Abstract:
    The invention provides a method of purifying compositive gas and a wet type apparatus, which may avoid the squama question in a heat exchanger which is used for recovering the heated and purified gas from pre-purified gas. In this instance, the temperature condition in a heat recovery process is set under a condition where ammonium chloride does not separate out and stuck on the heat transmission face of a heat exchanger and this setting is performed through a preheating process by heater and heat exchanger.
