METHOD OF PREVENTING AMMONIUM CHLORIDE-CAUSED CONTAMINATION AND CORROSION IN CRUDE OIL PROCESSING PROCESSES AND IN PETROCHEMICAL PROCESSES

摘要

FIELD: petroleum processing and corrosion protection.;SUBSTANCE: method envisages addition of agent constituted by choline and its derivatives having one of following formulae: (CH₃)₃N⁺-CH₂CH₂O^-, (CH₃)₃N⁺-CH₂CH₂OH-O^-H, and (CH₃)₃N⁺-CH₂CH₂OH-O^-R, where R represents C₁-C₂₀-alkyl. Ammonium chloride contained in oil reacts with added agent and converts into volatile chloride, which can be removed by steaming or through recirculation of gas.;EFFECT: prevented ammonium chloride-caused contamination and corrosion.;10 cl, 1 dwg, 4 tbl
