554204000 | Carboxylic acid, anhydride, or acid halide treating agent | 6 |
20120203017 | Method for Purifying Fatty Acid Alkyl Ester Greatly Loaded with Saponification Products - A method for the continuous extraction of impurities, in particular saponification products, from a fatty acid alkyl ester phase produced by transesterification of vegetable or animal oils or fats with a great tendency to form saponification products, by means of an aqueous, acid glycerol phase containing a complexing agent. | 08-09-2012 |
20120245370 | CHEMICAL ADDITIVES AND USE THEREOF IN STILLAGE PROCESSING OPERATIONS - A method is provided for the use of a chemical additive to improve the separation of oil from the process stream (whole stillage, thin stillage or syrup) generated as a byproduct in corn to ethanol production. | 09-27-2012 |
20120245371 | PROCESS FOR THE PURIFICATION OF CRUDE ALKALINE GLYCEROL - The present invention generally concerns a treatment process for crude alkaline glycerol obtained as a by-product of transesterification reaction of natural oils and fats with lower alcohols. The present invention particularly concerns the treatment of crude alkaline glycerol obtained as a by-product of the biodiesel production from vegetable oils and animal fats using organic alkyl carboxylic acids or their aqueous solution, comprising the steps of: (a) acidification of the crude alkaline glycerol stock to pH in the range of about 4 to about 6, particularly 4 to 5, with organic alkyl carboxylic acids, in the presence of water in the range from about 5% to about 50%, particularly 15 to 30%, in weight with respect to the weight of the crude alkaline glycerol stock; (b) separating the formed free fatty acids, for instance by flotation; (c) removing the alcohol present in the acidified crude glycerol stock, for instance by distillation; (d) separating the acidic glycerol. | 09-27-2012 |
20130012734 | METHOD FOR PRODUCING REFINED A FAT OR OIL - A method for manufacturing a refined fat or oil, including: carrying out a first steam treatment of bringing a fat or oil into contact with water vapor; and subsequently carrying out a second steam treatment of bringing the fat or oil having a temperature lower by 10° C. or more than a temperature of the fat or oil in the first steam treatment into contact with water vapor in the presence of an organic acid. | 01-10-2013 |
20140171672 | Method for Recovering Lipids from a Microorganism - A method is for recovering lipids from algae, which comprises providing a biomass of a lipid-producing algae. The cell wall and/or cell membrane of said algae is ruptured by algal cytotoxin thereby releasing lipid from the cell, and recovering said lipid. An integrated system is for recovering lipids from lipid-producing algae cells. | 06-19-2014 |
20160002568 | METHODS FOR DEGUMMING OILS - Processes and systems are provided for effectively degumming vegetable oils with the use of an acid and base pretreated mixture of vegetable oil. The pretreated mixture is subjected to compression and one or more intervals of explosive decompression of the compressed mixture to form a degummed vegetable oil. Also provided are compression and decompression rates and conditions that can be used to effectively degum vegetable oil to achieve reduced levels of phosphorus and metals such as iron, calcium and magnesium. | 01-07-2016 |
