Process Optimization
High-temperature corrosion inhibitors
High-temperature corrosion inhibitors are considered where corrosive refinery streams affect hot process equipment. Selection is based on the corrosion mechanism, stream conditions, metallurgy and downstream requirements.
Discuss your application
Application and function
Documented applications include naphthenic-acid corrosion in hot areas of atmospheric and vacuum crude processing. Identify the corrosive service and equipment requiring protection before selecting treatment.
Film formation is a documented approach within this category. Formulation chemistry, application limits and compatibility should be reviewed within the site’s corrosion-management program.
Information for selection
- Feed analyses, corrosive species and operating temperature profile
- Affected equipment, metallurgy and locations of accelerated corrosion
- Monitoring results, injection facilities and downstream restrictions
Evaluation and technical review
Establish a corrosion baseline before a monitored evaluation. Review corrosion measurements together with operating conditions and feed changes when assessing treatment response.
Feed acidity alone does not describe every condition relevant to selection. Include the circuit’s operating and inspection history in the technical review.
Discuss product selection
Share the application, operating conditions and requirements that matter to your evaluation. Product-specific properties, use guidance and handling information are provided in the relevant product data sheet and safety data sheet.
