Title:
COMBINATION PRODUCTS CONTAINING ANTI-AGGLOMERANT LOW DOSE HYDRATE INHIBITORS AND CORROSION INHIBITORS WITH IMPROVED CORROSION RESISTANCE
Document Type and Number:
WIPO Patent Application WO/2024/054812
Kind Code:
A3
Abstract:
Hydrate inhibitor and corrosion inhibitor composition are disclosed and include from about 10 wt-% to about 99.9 wt-% of an anti-agglomerant low dose hydrate inhibitor (AA-LDHI), wherein the AA-LDHI is a zwitterionic compound or a cationic ammonium compound; from about 0.01 wt-% to about 50 wt-% of a corrosion inhibitor, and at least one additional functional ingredient, solvent, or a combination thereof. Methods for inhibiting corrosion and formation of gas hydrate agglomerants in a fluid are disclosed and include contacting the fluid with a hydrate inhibitor and corrosion inhibitor composition or contacting the fluid with an AA-LDHI, wherein the AA-LDHI is a zwitterionic compound or a cationic ammonium compound, and a corrosion inhibitor, wherein the AA-LDHI and corrosion inhibitor are provided at a weight ratio of about 1:0.001 to about 1:1, and wherein the composition inhibits general and localized corrosion and formation of gas hydrate agglomerants in the fluid.
