| 摘要 |
A method of inhibiting carbonate stress corrosion cracking is determined to involve the addition of certain treatment chemicals to refinery process streams containing at least 1 of the volatile chemicals, ammonia, carbon dioxide, hydrogen sulfide, hydrogen cyanide, and water. The treatment chemical is preferably a fatty imidazoline compound or fatty amides or fatty esters or mixtures thereof. The imidazoline compounds and the amide/esters are formed by reacting tall oil fatty acids, naphthenic acids, or mixtures thereof with essentially linear heterochemicals containing amine or alcohol functionality.
