The Development of Corrosion Inhibitors With Low-Environmental Toxicity.

Abstract

This paper discusses the advantages of corrosion inhibitor treatments for oil production applications. It reviews the current direction of legislation concerning the di scharge of oi 1 production chemical s into the environment. It details studies undertaken which show that many existing corrosion inhibitors are toxic towards the marine organisms tested. New chemistries have been developed which display excel 1 ent corrosion inhibition properties and which are significantly less toxic.See, for example: Silverman D. C., Corrosion, 44 (1988) 42. Organisation for EconomicCooperation and Development . r Sources of their toxicity were identified.

Investigation of Low-Toxic Organic Corrosion Inhibitors for CO2 Separation Process Using Aqueous MEA Solvent

“…[2][3][4] Of these alternatives, the use of corrosion inhibitors is considered the most economical technique for corrosion control. [5][6][7][8] Various corrosion inhibitors have been developed, patented, and commercialized by many major chemical companies for uses in amine treating units. The patented organic inhibitors include thiourea and salicyclic acid, while the inorganic inhibitors are vanadium, antimony, copper, cobalt, tin, and sulfur compounds.…”

“…In Europe, for example, the European Economic Community (EEC) has charged the Paris Commission (PARCOM) with providing a framework for legislation. 6,10 Other highlighted regulations include the Emergency Planning and Community Right to Know Act of 1986, regulations adopted by the U.S. Occupational Safety and Health Administration (OSHA) in 1993, and adoption of the Chemical Hazard Assessment and Risk Management (CHARM) model in the U.K. and other European countries. 11 In Canada, uses of toxic substances including several inorganic heavy metals are controlled under the Canadian Environmental Protection Act (CEPA).…”
