Method and device of a turbomachine of the preferred to limit the fouling of the internal parts of the turbomachine by means of the dirt from the gas of this

摘要

The invention concerns a method which consists in: successively carrying out the normal operating phases of the turbo-machine (3) during which in the turbo-machine (3) intake, only process gas is introduced and cleaning phases during which is introduced in the process circuit (1), at the turbo-machine (3) intake (4), a substance in dense state such as CO2, supercritical substance capable of dissolving the impurities. The cleaning can be performed with or without continuous recuperation of the substance in dense state dissolving the impurities.
