Abstract (en)
The method involves subjecting contaminant (V) with dry ice for cooling and embrittling the contaminant, where the dry ice is produced by a device (10) for removing the contaminant from a surface (O). The embrittled contaminant is removed by mechanical removal by a brush (5) of the device. The brush is moved by the device for acting on the contaminant. Liquid carbon dioxide in a dry ice forming region (30) is expanded for producing the dry ice so that a mixture of the dry ice and gaseous carbon dioxide is obtained. The mixture in the dry ice forming region is expanded by a turbine (2). An independent claim is also included for a device for removing contaminant from a surface.
