Corrosion Prevention in Processing Sour Crudes★

Progress in the development of sour corrosion inhibitors: Past, present, and future perspectives

“…The 1900s were dominated by the use of inorganic corrosion inhibitors for the protection of carbon steel against sour corrosion [53,54]. Nevertheless, it is on record that an organic corrosion inhibitor was discovered as early as 1945.…”

Cements

“…Gunite linings, while not acidproof, find use in equipment subjected to certain corrosive conditions-for example, these linings give satisfactory service in storage tanks, soaking drums, and primary bubble towers for sour crude oil service (11). Gunite linings are also serviceable for handling sodium hypochlorite solutions.…”
