Developing New Innovative Descaling and Corrosion Inhibiting Solutions to Protect Steel Equipment in the Oil and Gas Industry

摘要

Previous studies have shown that corrosion is very costly and has a major impact on the economies of industrial nations.It is estimated that the annual cost of corrosion worldwide is over 3％ of the world's GDP.In the oil and gas industry alone,corrosion costs billions of dollars a year.For that,corrosion control and mitigation technologies are of great importance.It is also our duty to protect the environment,preserve resources,and protect our fellow human beings.Descaling and corrosion inhibiting methods are widely used in many industries,like in the oil and gas industry.It is very important for any industry to clean the fire tube boilers,heat exchangers,and before commissioning to clean the pipes.For the oil and gas industry,in particular,it is extremely important to acidize the wells while keeping the downhole pipe safe.In this study,a new highly effective industrial cleaning solution which is effective in descaling without causing corrosion was found which comprises a mixture of hydrochloric acid,hydrofluoric acid,one or more chelating agents,a surfactant,a copper complexing agent,and a nontoxic acridine orange inhibitor,which serves to block the anodic and cathodic sites on the steel surfaces of the process equipment.
