Abstract:
The present invention relates to a method for treating waste petroleum, and more specifically relates to providing a method for treating various waste petroleum (such as a lubricating oil, a re¬ frigeration oil, an insulating oil and the like used in general machinery and equipment as well as in particular radioactive waste petroleum) into eco-friendly solid that leaching of oil would not occur. That is, the method of the present invention comprises mixing 85-90% by weight of waste petroleum and 10-15% by weight of a mixed solution in which a concentrated sulfuric acid is mixed with a concentrated nitric acid at a mixing ratio of 1:2; producing precipitates and filtrates (3H+3, SO4 2, and NO3" ) and modified waste oil obtained by the mixing step (a); adding 85-90% by weight of the mixed solution in which the precipitates and the filtrates are mixed homo¬ geneously to 10-15% by weight of a saturated aqueous sodium hydroxide solution (Na+OH +H+2 O 2), thereby carrying out a second polymerization reaction to produce solid particles; col- loidizing a mixture obtained by uniformly stirring the solid particles; adding 10-15% by weight of a diisocyanate compound to 85-90% by weight of the colloidized mixture before reactor cooling of the colloidized mixture, thereby carrying out a third polymerization reaction serially to obtain a mixture in the form of powder with a gas; purifying the gas generated in the third polymerization reaction and discharging the purified gas into the atmosphere by way of a complex salt reaction; and filling the compound into a resin as a filling material and compression molding and reclaiming the filled compound. As described above, the method of the present invention can treat radioactive waste petroleum used in a nuclear power station as well as various waste petroleum, thereby stabilizing waste petroleum chemically and physically, wherein the method comprises mixing waste petroleum with a concentrated sulfuric acid and a concentrated nitric acid; adding sodium hydroxide, thereby carrying out a second polymerization reaction to produce solid particles; colloidizing a mixture obtained by uniformly stirring the solid particles; adding a diisocyanate compound in reactor, thereby carrying out a third polymerization reaction to obtain a new compound in the form of powder; discharging a generated gas into the atmosphere; and filling the compound into a resin as a filling material and compression molding and reclaiming the filled compound. Further, a new compound produced by treating waste petroleum according to the present invention, can be compression-molded as block with various resins and be reclaimed readily. Also, there are no problems caused by leaching of oil. Accordingly, the present invention is excellent invention that can prevent industrial pollutions caused by waste petroleum, specifically waste petroleum used in a nuclear power station.
Abstract:
A method for upgrading the viscoelastic properties of a heavy oil by altering its elastic modulus. An effective amount of one or more elastic modulus lowering agents are used, wherein preferred elastic modulus lowering agents include mineral and organic acids and bases, preferably strong bases, such as hydroxides of metals selected from the alkali and alkaline-earth metals.

The present invention relates to a method for removal and recovery of an organic amine from a hydrocarbon stream containing the amine, comprising the steps of: i) mixing the hydrocarbon stream containing the amine with an aqueous inorganic acid in a volumetric ratio of hydrocarbon stream: aqueous inorganic acid of >1:1-5:1, preferably 1.5:1-4:1, more preferably 3:1, ii) phase separating of hydrocarbon and aqueous phase; hi) removing the hydrocarbon phase and optionally further purifying thereof, iv) optionally recycling at least a part of the hydrocarbon phase obtained in step (iii) into mixing step (i), v) mixing the aqueous phase obtained in step (iii) with an aqueous alkaline solution, vi) phase separating of an aqueous phase and an organic phase formed, vii) removing the organic phase obtained in step (vi) and optionally further purifying thereof.
Abstract:
Methods and system for obtaining long chain carbons that generally include forming a conversion mixture of an alcohol and a base, adding the conversion mixture to oil ( such as petroleum based oil, crude oil, used oil, used motor oil, and new motor oil) to form a reaction mixture, adding a high nitrate compound the reaction mixture, and separating out the long chain carbons for use as an input by other processing such as pharmaceutical and/or additional petro-chemical processing. Additional cooling and/or filtering processes may be utilized to complete and/or optimize oil conversion.
Abstract:
High molecular weight naphthenic tetra-acids are added to a base crude oil to prevent and/or reduce fouling of crude oil refinery equipment. The method includes adding an effective amount of a high molecular weight naphthenic tetra-acid to the base crude oil to form a crude oil mixture and feeding the crude oil mixture to a crude oil refinery component. Particularly, the high molecular weight naphthenic tetra- acids include ARN acids.

Abstract:
A system and method for extracting complex, variable length computer instructions from a stream of complex instructions each subdivided into a variable number of instruction bytes, and aligning instruction bytes of individual ones of the complex instructions. The system receives a portion of the stream of complex instructions and extracts a first set of instruction bytes starting with the first instruction bytes, using an extract shifter. The set of instruction bytes are then passed to an align latch where they are aligned and output to a next instruction detector. The next instruction detector determines the end of the first instruction based on said set of instruction bytes. An extract shifter is used to extract and provide the next set of instruction bytes to an align shifter which aligns and outputs the next instruction. The process is then repeated for the remaining instruction bytes in the stream of complex instructions. The isolated complex instructions are decoded into nano-instructions which are processed by a RISC processor core.
