Abstract
A method for cleaning at least first exhaust gas (EG1) and second exhaust gas (EG1). The method comprising scrubbing the first and second exhaust gases (EG1, EG2) in a first and a second scrubber (710, 720) to produce scrubbed first and second exhaust gases (SEG1, SEG2); and conveying at least part of the scrubbed first and second exhaust gases (SEG1, SEG2) to an electrostatic precipitator (100). The method further comprises cleaning one or both of the at least part of the scrubbed first exhaust gas (SEG1) and the at least part of the scrubbed second exhaust gas (SEG2) in the electrostatic precipitator (100) to produce clean exhaust gas (CEG). A system for the carrying out the method.
