walls I, liquid metal bath Z and a flat-bottomed water jacket or steam boiler R which constitutes the said cooling means. The metal plate S is suported at its upper border in a sand joint P and is clayed at its other three borders, forming an airtight joint. Cooling at the lower part of the condenser may be limited to the natural radiation from the sheet and side walls. Gases leave the condenser through an orifice in a diaphragm J. A rotor K consisting of end pieces M and blades N on a shaft L enters the said orifice with a small clearance and extends partly above and partly below diaphragm J. Gases leaving the condenser enter the rotorat the periphery of the blades and move towards the axis, the centrifugal force resulting from rotation causing any liquid drops to be thrown to the outside of that part of the rotor in the condensation chamber and to fall back into the metal bath Z. That part of the rotor blades outside the condenser has a larger diameter, and causes a slight suction in the condenser, the pressure in which is slightly lower than in the zinc oven. Specification 657,238 is referred to.

Title: Improvements in and relating to processes for the production of phosphoric acid
IPC: C01B25/20
Filed: 1925-01-23
Abstract: 228,185. Victor Chemical Works, (Assignees of Brassert, H. A., Waggaman, W. H., and Easterwood, H. W.). Jan. 23, 1924, [Convention date]. Phosphorus.-In the reduction of phosphates at high temperature for the production of phosphoric acid and elemental phosphorus, the various parts of the plant employed such as the furnace, flues, downcomer. dustcatcher, and regenerator are each provided with ports and valves by means of which air or oxidizing gases may be admitted to cause combustion of the elemental phosphorus and so control the temperature of the gas stream. Normally the least amount of air is introduced to prevent deposition of phosphorus. The Figure shows plant in which a blast furnace 5 is employed : a resistance or other type of furnace may however be used for the reduction. The blast furnace 5 is provided a.t its lower portion with tuyeres 7 for the introduction of air for the combustion of the fuel and at its upper portion with tuyeres 8 controlled by valves 10. A downcomer 12 conveys the gases from the flue 11, leading from the top of the furnace, to the top of a dustcatcher 23. An inlet pipe 13 with valve 12 passes through the wall of the flue 11 in line with the downcomer. The dustcatcher 23 having a discharge 18 is provided with an air inlet 16 and valve 17. When elemental phosphorus is required, it is at this point that the temperature is allowed to fall sufficiently for phosphorus to be deposited by stopping or restricting the air admitted through the valve 17. The gases leaving the dustcatcher 23 pass through a flue 19 to a regenerator 20. in which most of the phosphorus produced in the furnace is burned by means of air introduced through a pipe 21, the heat of combustion being utilized to heat the air supplied to the tuyeres of the furnace.
