    Abstract: Lubricating oils of high-viscosity index are produced in good yield by a sequence involving mild hydrogenation, solvent refining and dewaxing. The process is particularly effective for the treatment of lube oil fractions containing at least 1 percent Conradson Carbon Residue using N-methyl pyrrolidone as the solvent.

    Abstract: A METHOD AND APPARATUS FOR CONTINUOUSLY MONITORING A COMPONENT OF A FLUID MIXTURE, SUCH AS THE NAPHTHENE CONTENT OF A HYDROCARBON MIXTURE. THE APPARATUS INCLUDES AN ADIABATIC SELECTIVE MICRO-REACTOR, SUCH AS A DEHYDROGENATION MICRO-REACTOR, IN WHICH THE FLUID MIXTURE IS REACTED TO ALTER A COMPONENT BY CONVERSION TO ANOTHER CHEMICAL COMPONENT HAVING DIFFERENT PHYSICAL PROPERTIES SUCH AS THE HEAT OF FORMATION THEREOF, AND MEANS FOR SENSING THE ALTERED PHYSICAL PROPERTY SUCH AS THERMOCOUPLES, THEREBY ENABLING DETECTION OF THE FLUID COMPONENT OF INTEREST IN ACCORDANCE WITH THE ALTERED PHYSICAL PROPERTY. IN A FURTHER EMBODIMENT A UNIQUE COMPUTER IS PROVIDED FOR CALCULATING THE CONCENTRATION IN THE MIXTURE OF THE FLUID COMPONENT OF INTEREST IN RESPONSE TO THE SENSED HEAT OF THE REACTION. THE METHOD OF THE INVENTION INCLUDES REACTING THE FLUID MIXTURE TO ALTER AT LEAST ONE COMPONENT OF THE FLUID MIXTURE TO A DIFFERENT CHEMICAL COMPONENT HAVING A DIFFERENT PHYSICAL PROPERTY THEREBY RENDERING THE ALTERED FLUID COMPONENT DISTINGUISHABLE, AND DETECTING THE FLUID COMPONENT OF INTEREST. IN ONE ASPECT OF THE METHOD THE DETECTING STEP INCLUDES THE STEPS OF SENSING THE HEAT OF THE REACTION BY SENSING THE FLUID TEMPERATURE BEFORE AND AFTER THE REACTION, AND GENERATING SIGNALS CORRESPONDING TO THE SENSED TEMPERATURES, AND IN RESPONSE TO THESE SIGNALS GENERATING A FURTHER SIGNAL CORRESPONDING TO THE CONCENTRATION IN THE MIXTURE OF THE FLUID COMPONENT OF INTEREST IN ACCORDANCE WITH A PREDETERMINED RELATIONSHIP BETWEEN THE HEAT OF SAID REACTION AND SAID CONCENTRATION.

    CPC classification number: C10G73/06

    Abstract: THIS INVENTION RELATES TO A METHOD OF SEPARTING WAS FROM A WAX BEARING MINERAL OIL EMPLOYING A MIXTURE OF AN AROMATIC HYDROCARBON AND A KETONE AS A DEWAXING SOLVENT AND CHILLING OF THE OIL-SOLVENT MIXTURE BY DIRECT HEAT EXCHANGE WITH A LIQUID REFRIGERANT. COOLING TO DEWAXING TEMPERATURE IS EFFECTED BY ADMIXING LIQUID REFIGERANT WITH THE OIL-SOLVENT MIXTURE AT AN ELEVATED PRESSURE AND REDUCING THE PRESSURE EFFECTING EVAPORATION OF REFRIGERANT AND CONCOMITANT COOLING. WAX CRYSTALS FORMED AT THE DEWAXING TEMPERATURE ARE SEPARATED FROM OIL-SOVENT MIXTURE AND REPULPED WITH ADDITIONAL FSOLVENT AND DEWAXED OIL PRODUCT IS SEPARTED FROM THE OIL-SOLVENT MIXTURE. REPULPED WAX IS SEPARATED FROM THE REPULPING SOLVENT MIXTURE FORMING WAX OF LOW OIL CONTENT. REPULPING SOLVENT CONTAINING OIL WASHED FROM THE WAX CRYSTALS IS RECYCLED TO THE INITAL DEWAXING STEP TO ACHIEVE HIGH YIELDS OF DEWAXED OIL.
