20090000939 | Membrane Distillation Process and Membrane Distillation Device - In a membrane distillation process in which a liquid to be concentrated is separated from a vapour space ( | 01-01-2009 |
20120038069 | MODULAR FLOW SYSTEM - The invention relates to a modular flow system comprising a plurality of frame elements which can be combined by means of welded web structures to various stacks comprising in each case at least two, in particular at least ten frame elements, in order to form different functional units such as in particular a membrane distillation stage, a steam generator, a condenser, a heat exchanger, a filter and/or a pervaporation stage. The frame elements according to the invention comprise in each case an outer frame provided with passage openings and vapour and/or fluid channels as well as a central inner region surrounded by the outer frame. Moreover, each frame element is provided on both sides with a welded web structure that delimits, on the one hand, the region comprising the passage openings and the central inner region and, on the other hand, at least two regions, each comprising a vapour and/or fluid channel. | 02-16-2012 |
20130264260 | FORWARD OSMOSIS SYSTEM COMPRISING SOLVENT SEPARATION BY MEANS OF MEMBRANE DISTILLATION - The invention relates to a system for separating a product contained as solvent in a solution to be processed, comprising at least one forward osmosis device ( | 10-10-2013 |
20130298590 | APPARATUS FOR DRYING AND/OR COOLING GAS - The invention relates to an apparatus ( | 11-14-2013 |
20130319923 | MULTISTAGE MEMBRANE DISTILLATION DEVICE - The invention relates to a multistage membrane distillation device comprising a heating stage ( | 12-05-2013 |
20140216916 | MEMBRANE DISTILLATION DEVICE - The invention relates to a membrane distillation device, comprising at least one condensation/evaporation stage, which comprises at least one condensation unit and at least one evaporation unit and to which vapor is fed and through which a liquid to be concentrated flows, wherein each condensation unit comprises a first vapor chamber that is bounded at least partially by a condensation wall and to which the fed vapor is supplied and each evaporation unit comprises a second vapor chamber that is bounded at least partially by a vapor-permeable, liquid-tight membrane wall, and in each condensation/evaporation stage at least one flow channel is provided, which is formed between such a condensation unit and such an evaporator unit adjacent to said condensation unit and which conducts the liquid to be concentrated, and thus the liquid to be concentrated is heated by means of the condensation wall, and vapor arising from the liquid to be concentrated enters the second vapor chamber through the membrane wall. At least one condensation/evaporation stage is expanded by an integrated apparatus for preheating the liquid to be concentrated, which apparatus comprises at least one additional vapor chamber, to which the vapor fed to the condensation/evaporation stage is supplied and in which the vapor is condensed, whereby the liquid to be concentrated is preheated. | 08-07-2014 |
20140290306 | ABSORPTION REFRIGERATION MACHINE - The invention relates to an absorption refrigeration machine ( | 10-02-2014 |
20140318945 | DISTILLATION STATION - A distillation station for separating components of a liquid mixture, comprising a vertical distillation column split into individual separation stages by fittings and which is further split by the liquid mixture feed into a stripping chamber and an enriching chamber, wherein in the stripping chamber the lower boiling fraction of vapour from the fluid mixture rising from a column sump comprising an evaporator is stripped, and in the enriching chamber the vapour is enriched with the lower-boiling fraction, which is withdrawn from a return fluid produced due to the vapour drawn from the column head being precipitated at least partially in a condenser and returned to the rectifier column, and the return liquid and the liquid mixture preferably fed between two separating stages being routed to the fittings vertically connected in sequence. In the process, each of the fittings comprise at least one liquid channel, which is separated at least partially from the vapour chamber of the distillation column by a two-sided vapour-permeable, liquid-tight membrane wall. | 10-30-2014 |
20150014144 | COOLING DEVICE - A cooling device for cooling a fluid comprises a vertical cooling tower, into an upper area of which the fluid to be cooled is fed and from a lower area of which the cooled fluid is discharged. The fluid in the cooling tower is cooled by a cooling gas flowing from the bottom to the top. At least one installation in which the fluid is conducted is provided in the gas space of the cooling tower through which cooling gas flows. Each installation comprises at least one fluid channel that is separated at least in part from the gas space of the cooling tower by a fluid-tight membrane wall that is permeable to vapour on both sides. | 01-15-2015 |
