Abstract
The invention relates to 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 colour 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.
Claims15
A method for sampling a solid sulphur product comprising:
- 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, said reaction fixing the sulphur of the hydrogen sulphide by forming a sulphur-containing solid product which is different in colour from the solid reagent;
- and
- recovering the sulphur-containing solid product.
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;
- and
- means of displaying the change in colouration of the solid reagent in the detachable contact chamber.
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, said contact chamber having a translucent or transparent wall, preferably made of plastic.
