20150034474 - Process for obtaining food grade hexane: The present invention relates to a process for obtaining food grade hexane, comprising: fractionating a hydrocarbon feed having a boiling point in the range of 50° C. to 140° C. to obtain a hydrocarbon fraction having boiling point in the range of 63° C. to 69° C. and having 3%-15%... Agent: Bharat Petroleum Corporation Ltd

01/29/2015 > 1 patent applications in 1 patent subcategories.

20150027873 - Iterative reactive distillation of dynamic ester mixtures: An iterative method of performing a reactive distillation of dynamic ester libraries containing n×m (m≦n) components, to reduce such mixtures to n pure ester species. The distillation occurs under anhydrous conditions, using metal alkoxide catalysts. Vacuum distillation of the mixture then isolates the most volatile ester at the expense of... Agent: University Of Houston System

01/22/2015 > 1 patent applications in 1 patent subcategories.

20150021160 - Processes for producing acetic acid: Processes for the reduction and/or removal of permanganate reducing compounds (PRC'S) formed by the carbonylation of methanol in the presence of a Group VIII metal carbonylation catalyst to produce acetic acid are disclosed. More specifically, processes for reducing and/or removing PRC's or their precursors from intermediate streams during the formation... Agent:

01/15/2015 > 6 patent applications in 5 patent subcategories.

20150014146 - Desalination system and desalination method: A desalination system includes a water tank, a water-repellent particle layer located at a lower portion of the tank and composed of water-repellent particles, and a devolatilizing layer located below the water-repellent particle layer. Liquid is introduced to the tank, the introduced liquid is heated to be evaporated into water... Agent:

20150014145 - Measurement system included in desalination system, desalination system, and desalination method: In a desalination system, a water-repellent particle layer is provided at a lower portion of a water tank and composed of water-repellent particles. A devolatilizing layer is provided below the layer. Liquid is provided in the tank and is heated for evaporation, and obtained vapor passes through the particle layer... Agent: Panasonic Corporation

20150014147 - System and method of desalinating seawater: Saline water from a body of water is desalinated using a water purification system. Chambers of a plurality of tanks are filled with a volume of saline water. The saline water is heated to increase a pressure and produce water vapor within the chamber of each tank. A condensation valve... Agent:

20150014148 - Process for energy recovery in manufacturing cellulose esters: Integration of an acid recovery system in the manufacturing of cellulose esters may include heat recovery from a carboxylic acid recovery distillation column by solvent extracting a weak acid stream to form a first overhead stream and a first bottoms stream; distilling the first overhead stream in a distillation column... Agent:

20150014149 - Controlled-gradient, accelerated vapor-recompression apparatus and method: An accelerated vapor recompression apparatus 10 converts incoming flow 35a to a concentrate 35c by developing a concentration profile 146 within a tank 30 holding a liquid 23 containing dissolved solids. The resulting curve 160 of saturation temperature of the stratified liquid 23 (such as a brine 23 or other... Agent:

20150014150 - Process for energy recovery in purifying carboxylic anhydride for manufacturing cellulose esters: Integration of a carboxylic anhydride purification system in the manufacturing of cellulose esters may include processes that includes distilling the crude carboxylic anhydride stream (that includes a carboxylic anhydride and a carboxylic acid) in a distillation column having an overhead or side stream comprising purified, vaporous carboxylic anhydride and a...
