Title: Removal of metals and sulphur from petroleum
IPC: C10L9/02
Filed: 1971-04-22
Abstract: Purification of metal-contaminated petroleum coke of high sulphur content to form metallurgical grade coke is effected by (1) preoxidising the coke at 650-850 degrees F to substantially increase its surface area (2) contacting the coke with synthesis gas at 275-430 degrees F to convert the contaminating metals into gaseous carbonyls, (3) separating the metal carbonyls from the effluent synthesis gas, and (4) hydrodesulphurising the coke in the presence of synthesis gas at >1300 degrees F. The carbonylation of the metal impurities e.g. Ni, Fe and V is pref. effected at 450-750 psig, the sulphur present in the coke serving to accelerate the reaction. The metal carbonyls may subsequently be thermally decomposed to provide high grade metals. The synthesis gas for the hydrodesulphurisation is pref. simultaneously generated in that step by gasifying a part of the coke with oxygen and steam.

Abstract: Apple cider in the form of a clear gasified liquid having a specific gravity from about 1.000 to about 1.020 and an alcohol content from 2% to 12% by volume.  The cider has a delicate taste and lacks the bitter aftertaste often associated with apple ciders.  A process of making the cider as follows. Fresh juice from at least one cultivar of apples in which the juice has a specific gravity within the range from about 1.035 to about 1.065 and an organic nitrogen content within the range from about 0.01 to 0.05 is pasteurized.  One or more variety of sharp or sweet apples or a mixture of both may be employed. The pasteurized juice is inoculated with a species of wine yeast Saccharomyces cerevisieae var.ellipsoideus.  The inoculated juice is maintained in a pressure vessel at normal temperature for a time to initiate fermentation and to cause pressure to build up. The fermenting juice is then cooled to within the range from about 5.degree.C. to about 10.degree.C.  Fermentation is caused to continue until a cider is formed having the specific gravity mentioned.

Abstract: ABSTRACT OF THE DISCLOSURE The invention is apparatus in which stack gases containing pollut-ant gases and particulate matter are passed through a defined substantially horizontal flow path into which at least one selected liquid reagent is intro-duced in a prescribed manner to contact intimately the stack gases therein. The liquid reagent scrubs the stack gases and thereby removes a substantial portion of the pollutant gases and particulate matter therefrom.  In contrast to vertical tower scrubbers, one reagent may be used or several different re-agents may be employed at different stages of the horizontal flow path to effect best removal of various different pollutants contained within the stack gases.  Removal of sulfur dioxide may be accomplished by a highly re-active and substantially non-abrasive reagent, such as a lime solution and such solution further effects removal of materials in trace amounts in the stack gases such as mercury, beryllium and vanadium.  Removal of nitric oxide and other materials in trace amounts may also be accomplished by a process which includes as a reagent an oxidant.

Abstract: FORCE SENSING CONTROL APPARATUS AND  METHOD FOR ELECTRIC ARC FURNACE                 Abstract of the Disclosure A force sensing control apparatus and method is disclosed for detecting forces which resist movement of a motor driven electrode system in an electric arc furnace.          Force sensing circuitry monitors forces applied to an electrode system as it is positioned with respect to the furnace and force responsive controls inhibit electrode movement, hence preventing damage to the electrode or to its support structure, in response to predetermined changes in sensed reaction forces during positioning of the electrode.  Compensating circuitry continuously compensates for changes in forces arising from electrode weight variations and position changes of the elec-trode support structure so that the sensitivity of the control apparatus to applied forces which can damage electrode system remains consistently high.
