Claims20
A method of inhibiting corrosion in aqueous brine solution systems wherein a brine solution containing at least 100,000 ppm of a salt from the group consisting of calcium chloride, calcium bromide, potassium chloride, potassium bromide, lithium chloride, magnesium chloride, magnesium bromide, sodium chloride, and sodium bromide is treated with at least 200 ppm by weight gluconate and at least 200 ppm of an alkane polyol selected from the group consisting of sorbitol and mannitol.
A method of inhibiting corrosion in brine solution refrigeration systems comprising treating the brine solution with at least about 200 ppm gluconate, at least about 200 ppm sorbitol, at least about 100 ppm of borax, and at least about 5 ppm of a corrosion inhibitor for yellow metals.
