20110024342 | SEPARATION MEMBRANE MODULE - A separation membrane module is provided with a module main body | 02-03-2011 |
20110174722 | ZEOLITE SEPARATION MEMBRANE, METHOD FOR PRODUCING THE SAME, AND BONDING AGENT - A separation membrane according to the present invention is characterized by having a porous tube containing an alumina as a main component and an attachment member disposed in a connection position of the porous tube, wherein the porous tube and the attachment member are bonded by a ceramic oxide-based bonding agent containing 17 to 48 wt % of SiO | 07-21-2011 |
20120152840 | METHOD FOR DEWATERING WATER-CONTAINING ORGANIC SUBSTANCE - The present invention is to provide a VP dewatering method being applicable over a wide range, having good handling properties, and being economically efficient and highly energy-saving, which comprises compression-pressuring a dewatered vapor product to elevate a condensation temperature thereof and then re-using the same as a heat source for vaporizing a supply liquid. In dewatering a water-containing organic substance which is a liquid starting material according to a vapor permeation membrane separation method, a dewatered organic substance vapor discharged from a membrane module is pressurized with a compressor to elevate the condensation temperature of the vapor and then the vapor is fed to a vaporizer of said method to collect and use the latent heat of condensation thereof. | 06-21-2012 |
20120175290 | PERVAPORATION MEMBRANE SEPARATING MODULE - To reduce an influence of concentration polarization in a simple structure without an outer membrane element | 07-12-2012 |
20130240448 | METHOD FOR SEPARATING WATER BY SEPARATION MEMBRANE, SEPARATION MEMBRANE FOR DEHYDRATING AQUEOUS ORGANIC ACID SOLUTION AND METHOD FOR MANUFACTURING THE SAME - The method for separating water by a separation membrane is a method for separating water from an aqueous organic acid solution by the separation membrane, and the separation membrane consists of polycrystalline membrane of mordenite (the chemical composition of the frame: Al | 09-19-2013 |
20140144321 | CARBON DIOXIDE SEPARATION SYSTEM - In the carbon dioxide separation system, a mixed gas having a carbon dioxide concentration of 3 to 75% is introduced into a primary carbon dioxide separation device equipped with a zeolite membrane for carbon dioxide separation to produce a primary permeated gas having a carbon dioxide concentration of 80% or more on the permeate side of the zeolite membrane and also reduce the carbon dioxide concentration of a primary gas on the non-permeate side of the zeolite membrane to 3 to 15%. Next, the primary gas on the non-permeate side is introduced into a secondary carbon dioxide separation device that employs an amine absorption method or a pressure swing adsorption (PSA) method to produce a secondary separated gas having a carbon dioxide concentration of 80% or more separated by the separation device and also produce a carbon-dioxide-removed gas having a carbon dioxide concentration of 2% or less. | 05-29-2014 |
20140201985 | DEVICE FOR MOUNTING A SEPARATION MEMBRANE ELEMENT IN A SEPARATION MEMBRANE MODULE - In the device for mounting a separation membrane element in a separation membrane module, a sealing member is constituted of a plurality of notched circular packings made of graphite, for example, each having a notched circular shape as viewed in a plan view. The plurality of notched circular packings are fitted on an upper end portion of the separation membrane element in a state where the notched circular packings are made to overlap with each other in plural stages, notched portions of the notched circular packings arranged adjacent to each other vertically are arranged at positions different from each other as viewed in a plan view, the notched circular packings in plural stages are received by the inwardly projecting annular receiving portion in the mounting hole, the notched circular packings in plural stages are pressed to the annular receiving portion by threaded engagement of the press fitting thus applying sealing. | 07-24-2014 |
