摘要
The invention concerns a method which consists in: circulating in the internal part of a turbo-machine such as a gas turbine (1) a fluid consisting of a process gas containing a substance in dense state, such as supercritical CO2; dissolving the impurities in the gas turbine (1) internal part, in the substance in supercritical state; recuperating a flow of the supercritical substance containing the dissolved impurities; sampling a fraction (q) of the substance flow containing the impurities; and performing a separation of impurities on the sampled fraction (q) of the substance flow; re-introducing the sampled fraction (q) of the substance flow separated from the impurities into the residual flow (Q-q) containing the impurities, before re-introducing it in the inlet part (11) of the gas turbine. The grime-removing device comprises a circuit for cleaning the gas turbine (11, 12, 13, 14) and a circuit (15, 16, 17) for removing impurities on the sampled fraction (q) on the substance flow containing them.
