Recovery of carbon from aqueous dispersions

1406968 Carbon; recovery from aqueous dispersions TEXACO DEVELOPMENT CORP 23 Nov 1973 [29 Dec 1972] 54560/73 Heading C1A Particulate carbon is recovered from a water dispersion by mixing the dispersion in a mixing zone with a first hydrocarbon oil having a density less than that of water in an amount just sufficient to render the carbon dry and fluffy, allowing the resulting mixture to settle in a settling zone to permit the carbon to rise to the surface of the water, adding a second hydrocarbon oil to form a hydrocarbon oil-carbon dispersion on the surface of the water, and separating the hydrocarbon oil-carbon dispersion from the water. The second hydrocarbon oil may be a petroleum residium, optionally mixed with naphtha. The first hydrocarbon oil may be a petroleum fraction boiling within the C 5 - naphtha range (optionally naphtha) and may be flashed from the hydrocarbon oil-carbon dispersion after its removal from the settling zone. The residue from the flashing process may be subjected to partial oxidation for the production of a gas composed principally of carbon monoxide and hydrogen. The C 5 -naphtha fraction from the flashing process may be recycled to the mixing zone. The amount of the first hydrocarbon oil used may be between I and 2 times the oil adsorption number of the carbon (1À5-10 lbs. of oil per lb. of carbon). The second hydrocarbon oil may be added in an amount sufficient to form a dispersion containing from 1 to 5% by weight of carbon. The watercarbon dispersion may contain between 0À5 and 4% by weight of carbon. The hydrocarbon oil-carbon dispersion may be separated at 180‹ to 475‹ F. The process may be used to recover carbon from aqueous dispersions formed in scrubbing synthesis gas with water.

Coal liquefaction

COAL LIQUEFACTION ABSTRACT OF THE DISCLOSURE A coal liquefaction product is separated into an essentially solids-free stream and a solids-containing stream including the coal ash. The solids-containing stream is hydrotreated, in the absence of added catalyst, and valuable clean fuel components stripped from the hydrotreated stream. The combustibles content of the stripped solids-containing stream is reduced by hydro-treatment, prior to stripping.

PROCESS AND PLANT FOR THE TREATMENT OF SLUDGE, PARTICULARLY COAL SLUDGE

Procédé de traitement de boues, en particulier de boues de charbon, par addition à la boue d'un additif à action sélective et introduction de cette boue dans un appareil séparateur. La particularité essentielle de ce procédé est qu'on opère dans l'appareil séparateur 5 pour mélanger intimement la boue avec son additif. L'installation comprend essentiellement l'appareil séparateur 5 équipé de moyens 1, 2, 3, 4 pour l'amenée de la boue ainsi que pour les évacuations séparées du corps solide 21 et du centrifugent 22, et d'un appareil 6, 7, 8, 9 pour l'amenée de l'additif à la boue, de préférence en des quantités proportionnelles. L'additif est par exemple constitué d'hydrocarbures, notamment d'huiles usées. On obtient ainsi un produit qui a une teneur en cendres relativement faible. Process for treating sludge, in particular coal sludge, by adding a selective additive to the sludge and introducing this sludge into a separating device. The essential feature of this process is that one operates in the separator apparatus 5 to intimately mix the sludge with its additive. The installation essentially comprises the separator apparatus 5 equipped with means 1, 2, 3, 4 for supplying the sludge as well as for the separate evacuations of the solid body 21 and of the centrifuge 22, and of an apparatus 6, 7 , 8, 9 for supplying the additive to the sludge, preferably in proportional amounts. The additive consists, for example, of hydrocarbons, in particular waste oils. A product is thus obtained which has a relatively low ash content.

Processes and apparatuses for recovering clean water and solids from aqueous solids

Aqueous solids are mixed with a low viscosity, relatively volatile, water- immiscible light fluidizing oil to obtain a mixture which will remain fluid and pumpable after removal of substantially its entire water content. The mixture of solids, water and fluidizing oil is subjected to a dehydration step by heat evaporation whereby substantially all of the water and at least part of the light oil are evaporated and subsequently recovered. The light fluidizing oil is then largely separated from the solids. Those solids carrying residual light fluidizing oil are then brought into direct contact with steam, referred to herein as "blowing steam". The presence of the blowing steam reduces the boiling point of the water- immiscible light fluidizing oil to effect its more efficient removal from the solids. Effluent blowing steam and light oil vapor removed from the solids may be used to supply heat to the overall process. <IMAGE>

Water removal from glass objects leaving no stains - using row of tanks contg. organic solvent immiscible with water

Water is removed from the surface of an object, esp. glass, by immersion in a boiling dewatering bath (1) of solvent immiscible with water and contg. surfactants. The glass is then rinsed in pure organic solvent baths (2) to remove surfactants. The vapour is condensed and recycled. The water layer formed in bath (1) is removed, the water sepd. out and the solvent returned to bath (1). The novelty is the separate condensn. of the vapours from baths (1,2) and only condensate obtd. from bath (1) is returned to bath (1) via a water separator; only the condensate from bath (2) is returned to this bath via a drier. Three rinsing baths are pref. used, the first and third contg. boiling solvent, the middle bath contg. cold solvent and an ultrasonic vibrator. Used e.g. to dry optical glass.
