Abstract
Elimination and/or mitigation of fouling in a vapor transport systems, such as vent lines and scrubber feed lines may be accomplished using an antifouling additive. The method for employing the antifouling additive includes introducing into the vapor transport system an additive including a polar solvent and corrosion inhibitor wherein: the vapor transport system is substantially water free; the vapor transport system is used to transport acidic materials; the additive is a liquid at vapor transport system operating conditions; and the additive is stable at the vapor transport system operating conditions.
