| With the progress of oil production technology, the quality of the crude oil also decreased, while sulfur and acid quantity of crude oil is high. These will increase the refining chemical equipment corrosion. Equipment corrosion will produce safe hidden trouble, reduce the life of equipment and increase equipment unplanned maintenance. In order to ensure normal production of oil refining equipment and safe and long period operation, corrosion monitoring of oil refining equipment is particularly important. Corrosion monitoring technology has wide application prospect in the prevention of accidents, prediction life of equipment, analysis the reasons of equipment corrosion, improvement of the equipment running status and improvement of the reliability of equipment, etc.This paper have been collected the corrosion information and evaluated the possibility and reliability of online corrosion monitoring system based on Yan’an Refinery200tons/year RFCC. The important corrosion parts, the couses and types of corrosion are been analyzed to determine the corrosion monitoring position. The widely used corrosion monitoring technology is researched to seclect the best method of RFCC corrosion monitoring. It is under the installation position, the instrument’s performance, useful time and economy to selecte corrosion monitoring equipment which complete the overall design of RCFF corrosion monitoring system. Finally, it reaches the corrosion monitoring purposes to ensure the RFCC’s safety.It makes a great significance in comprehensive understand the various corrosion informations of RCFF, ensure the possibility and reliability of online corrosion monitoring and overall desiogn of cossosion monitoring system. |
