20090277327 | High Permeability Membrane Operated at Elevated Temperature for Upgrading Natural Gas - The present invention discloses a new process of treating natural gas using high gas permeability polybenzoxazole polymer membranes operated at high temperatures that can provide sufficient dew point margin for the product gas. The high gas permeability polybenzoxazole polymer membranes can be used for a single stage membrane system or for the first stage membrane in a two stage membrane system for natural gas upgrading. Simulation study has demonstrated that a costly membrane pretreatment system such as a MemGuard™ system will not be required in the present new process. The new process can achieve significant capital cost saving and reduce the existing membrane footprint greater than 50%. | 2009-11-12 |
20090277328 | Efficient gas-separation process to upgrade dilute methane stream for use as fuel - A membrane-based gas separation process for treating gas streams that contain methane in low concentrations. The invention involves flowing the stream to be treated across the feed side of a membrane and flowing a sweep gas stream, usually air, across the permeate side. Carbon dioxide permeates the membrane preferentially and is picked up in the sweep air stream on the permeate side; oxygen permeates in the other direction and is picked up in the methane-containing stream. The resulting residue stream is enriched in methane as well as oxygen and has an EMC value enabling it to be either flared or combusted by mixing with ordinary air. | 2009-11-12 |
20090277329 | METHOD FOR THE REMOVAL OF SMUT, FINE DUST AND EXHAUST GAS PARTICLES, PARTICLE CATCH ARRANGEMENT FOR USE IN THIS METHOD, AND USE OF THE PARTICLE CATCH ARRANGEMENT TO GENERATE A STATIC ELECTRIC FIELD - This inventions provides a method for the removal of smut, fine dust and exhaust gas particles from polluted air comprising providing a particle catch arrangement with a charged surface, the particle catch arrangement being arranged to generate a static electric field, wherein the electric field is at least 0.2 kV/m. The invention further provides a particle catch arrangement comprising a surface that can be charged, further comprising a generator arranged to generate charge to the surface that can be charged and to generate a static electric field of at least 0.2 kV/m, wherein the particle catch arrangement is part of or integrated with an object comprising street furniture. | 2009-11-12 |
