Patent ID: 8246857

Claim:
A method for inhibiting corrosion, comprising: adding to an aqueous system a composition, comprising: (a) a glycoside component A comprising at least one glycoside of the formula: R(OG) x wherein R is an aliphatic hydrocarbon radical having 1 to 25 carbon atoms or is a radical of formula R 1 (OR 2 )n which does not have more than 25 carbon atoms and wherein n =0 to 24 and R 1 and R 2 are aliphatic hydrocarbon radicals; G is a saccharide selected from the group consisting of fructose, glucose, mannose, galactose, talose, gulose, aliose, altrose, idose, arabinose, xylose, lyxose, ribose and alkoxylated derivatives thereof; and x is 1 to 30; (b) an aspartate component B comprising at least polyasparatic acid (c) a dialkyl glycol component C; and (d) at least one defoamer; and the corrosion inhibition method is corrosion inhibition in one selected from the group consisting of oil industry and gas industry.
