Received August 4, 2006 Abstract — The causes of the formation and the conditions for self-ignition of pyrophoric deposits in the vapor zone of tanks during the storage of sour crude oil were considered. It was demonstrated that creation of an oxygen-free atmosphere inside oil storage tanks seems to be the most promising approach to prevention of selfignition and corrosion. This approach was effected in practice by supplying oil tanks with nitrogen from a membrane gas separator. PACS numbers: 81.65.Kn DOI: 10.1134/S0033173207030113
