Abstract
A method for sampling a sulphur-containing solid product including supplying a gas flow comprising hydrogen sulphide, bringing the gas flow into contact with a solid reagent and reacting the solid reagent with the hydrogen sulphide contained in the gas flow, the reaction fixing the sulphur of the hydrogen sulphide by forming a sulphur-containing solid product which is different in color from the solid reagent, and recovering the sulphur-containing solid product. The invention also relates to a device suitable for the implementation of this method.
Claims17
A device for sampling a sulphur-containing solid product, comprising:
- a contact chamber, comprising a solid reagent, said solid reagent being capable of reacting with hydrogen sulphide and the reaction of the solid reagent with hydrogen sulphide producing a change in colouration and fixing the sulphur of the hydrogen sulphide by forming a sulphur-containing solid product;
- gas flow delivery means, feeding the contact chamber inlet;
- gas flow evacuation means, connected to the contact chamber outlet;
- means of displaying the change in colouration of the solid reagent in the contact chamber;
- means of recovering the sulphur-containing solid product from the contact chamber
- means of displaying the change in colouration of the solid reagent in the contact chamber;
- and
- means of recovering the sulphur-containing solid product from the contact chamber.
