Abstract
Methods and dispersing agents for dispersing a polymeric low dose hydrate inhibitor are disclosed. More specifically, the method comprises contacting an aqueous fluid containing a polymeric low dose hydrate inhibitor with a dispersing agent. The dispersing agent can be selected from the group consisting of a C1-C20 alkyl sulfate, a C10-C20 alkyl ether sulfate, a C10-C20 carbonyl sarcosinate, a C10-C20 alkylbenezene sulfonate, a quaternary-ammonium based corrosion inhibitor, a glycol ether, and a combination thereof.
