Abstract: THIS PROCESS PERTAINS TO THE ABATEMENT OF POLLUTION FROM SULFIDE-BEARING WASTE WATERS. WASTE AQUEOUS SOLUTIONS E.G., SOUR WATER, TREATED SOUR WATER, AND OTHER REFINERY WASTE WATERS CONTAINING SULFIDES ARE ADMIXED WITH A HYDROCARBONACEOUS FUEL AND REACTED BY PARTIAL OXIDATION WITH AN OXYGEN-RICH GAS IN A FREE-FLOW NONCATALYTIC GAS GENERATOR AT AN AUTOGENOUS TEMPERATURE IN THE RANGE OF ABOUT 1500 TO 3500*F. AND A PRESSURE IN THE RANGE OF ABOUT 1 TO 250 ATMOSPHERAS TO PRODUCE SYNTHESIS GAS FROM WHICH HYDROGEN SULFIDE MAY BE SUBSEQUENTLY RECOVERED AND CONVERTED INTO BY-PRODUCT SULFUR.

Abstract: IN A HIGH PRESSURE SYSTHESIS GAS GENERATING PROCESS CONTINUOUS CONTROL OF THE PH IN THE SYSTEM MAY BE ACCOMPLISHED BY SUPPLEMENTING THE NITROGEN IN THE PRIMARY HYDROCARBON FUEL AND OXYGEN-ENRICHED GAS FED TO THE GENERATOR WITH A CONTROLLED AMOUNT OF NITROGEN IN THE FORM OF NITROGEN CONTAINING ORGANIC COMPOUNDS, AND CONTINUOUSLY NEUTRALIZING ALL OR A PORTION OF THE FORMIC ACID PRODUCED IN THE SYSTEM WITH AMMONIA SYNTHESIZED IN THE SYSTEM. CARBON-STEEL PROCESS EQUIPMENT AND PIPING IS THEREBY PROTECTED FROM CORROSION AND SYSTEM UPSETTING EMULSIONS ARE PREVENTED FROM FORMING IN THE CARBON RECOVERY ZONE.

Abstract: 1. IN A METHOD FOR RECOVERING CARBON FROM A CARBONWATER DISPERSION BY CONTACTING SAID DISPERSION WITH AN OIL BLEND TO FORM A CARBON OIL SLURRY, THE IMPROVEMENT CONSISTING OF USING AN OIL BLEND OF 4 TO 60 WEIGHT PERCENT OF ASPHALTIC RESIDUAL OIL BOILING ABOVE 100* F., SAID AMOUNT BEING SUFFICIENT TO SATISFY THE OIL ABSORTION NUMBER OF SAID CARBON AND THE REMAINDER OF SAID BLEND COMPRISING A LIGHT, LIQUID, NON-ASPHALTIC CONTAINING HYDROCARBON BOILING BELOW ABOUT 100*F. FROM THE GROUP OF KEROSENE, GAS OIL, DIESEL FUEL, SHALE FUEL OIL, DEASPHALTED OIL AND DECANTED OIL FROM A FUEL CATALYTIC CRACKING UNIT WHEREBY THE RESULTING CARBON-OIL SLURRY REMAINS PUMPABLE EVEN WHEN CONTAINING UP TO 20 WEIGHT PERCENT OF CARBON.

Abstract: Production of synthesis gas from a slurry of particulate solid carboniferous fuels, e.g., petroleum coke, coke from bituminous coal, coal, oil shale, tar sands, pitch, or mixtures of these materials in water or in a hydrocarbon liquid fuel. The amount of particulate solid carboniferous fuel in a pumpable slurry may be increased to 75 wt. percent and the particle size of the solid fuel may be increased to pass through a 12 mesh screen by the addition of 2 to 10 wt. percent of soot as produced, for example, by the partial oxidation of crude oil. The slurry at a relatively low velocity in the range of 5 to 50 feet per second is mixed with a stream of oxidizing gas at a relatively high velocity in the range of 200 feet per second to sonic velocity at the burner tip to form an atomized dispersion of water, hydrocarbon liquid fuel, oxidizing gas, and solid carboniferous fuel. Under synthesis gas generating conditions, the atomized dispersion is reacted to produce a gaseous mixture of hydrogen and carbon monoxide. By this process, pumpable slurry feeds of low cost solid carboniferous fuels may be gasified in a synthesis gas generator without being preheated.
Abstract translation: 从颗粒状固体含碳燃料（例如石油焦炭，来自烟煤的煤，煤，油页岩，焦油砂，沥青或这些材料在水中或烃液体燃料中的混合物）的浆料生产合成气。 可泵送浆料中的固体含量的固体含量的燃料的量可以增加到75wt。 可以增加固体燃料的颗粒尺寸以通过加入2至10重量％的通过12目筛网。 例如，通过原油的部分氧化产生的烟灰百分比。 以5至50英尺/秒的相对较低的速度将浆料与氧气气体流以200英尺/秒的相对较高的速度与燃烧器尖端处的声速混合，以形成雾化的分散体 的水，烃液体燃料，氧化气体和固体含碳燃料。 在合成气体产生条件下，使雾化的分散体反应以产生氢气和一氧化碳的气体混合物。 通过该方法，低成本固体含碳燃料的可泵送浆料进料可以在合成气发生器中气化而不被预热。

Abstract: A CONTINUOUS PROCESS FOR THE LIQUID PHASE, NON-CATALYTIC, AIR OXIDATION OF SOUR WATER IN WHICH THE SULFUR COMPOUNDS IN THE WATER ARE CONVERTED TO NON-POLLUTING, NONOXYGEN DEMANDING COMPOUNDS INVOLVES HEATING THE WATER AND OXIDIZING THE HEATED WATER WITH COUNTERCURRENT OR CO-CURRENT FLOW OF THE WATER AND OXIDIZING MEDIUM. THE PROCESS RAPIDLY CONVERTS OBJECTIONABLE SULFIDES AND INTERMEDIATE SULFUR COMPOUNDS SUCH AS THIOSULFATES, TETRATHIONATES, POLYTHIONATES, SULFITES AND POLYSULFIDES TO SULFATE.

Abstract: IN A HIGH PRESSURE SYNTHESIS GAS GENERATING PROCESS, CONTINUOUS CONTROL OF THE PH IN THE SYSTEM MAY BE ACCOMPLISHED BY DETERMINIG THE NITROGEN IN THE PRIMARY HYDROCARBON FUEL AND OXYGEN-ENRICHED GAS FED TO THE GENERATOR, SUPPLEMENTING SAID NITROGEN WITH A CONTROLLED AMOUNT OF NITROGEN IN THE FORM OF NITROGEN CONTAINING COMPOUNDS, SYNTHESIZING AMMONIA IN THE SYSTEM, AND CONTINUOUSLY NEUTRALIZING ALL OR A PORTION OF THE FORMIC ACID PRODUCED IN THE SYSTEM WITH THE AMMONIA SYNTHESIZED IN THE SYSTEM AND WITH ADDITIONS OF SUPPLEMENTAL AMMONIA FROM AN EXTERNAL SOURCE. CARBON-STEEL PROCESS EQUIPMENT AND PIPING IS THEREBY PROTECTED FROM COROSION AND SYSTEM UPSETTING EMULSIONS ARE PREVENTED FROM FORMING IN THE CARBON RECOVERY ZONE.
