ONLINE, REAL-TIME CORROSION MONITORING FOR IMPROVING PIPELINE INTEGRITY - TECHNOLOGY AND EXPERIENCE

摘要

This paper describes the evolution in corrosion monitoring technology from off-line historical applications to online, real-time use. It describes the results of laboratory and field investigations performed to characterize the corrosion behavior in inhibited multiphase and dehydrated transport lines, and water injection facilities. The emphasis of the discussion is modern automated electrochemical monitoring instrumentation and methodologies incorporating multiple techniques. The paper describes recent advances in technology (e.g. microchip encoding and distributed hardware with direct to a plant distributed control system -
