The aspects of chemical desactivation of the pyrophoric sediments using sulfoxides on the oil production facilities during the exploitation of the vertical cylindrical vessels (VCV), which are intended for containing sulphurous oils, are studied in this article. It is found out that sulfoxides, either individual substances or their mixtures, can effectively passivate pyrophoric iron sulphides. The laboratory express-method for separation the pyrophoric sediments, containing pyrophoric iron is also developed.
