Document Type and Number:
Japanese Patent JPH03504098
Kind Code:
A
Abstract:
In the cleaning of process gases, such as flue gases, containing heavy metals, especially mercury and/or mercury compounds, and possibly also containing acidifying gases, such as hydrogen chloride and/or sulphur dioxide, the process gases are contacted in a contact reactor (6) with an aqueous solution or an aqueous suspension containing a first absorbent material which is reactive with the heavy metals of the process gases and is in the form of one or more metal sulphides, preferably sodium sulphide, for separating the heavy metals from the process gases. The water is then supplied in such an amount and in such a finely divided state that it is completely evaporated when contacting the process gases.
