Inhibition of corrosion in boilers by polyhydroxy benzene addition |
| abstract |
A method of inhibiting corrosion in a boiler water circuit comprising adding to boiler feedwater containing oxygen an effective amount of a composition comprising a polyhydric benzene compound containing at least three hydroxyl groups and feeding this into the boiler water circuit, in which the polyhydric benzene is generated by subjecting a solution, comprising the corresponding polyhydric benzoic acid compound or polyhydric benzoic acid reverser and a base, to an agent in order to convert at least a portion of the polyhydric benzoic acid compound or precursor to said polyhydric benzene compound, wherein the polyhydric benzene compound is formed substantially immediately before it is fed into the boiler water circuit. It is preferred that the polyhydric benzene compound is a trihydroxy benzene, especially 1,2,3-trihydroxybenzene (pyrogallol). |
