  • Method for monitoring the course of a process using a reactive gas containing one or several hydrocarbons
    Patent number: 7241470
    Abstract: The method applies to a process such as cementation or chemical vapor infiltration or deposition, the process being carried out in an oven and the method comprising setting operating parameters of the oven, introducing a reagent gas into the oven, the reagent gas containing at least one gaseous hydrocarbon, and extracting from the oven an effluent gas containing reaction by-products of the reagent gas. The effluent gas is subjected to washing in oil that absorbs tars contained in the effluent gas, and information about the progress of the process is obtained by measuring the quantity of tar absorbed by the oil.
