| 435281000 | Petroleum oil or shale oil treating | 6 |
| 20080286855 | THERMACETOGENIUM PHAEUM CONSORTIUM FOR THE PRODUCTION OF MATERIALS WITH ENHANCED HYDROGEN CONTENT - An isolated microbial consortium is described that includes a first microbial consortium having | 11-20-2008 |
| 20090111165 | EMULSIFICATION-FREE DEGUMMING OF OIL - This invention relates to an oil degumming method that is free of emulsification. This method includes the steps of treating crude oil first with immobilized phospholipase and then extracting the phospholipase-treated crude oil with pure water or an aqueous solution. | 04-30-2009 |
| 20120028341 | PETROLEUM BIOPROCESSING TO PREVENT REFINERY CORROSION - The present invention relates to the bioupgrading of crude oil is directed to a process for decreasing the acidity of an acidic crude oil, comprising contacting an acidic crude oil with a mixture nitrogen containing compounds selected from the group comprising ammonia, ammonia hydroxide, amines and the salts thereof, and in the presence of lipase enzyme, under conditions of suitable temperature and pressure sufficient to form the corresponding amide. The resulting naphthenic acid derived amides can then be processed normally in a refinery using such processes as cracking or hydrotreating and converted to hydrocarbon, ammonia and carbon dioxide without causing damage to the refinery infrastructure. This enzyme process is done at reduced temperatures (40-60° C.) and pressures requiring less energy. | 02-02-2012 |
| 20120034683 | PETROLEUM BIOCONVERSION OF ORGANIC ACIDS TO PREVENT REFINERY CORROSION - The present invention relates to the use of microorganisms (biocatalysts), or catalysts derived from these organisms (enzymes), to improve the quality of crude oil and bitumen as an attractive alternative to current upgrading methods. The invention identifies and characterizes the microorganism species, in particular, | 02-09-2012 |
| 20130095562 | OIL RELEASE WITH AMINO ACID-BASED COMPOUNDS HAVING A LONG CHAIN N-ACYL GROUP - Chemical compounds that are N-acyl amino acids or derivatives thereof having long chain N-acyl groups were found to have oil-releasing activity. Solutions containing these compounds may be introduced into oil reservoirs or onto oil-contaminated surface sites to release oil from oil-coated surfaces. The released oil may be recovered for further processing or waste disposal. | 04-18-2013 |
| 20150093808 | ENZYME-ASSISTED EFFLUENT REMEDIATION - This invention relates to methods to reduce the levels of contaminants in effluent produced in industrial operations, e.g., refinery operations. In particular, the invention relates to method to reduce the level of organic contaminants in industrial effluent wherein said effluent lacks sufficient dissolved oxygen to support enzymatically-catalyzed removal of organic contaminants comprising adding to the effluent one or more enzymes in an amount effective to reduce the level of organic contaminants in said effluent, wherein said enzymes require oxygen for enzymatic activity; and adding an in situ source of dissolved oxygen. | 04-02-2015 |
