Abstract
A method is disclosed which limits soiling of internal turbomachine parts from dirt originating with process gas. In between at least two successive faces in which the turbomachine is operated normally, and during which time only process gas is introduced into the inlet of the turbomachine, a cleaning phase is initiated. During this phase, a substance in a dense state is introduced at the inlet which is capable of dissolving the dirt on internal parts of the turbomachine. Process gas and the dirt dissolving substance are separated.
