Verfahren und Vorrichtung zur Reinigung von Prozesswasser in einem hydrothermalen Karbonisierungsprozess

Die hydrothermale Karbonisierung erlaubt die Herstellung von Kohle aus Biomasse. Diese Biomasse kann aber zu Beginn des Karbonisierungsprozesse Bestandteile enthalten, die sich für die Karbonisierung nicht eignen. Neben groben Verschmutzungen durch Glasscherben etc. handelt es sich hierbei insbesondere um Sand und Schluff, wobei der Schluff sich durch einfache Filtermethoden aufgrund seiner Feinheit nicht entfernen lässt. Die Erfindung sieht daher eine Entnahme von Prozesswasser aus dem Reaktionsraum vor, welches einer Reinigung in einem Sedimentationsfilter unterzogen wird, nachdem die Karbonisierungsreaktion begonnen hat und der Schluff nicht mehr in der Biomasse festgehalten wird. Das Prozesswasser wird dann wieder in den Reaktionsraum eingestrahlt, um das Biomasse-Prozesswasser-Gemisch in Bewegung zu halten und ein Absetzen des Schluffs am Boden des Reaktionsraums zu vermeiden.

Solar sterilization apparatus for incremental boiling

A water sterilizer powered by solar energy is described. A first check valve allows an increment of untreated water to flow from a reservoir into a boiling chamber where it is heated to boiling, and thus sterilized, by focused solar energy. A second check valve with a higher cracking pressure than the first valve remains closed, holding the increment of untreated water in the boiling chamber until the pressure of steam forces the second valve open, thus evacuating the chamber of now-sterilized water. Once the chamber is evacuated, the second valve automatically closes, and the first valve automatically opens, allowing another incremental sterilizing cycle to begin.

Solar Sterilization by Incremental Boiling

A water sterilizer powered by solar energy is described. A first check valve allows an increment of untreated water to flow from a reservoir into a boiling chamber where it is heated to boiling, and thus sterilized, by focused solar energy. A second check valve with a higher cracking pressure than the first valve remains closed, holding the increment of untreated water in the boiling chamber until the pressure of steam forces the second valve open, thus evacuating the chamber of now-sterilized water. Once the chamber is evacuated, the second valve automatically closes, and the first valve automatically opens, allowing another incremental sterilizing cycle to begin.

Methods for the treatment of ballast water

A process has been developed to selectively dissociate target molecules into component products compositionally distinct from the target molecule, wherein the bonds of the target molecule do not reform because the components are no longer reactive with each other. Dissociation is affected by treating the target molecule with light at a frequency and intensity, alone or in combination with a catalyst in an amount effective to selectively break bonds within the target molecule. Dissociation does not result in re-association into the target molecule by the reverse process, and does not produce component products which have a change in oxidation number or state incorporated oxygen or other additives because the process does not proceed via a typical reduction-oxidation mechanism. This process can be used for the remediation of water, particularly ballast water.
