The objective of the project is, on the one hand, the useful use of the by-product char from the biomass gasification process of Torrgas Delfzijl and, on the other hand, to improve the business case of the application of the digester. The project opted for the extraction, cooling and upgrading of char for sales to activated coal. This renegotiation of the char requires two additional process steps, which are innovative in their application.In this project, a unique extraction system in combination with a cooling unit is being developed for extraction and marketing of the produced char from the biomass digester and tested behind a 700 kW two-stage grinder, which acts as a pilot plant for its technology. The processes must meet specified requirements for the quality of the char and (active) carbon, explosion protection and process stability of the digester. The char, which is used as a precursor for the production of (active) coal, has such a yield that the required amount of SDE+ can be reduced in the event of lasting, high profitability of the digester. It is foreseen that the biocoal will be used in the production process of ESD-SIC in Delfzijl to replace petroleum coke.The activities within the project focus on the extraction of the char from the pyrolysis reactor and the cooling to a temperature below the spontaneous ignition temperature. The innovative character is based on the extraction and cooling of the char, on the other hand by the oxygen-free processing in the process steps. In the first phase, the quality requirements for the char will be mapped out. These requirements form the basis for further processing of char into activated carbon and lay down the framework conditions for the subsequent stages. It examines which control on operating parameters of the grinder is needed to obtain the desired quality of the char. For this purpose, several activated carbon conversion tests are carried out, followed by characterisation of the activated carbon on a laboratory scale. The quality requirements for the char are laid down. The framework conditions for the engineering and construction of the char extraction unit and cooling unit are completed. In phase two, the char extraction and cooling installations are engineered and built. In phase three, the installation is extensively tested. The optimal settings of the pyrolysis reactor and reprocessing unit shall be determined and recorded. A first design is being realised for the large-scale 10 MW digester in Delfzijl. The project will be completed by reporting and disseminating the project results. (English) | |||||||||||||||

Het doel van het project is enerzijds de nuttige inzet van het bijproduct char uit het biomassavergassingsproces van Torrgas Delfzijl en anderzijds het verbeteren van de business case van de toepassing van de vergasser. In het project is gekozen voor uittrekken, koelen en opwaarderen van char voor afzet richting actief kool. Voor deze verwaarding van de char zijn twee extra processtappen nodig, die innovatief zijn in hun toepassing.In het onderhavig project wordt een uniek uittreksystem in combinatie met een koeleenheid ontwikkeld voor extractie en afzet van de geproduceerde char uit de biomassavergasser en getest achter een 700 kW tweetrapsvergasser, die als pilot plant voor haar technologie fungeert. De processen dienen te voldoen aan gestelde eisen voor kwaliteit van de char en (actieve) kool, explosieveiligheid en processtabiliteit van de vergasser. De char, die ingezet wordt als precursor voor de productie van (actieve) kool, kent een dusdanige opbrengst dat de benodigde hoeveelheid SDE+ verminderd kan worden bij blijvende, hoge rentabiliteit van de vergasser. Het is voorzien dat de biokool wordt ingezet in het productieproces van ESD-SIC in Delfzijl ter vervanging van petroleum cokes.De activiteiten binnen het project richten zich op de extractie van de char aan de pyrolyse reactor en de koeling tot een temperatuur onder de spontane ontbrandingstemperatuur. Het innovatieve karakter wordt enerzijds gevormd door uittrekken en koelen van de char, anderzijds door de zuurstofvrije verwerking in de processtappen. In de eerste fase worden de kwaliteitseisen voor de char in kaart gebracht. Deze eisen vormen de basis voor de verdere verwerking van char tot actieve kool en leggen de randvoorwaarden voor de volgende fasen vast. Er wordt onderzocht welke sturing op bedrijfsparameters van de vergasser nodig zijn voor het verkrijgen van de gewenste kwaliteit van de char. Hiervoor worden diverse actieve kool omzettingsproeven uitgevoerd, gevolgd door karakterisering van de actieve kool op laboratoriumschaal. De kwaliteitseisen voor de char worden vastgelegd. De randvoorwaarden voor de engineering en bouw van de char uittrekeenheid en koelunit worden invuld. In fase twee worden de installaties voor uittrekken en koelen van de char ge-engineerd en gebouwd. In fase drie wordt de installatie uitvoerig beproeft. De optimale instellingen van de pyrolyse reactor en opwerkeenheid worden vastgesteld en vastgelegd. Er wordt een eerste ontwerp gerealiseerd voor toepassing bij de grootschalige 10 MW vergasser in Delfzijl. Het project wordt afgerond middels rapportage en disseminatie van de projectresultaten.
