Method and system for cleaning and upgrading post-consumer and/or post-industrial polyvinylbutyral |
| abstract |
A method and a PVB cleaning and/or upgrading system for cleaning and upgrading post-consumer and/or post-industrial polyvinyl butyral is provided. The system includes an extraction station for extraction with liquid or supercritical carbon dioxide. The extraction station comprises a sealable container with means for introducing pressurized liquid carbon dioxide into the container and means for stirring PVB material. The station further includes transfer means for transferring the pressurized liquid carbon dioxide containing extracted plasticizer and/or contaminants from the container to a distillation unit. The distillation unit separates extracted plasticizer and/or contaminants from the carbon dioxide, by evaporation of the liquefied CO2. The system further includes pressurizing means, such as a compressor, for pressurizing and liquefying of the CO2 evaporated in the distillation unit. |
