ABSTRACT

The article discusses the existing methods of deactivation of pyrophores-iron sulfides, examines their shortcomings, indicates the number, proportions of effective deactivating components and conditions for their use.

A significant part of fires and explosions in the oil, gas and petrochemical industries are caused by self-igniting pyrophores-iron sulfides. The most common iron sulfide compounds in production are FeS, FeS2; F2S3. These compounds, reacting with oxygen in the air, self-ignite and burn, causing a fire, explosion of technical means used in the transportation and storage of oil and petroleum products.

Taking this into account, an effective method of decontamination of pyrophoric deposits has been developed. The proposed composition transforms pyrophoric substances into non-pyrophoric ones, being a foaming agent. The process is characterized by the simplicity of its own method of preparation and use, significantly lower cost.

Pyrophor-a composition passivating iron sulfide, consists of sodium salt (ntnd) naphthenic acid and an aqueous solution of foam-stabilizing polyacrylamide (paa).

Keywords: Pyrophor, iron sulfide compounds, sulfide compounds of petroleum products, naphthenic acids, inhibitors, polyacrylamide (paa), foaming agent reactor.
