20090065432 | METHOD AND APPARATUS FOR REMOVING METAL SULPHIDE PARTICLES FROM A LIQUID STREAM - The invention provides a method for removal of metal sulphide particles from a liquid stream comprising a solvent and metal sulphide particles, using a filter system comprising at least one membrane, the method comprising contacting the liquid stream with the membrane, thereby transferring metal sulphide particles from the liquid stream onto the membrane surface to obtain a liquid stream depleted of metal sulphide particles and a filter system comprising a membrane enriched in metal sulphide particles. The invention further provides an apparatus for removal of metal sulphide particles from a liquid stream comprising a solvent and metal sulphide particles, wherein the apparatus comprises a solvent regenerator column ( | 03-12-2009 |
20100105959 | PROCESS FOR THE REMOVING POLY(PROPYLENE OXIDE) FROM PROPYLENE OXIDE BY MEMBRANE SEPARATION - The invention relates to a process for removing poly(propylene oxide) from propylene oxide by membrane separation, wherein a membrane having an average pore size of from 0 to 5 nm is used. In said process, a liquid feed comprising propylene oxide and poly(propylene oxide) may be separated by the membrane into a permeate comprising propylene oxide and either no poly(propylene oxide) or poly(propylene oxide) at a concentration which is lower than the poly(propylene oxide) concentration in the feed, and a retentate comprising propylene oxide and poly(propylene oxide) at a concentration which is higher than the poly(propylene oxide) concentration in the feed. | 04-29-2010 |
20100147745 | METHOD FOR REDUCING THE MERCURY CONTENT OF NATURAL GAS CONDENSATE AND NATURAL GAS PROCESSING PLANT - A method for reducing the mercury content of natural gas condensate, comprising the steps of providing a nanofiltration membrane having a feed side and a permeate side; contacting the natural gas condensate with the feed side of the membrane; and obtaining a mercury-depleted natural gas condensate at the permeate side of the membrane; and a natural gas processing plant comprising a condensate workup section including a nanofiltration membrane separation unit for reducing the mercury content of natural gas condensate. | 06-17-2010 |
20110247964 | PROCESS FOR REMOVING ASPHALTENIC PARTICLES - Process for removing asphaltenic particles from a hydrocarbon feed containing asphaltenic particles by treating the feed in a filter unit comprising a perforated tube surrounded by hollow longitudinal projections comprising a filter having openings of at most 50 micrometer diameter in which the internal space of each of the hollow projections is in fluid communication with the inside of the perforated tube and which filter is regularly subjected to cleaning by treating each of the projections with cleaning fluid wherein the flow of cleaning fluid is opposite to the direction of normal flow. | 10-13-2011 |
20120329138 | PROCESS FOR SEPARATION OF A MIXTURE CONTAINING A MICROBIAL SUBSTANCE AND A LIQUID - A process for separation of a mixture containing a microbial substance and a liquid using deformable filter is provided. | 12-27-2012 |
20130153511 | PROCESS FOR DEWATERING OF OIL SAND TAILING MUDS - The present invention relates to a process for dewatering oil sand tailing muds, comprising: (a) adding a flocculant into oil sand tailing muds and mixing the flocculant and the tailing muds; (b) filtering the flocculated tailing muds using a dynamic filtration system, wherein in step (b) a pressure difference is applied over the filter and wherein the dynamic filtration system comprises a means for producing a dynamic action by which the filter cake is continuously or intermittently moved, deformed and/or broken, the filter cake being the solidified material that sets on the filter during filtration. The process is useful for dewatering oil sand tailing muds from tailing ponds, such as those produced in the Athabasca Oil Fields in Canada. | 06-20-2013 |
20130337550 | PROCESS FOR THE EXTRACTION OF LIPIDS - The present invention provides a process for the extraction of lipids from microbial lipid-containing feedstock, comprising the steps of (a) subjecting the microbial lipid-containing feedstock to a treatment to release the lipids thereby producing a mixture; (b) subjecting the mixture obtained in (a) to a filtration in the presence of a first extraction solvent on a filter, wherein organic matter soluble in an extraction solvent and an aqueous mixture are removed as filtrate from a retentate comprising non-soluble matter; (c) separating the filtrate obtained from the filter into an organic and aqueous phase; and (d) subjecting the organic phase to a distillation treatment to separate solvent and an organic residue comprising extracted lipids. | 12-19-2013 |
20130338384 | PROCESS FOR THE RELEASE OF LIPIDS FROM MICROALGAE - The present invention provides a process for the release of lipids from lipid-containing microalgae feedstock, comprising heating the lipid-containing microalgae feedstock to a temperature of more than 80 to 120° C. and at a pressure of from 1 to 5 bar (absolute). | 12-19-2013 |
