20130214202 | PREPARATION OF AN AMINE BASED SOLVENT CONTAMINATED BY THE INTRODUCTION OF SULFUR OXIDES - A method for processing an amine-based solvent contaminated by the introduction of sulfur oxides is provided. A potassium compound is introduced into a contaminated solvent, and the contaminated solvent is cooled so that a solubility of a potassium sulfate becomes less than a specified concentration of potassium sulfate. Further, an oxidizing agent is introduced into the contaminated solvent so that a potassium sulfite is oxidized to potassium sulfate. The potassium sulfate is filtered out, wherein a prepared solvent is formed. Further, a device for processing an amine-based, sulfur oxide-contaminated solvent is provided. | 08-22-2013 |
20150075376 | SEPARATION DEVICE FOR CARBON DIOXIDE, METHOD FOR THE OPERATION THEREOF, AND SEPARATING UNIT - A device and method for separating off carbon dioxide is provided, including an absorption unit, desorption unit assigned thereto and a separation unit for separating off salts from a scrubbing solution. The absorption and desorption units are connected to each other via a first conduit for a regenerated scrubbing solution and a second conduit for a loaded scrubbing solution. The separation unit includes a crystallizer for forming salt crystals and a first separator unit on the downstream side for separating off salt crystals. A separation unit is provided for separating off salts from a scrubbing solution, having a crystallizer and a first separator unit downstream thereof. The crystallizer has a crystallization chamber for forming salt crystals and a countercurrent classifier for separating salt crystals according to particle size. A first branch conduit is connected to the crystallization chamber, which opens out into the countercurrent classifier via a second separator unit. | 03-19-2015 |
