Abstract

Formulations of seven polyurea-based composite materials are proposed as a matrix to protect the inner surface of oil storage equipment from the formation of pyrophoric deposits. Mechanical or mechano-chemically activated mixtures of activated carbon with titanium dioxide and shungite with titanium dioxide were used as composite fillers. It has been established that the use of the developed composite coatings makes it possible to reduce the rate of hydrogen sulfide corrosion of steel by 26–70 times. It has been shown that coatings in which the filler is an ultrasound-treated mixture of titanium dioxide and activated carbon can perform not only a protective barrier function, but also provide oxidative desulfurization of oil vapor.
