Discussing countermeasures and preventive measures for corrosion and scaling in petrochemical plants

Thread Content

①Optimize the electrodesalination process to ensure that the salt content in the crude oil after desalination meets the specified requirements. At the same time, address the corrosive effects of organic chlorines in crude oil on downstream equipment by developing strategies for their removal, thereby achieving control at the source. ②Monitor the corrosion prevention effectiveness of the process, optimize the selection of additives, and at the same time closely track the analysis data related to corrosion prevention as well as the thinning of equipment and pipelines. Adjust the amount of additives added promptly to ensure effective corrosion control. ③To understand the degree of equipment corrosion, it is recommended to install an online monitoring system to enable the implementation of appropriate protective measures. Establish a corrosion monitoring record-keeping system to regularly collect corrosion data from all facilities across the company. Pay special attention to those equipment where corrosion occurs frequently, is of high significance, and has a wide impact; take preventive measures in advance to avoid serious consequences resulting from corrosion.
