Filed: 1976-08-10
Abstract: 1511458 Removing settled solids S J ENZMANN 10 Aug 1976 [11 Aug 1975] 33306/76 Heading BID A method for separating solid particles from a liquid, e.g. metal particles from a coolant used in machining, comprises continuously passing the contaminated liquid through a tank wherein it is floated on a vehicle liquid of greater specific gravity, also continuously passed through the tank, the solid particles settling into the vehicle liquid. Suitable apparatus for carrying out the method comprises a tank 10 having (i) a liquid inlet 27 and a liquid outlet 42 for contaminated liquid, the inlet and outlet being adjacent opposite sides of the tank and disposed above the bottom thereof; (ii) an inlet 22 and an outlet 18 for a flushing liquid, e.g. water, of greater density than the contaminated liquid, again positioned on opposite sides of the tank for flow of the flushing liquid 13 across the lower part of the tank beneath the flowing layer 31 of the contaminated liquid to collect and remove solid particles settling therefrom; (iii) a conduit 32 for removal of the flushing liquid having outlet 32 as its inlet and having its outlet, e.g. variable height weir 40, arranged at a level above the tank floor, suitably above liquid outlet 42; and, (iv) means, e.g. conduit 37, for removing the flushing liquid and passing it to one or more hydrocyclones 58 for removal of the collected solid particles. Separation of the solid particles may be aided by heating the contaminated liquid, e.g. by heater 68, and by revolving magnetic drum 64 with associated scraper 66. Suitably, the chamber 34 into which the flushing liquid feeds over weir 40 and a similar chamber 45 into which the treated liquid feeds from outlet 42 each have two outlets 37, 52 and 44, 47, respectively. The lower of each pair 37, 44 is valve controlled so that a level of liquid is maintained in the chambers 34, 45 resulting in further gravity separation of the liquids therein for removal of lighter components by upper outlets 52, 47. The flushing liquid issuing from the hydrocyclones may be recycled to inlet 22. Outlet 42 of treated liquid is valve controlled to enable adjustment of the residence time of contaminated liquid.

Abstract: 660,113. Gas separation. DIRECTIE VAN DE STAATSMIJNEN IN LIMBURG. Dec. 18, 1947 [Feb. 22, 1944], No. 33512/47. Class 8 (ii). In a process for the separation of a gaseous mixture e.g. coke oven gas by fractional condensation in a rectification column 10, Fig. 7 under superatmospheric pressure, say thirty atmospheres and cooling the mixtures in countercurrent heat exchange relation with the separated ethylene, methane, carbonmonoxide nitrogen and hydrogen in exchangers 2, 4, 7 whilst vaporizing by expanding at a valve 17 part of the separated methane to a pressure intermediate one and thirty atmospheres and further expanding this vaporized methane at a turbine 18 and also vaporizing the remaining methane by expanding it to one atmosphere at a valve 16, the proportion of the methane chosen for expansion at the valve 17 and the expansion pressure are such that at every point of the temperature trajectory traversed by the gaseous and liquified fractions a surplus of cold remains on that part of the trajectory of the gases below the vaporization temperature at least equal to the deficit of cold on the trajectory above this temperature, and that the minimum value of the hypothetical work necessary to transfer the cold obtained by such vaporization is at least 90 per cent of the maximum. The cold needed for the cooling of the coke oven gas mixture from-90 to -190‹C is shown by the complete line in Fig. 8, and the cold set free by returning fractions is shown by the broken line. The area bounded by the curves between any two temperatures gives the cold deficit or surplus according to the relative positions of the curves. Thus between -90 and -160‹C; i.e., during the liquifaction of the ethylene and part of the methane there is a cold deficit of 104À8-366À6, i.e., 471À4 calories per molecule of gas, which is compensated by a surplus of 474À2 calories per molecule due to vaporization of methane between 160 and 177‹C. Cold needed for condensation of gas below 177‹ is obtained from an outside source e.g., liquid nitrogen at high pressure expanded at a valve 13. The optimim pressure to which the methane is expanded at the valve 17 is seven atmospheres. U.S.A. Specification 2,122,238 is referred to.
