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... Agent:

  
01/08/2015 > 1 patent applications in 1 patent subcategories.

20150008116 - Process and plant for distillation of methanol with heat recuperation: Process and plant for refining crude methanol, comprising at least three distillation stages operating in cascade at decreasing pressures, wherein a first stage (200) operates at a maximum distillation pressure (p2), a second stage (300) operates at a medium distillation pressure (p3), and a final distillation stage (400) operates at... Agent: Casale Sa

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

20150001062 - Method for separating a cooling lubricant agent from a bearing lubricant: The present invention relates to a method for reconditioning bearing lubricants that can be used in equipment for metal working, in which cooling lubricant that can be used in equipment for metal working is separated from the bearing lubricant. In addition the invention relates to a bearing lubricant for use... Agent:
