20080230467 | FILTER DEVICE - A filter device for mass exchange between two media separated by a membrane providing a low-stress transfer of blood flow from the connection area of the filter device to the fibers of a hollow fiber bundle is disclosed. Relatively uniform utilization of the fibers is provided by a membrane in the form of a hollow fiber bundle whose fiber cavities form a first flow space, with at least one inflow or outflow chamber connected to the first flow space being provided for supplying a medium to the hollow fiber bundle or removing a medium from the hollow fiber bundle. The inflow or outflow chamber is adjacent to an essentially circular or semicircular channel which is designed to be open in the direction of the ends of the hollow fibers and is connected to an inlet or outlet of the filter device. The channel is arranged approximately centrally with the hollow fiber bundle and preferably has a cross-sectional area that decreases in the direction of flow, and also preferably has an outside diameter that is less than the diameter of the hollow fiber bundle. | 09-25-2008 |

20110041388 | METHOD FOR CARRYING OUT PYROLYSIS - The invention relates to a method for carrying out pyrolysis in such manner that a first raw material is fed to a combustion boiler and a second raw material is fed to a pyrolysis reactor which are integrated together, energy fractions are formed from the raw material in the combustion boiler and gaseous and liquid product fractions are formed from the raw material in the pyrolysis reactor by fast pyrolysis. According to the invention, production of the pyrolysis product and energy fractions is controlled by optimizing the selection of the raw material, product distribution and production costs, value and quality of at least one product fraction by varying the process variables, which are selected from the group comprising a first raw material, a second raw material, quantities of the raw materials, selection of additional materials, process parameters, selection of an additional process step, composition and quantity of the carrier gas used, quantity of oxygen, selection of the heat transfer agent and moisture content of the raw material. | 02-24-2011 |
20120060412 | METHOD FOR THE THERMAL TREATMENT OF BIOMASS IN CONNECTION WITH A BOILER PLANT - The invention relates to the improvement of the fuel-properties of biomass in an integrated manner to facilitate storage, shipping and applicability thereof. In the process, biomass ( | 03-15-2012 |
20130219773 | METHOD AND APPARATUS FOR PRODUCING A PYROLYSIS LIQUID - The invention relates to a method for producing a pyrolysis liquid, wherein the pyrolysis liquid is formed by means of pyrolysis from a raw material by forming, in a pyrolysis reactor, a gaseous pyrolysis product by pyrolysis and condensing it in a condenser into a pyrolysis liquid, and feeding circulation gas into the pyrolysis reactor. According to the invention, the circulation gas is conducted by means of a liquid ring compressor into the pyrolysis reactor and purified before being conducted into the pyrolysis reactor, and the pyrolysis liquid is used as the liquid layer in the liquid ring compressor. Further, the invention relates to a corresponding apparatus. | 08-29-2013 |
