Distillation: processes, separatory inventions 07/09

20090183981 - Integrated pyrolysis gasoline treatment process: An integrated process for treating pyrolysis gasolines, including: feeding the pyrolysis gasoline to a first stage wherein the pyrolysis gasoline is substantially depentanized and acetylene and diolefins are reacted with hydrogen to produce an effluent having a reduced acetylene and diolefin content; and feeding the effluent to a second stage,... Agent: Osha Liang LLP / Cdtech

20090173617 - Desalinization by evaporation from capillary material: A method and an apparatus for desalinizing raw water are disclosed. The method can include wicking the raw water into a porous material by capillary action and heating the raw water in the porous material with a heating element to form water vapor. The water vapor then can be condensed... Agent: Klarquist Sparkman, LLP

20090173618 - Method of an apparatus for generating a vacuum and for separating volatile compounds in polycondensation reactions: The invention relates to a method for generating a vacuum and for separating volatile compounds during esterification, transesterification and/or polycondensation reactions. One or several jets of steam comprising a spray condenser, which is arranged up or downstream, are connected to the suction side of a reactor which is to be... Agent: K.f. Ross P.C.

20090166171 - Trifunctional membrane tube arrays: Membrane tubes or similar membrane devices are arrayed in layers so that liquid placed on their outer surfaces may be evaporated and also drain onto lower membrane devices. The entire array is subjected to moving air to enhance evaporation. The membrane devices function as filters while permeating water from industrial... Agent: William L. Krayer

20090166172 - Ethanol plant process: The present invention conserves water by reducing the heat load placed on a cooling tower during the ethanol fuel production process. An air cooler is placed between the ethanol vapor condenser and the cooling tower thereby minimizing process temperature spikes before water enters the cooling tower. This, in turn, shortens... Agent: Cornelius P. Dukelow Abington Intellectual Property Law Group, PC

20090166173 - Effluent gas recovery process for silicon production: Purified SiHCl3 is used as a sweep gas across a permeate side of a gas separation membrane receiving effluent gas from a polysilicon reactor. The combined sweep gas and permeate is recycled to the reactor.... Agent: Air Liquide Intellectual Property

20090166174 - Azeotropic distillation method: An azeotropic distillation method, comprising a reaction step, a distillation step for separating and refining a reaction product, and a recovery step for collecting a reactant after the distillation step; wherein at least one component constituting the reactant in the reaction step can act as an entrainer for the azeotropic... Agent: Sughrue Mion, PLLC

20090166175 - Solvent extraction and recovery: Systems and methods for improving dense gas solvent extraction of a solute and recovery of the solvent are provided. A pressure of the solvent/solute mixture obtained from an extraction chamber is increased, e.g. with a pump, thereby providing the mixture above saturation conditions. The increased pressure provides greater solubility of... Agent: Townsend And Townsend And Crew, LLP

20090166176 - Method for purifying polymerizable compounds: Process for distillatively purifying polymerizable compounds using a high-boiling, inert, thermally long-term-stable substance as a boiling oil, characterized in that the boiling oil is disposed in the bottom of a rectification column....
