トランスミッタ&予測ソフト (主として石油精製プロセス) を用いた腐食のリアルタイムモニタリング

抄録

This article introduces real time corrosion monitoring technologies, with unique technologies of transmitter to provide 4 corrosion related signals at the same time where it is located, and of combination of corrosion prediction software, which is mainly for refining process, and software function automatically obtaining required process variables and environmental information from Historian, DCS (Distributed Control System) and LIMS (Laboratory Information Management System) to predict corrosion rate of relevant refining asset or system, continuously.
Real time corrosion monitoring can provide visualized corrosion trend as same as other process values, i. e. temperature, flow rate, pressure, etc. , which can provide availability to manage corrosion by correlating visualized corrosion rate trend with other process variables which to allow refining process operation within IOW (Integrity Operating Windows) of operation conditions within the corrosion allowance range of the asset design life.
