Abstract: A liquid atomization process comprises forming a two-phase fluid mixture of a liquid and a gas, under pressure, dividing the fluid into two separate streams which are passed into and through an impingement mixing zone in which they are impingement mixed to form a single stream of two-phase fluid. The mixed, single stream is then passed into and through a shear mixing zone and then into a lower pressure expansion zone, in which atomization occurs to form a spray of atomized drops of the liquid. The impingement and shear mixing zones comprise respective upstream and downstream portions of a single cavity in a nozzle. This is useful for atomizing the hot feed oil in an FCC process.

Abstract: A gas distribution grid for a slurry reactor includes a plurality of gas injectors horizontally arrayed across, and extending through, an otherwise gas and liquid impervious plate. The injectors have a throat open at both ends, with a gas pressure reducing bore at one end which is the entrance end and with the other end opening into an upward opening cone. Flow diverting means in the injectors prevents slurry solids from entering the throat and being attrited by the high velocity gas jet exiting the bore into the throat. It is preferred that the gas injectors not protrude above the top surface of the grid and flat space is eliminated by means such as angular fillers, to prevent solids accumulation top of the grid. A chamfer may be present at the junction of the bore and throat to prevent unrestricted expansion of the gas jet entering the throat. This is useful for injecting gas into a reactive hydrocarbon synthesis slurry in a slurry reactor, with reduced catalyst attrition and deactivation.

Abstract: A three stage process for producing high quality white oils, particularly food grade mineral oils from mineral oil distillates. The first reaction stage preferably employs a sulfur resistant hydrotreating catalyst and produces a product suitable for use as a high quality lubricating oil base stock. The second reaction stage preferably employs a hydrogenation/hydrodesulfurization catalyst combined with a sulfur sorbent and produces a product stream which is low in aromatics and which has substantially “nil” sulfur. The final reaction stage employs a selective hydrogenation catalyst that produces a product suitable as a food grade white oil.

Abstract: A high VI and low pour point lubricant base stock is made by hydroisomerizing a high purity, waxy, paraffinic Fischer-Tropsch synthesized hydrocarbon fraction having an initial boiling point in the range of 650-750° F., followed by catalytically dewaxing the hydroisomerate using a dewaxing catalyst comprising a catalytic platinum component and an H-mordenite component. The hydrocarbon fraction is preferably synthesized by a slurry Fischer-Tropsch using a catalyst containing a catalytic cobalt component. This combination of the process, high purity, waxy paraffinic feed and the Pt/H-mordenite dewaxing catalyst, produce a relatively high yield of premium lubricant base stock.

Abstract: A cavitation enhanced atomizing process comprises forming a flowing solution of the liquid to be atomized and a lower boiling cavitating liquid. This flowing solution is then contacted with a pressure reducing means, at a temperature below the bubble point of the cavitating liquid in the solution, to produce cavitation bubbles. These bubbles comprise cavitation liquid vapor and the bubble nucleation produces a two-phase fluid of the bubbles and liquid solution. The two-phase fluid is passed downstream into and through an atomizing means, such as an orifice, and into a lower pressure atomizing zone, in which the bubbles vaporize to form a spray of liquid droplets. The nucleated bubbles also grow in size as the so-formed two-phase fluid passes downstream to and through the atomizing means.

Abstract: The present invention is a slurry-type process for upgrading heavy oils to FCC and S/C feeds under temperature and pressure conditions similar to MSHP, but employing catalysts in concentrations small enough (e.g., <300 ppm Mo on feed) that they need not be recycled.

Abstract: Sour natural gas is processed to remove the sulfur compounds and recover C4+/C5+ hydrocarbons by scrubbing the gas with an amine solution to remove most of the sulfur, followed cooling the gas to remove C4+/C5+ hydrocarbons and more sulfur compounds as liquid condensate to produce a gas having less than 20 vppm of total sulfur. The condensate is sent to a fractionator to recover the C4+C5+ hydrocarbons. The sulfur and hydrocarbon reduced gas is contacted first with zinc oxide and then nickel, to produce a gas having less than 10 vppb of total sulfur which is passed into a synthesis gas generating unit to form a very low sulfur synthesis gas comprising a mixture of H2 and CO. This synthesis gas is useful for hydrocarbon synthesis with increased life of the hydrocarbon synthesis catalyst and greater hydrocarbon production from the hydrocarbon synthesis reactor. Contacting the synthesis gas with zinc oxide further reduces the sulfur content to below 3 vppb.

Abstract: This invention relates to a process of recycling condensate from a hydrocarbon or alcohol synthesis, wherein the condensate comprises water and contaminants such as lower molecular weight hydrocarbons, alcohols, and other oxygenates. A hot gaseous mixture comprising CH4 and steam contacts the condensate so as to strip the contaminants from the condensate. The stripped contaminants, CH4, and steam are separately recovered as a gaseous stream from the remaining purified water. The recovered CH4-containing gaseous stream may be used in synthesis gas (CO/H2) generation processes with the generated synthesis gas then being used in a hydrocarbon synthesis process to produce heavy hydrocarbons.
