Abstract
A catalyst and method of use can involve causing a clean exothermic reaction in a flowline environment. The mixture can include sodium nitrite, an ammonium-based compound, and an activator that can be injected into a fluid flow path. The activator can include an acid that can be generated from a lactone. The fluid flow path can be a pipeline, a flowline, a wellbore, or a subterranean formation. The mixture can cause an exothermic reaction in the fluid flow path and remove, using the exothermic reaction, a damaging material from the fluid flow path.
