UOP 818-20 is the UOP method for Thiosulfate in Lean Amine Solutions, giving laboratories a focused way to evaluate thiosulfate levels in this process stream. For refineries and chemical operations that use lean amine systems, this type of analysis can support product quality review, process monitoring, and technical documentation. UOP 818-20 is a practical reference for teams that need a consistent laboratory method when checking amine solution condition and comparing results across internal testing programs.

UOP 818-20 method scope

This UOP test method is centered on the analytical determination of thiosulfate in lean amine solutions. Its scope is aligned with laboratory measurement work rather than broad process evaluation, making it relevant when a facility needs a defined method for sample review and quality control. As a petroleum and chemical laboratory method, UOP 818-20 supports controlled analysis of amine-based samples where thiosulfate monitoring may be important for operational oversight and routine documentation.

Where is UOP 818-20 used?

UOP 818-20 is commonly used in refinery and petrochemical laboratory settings where lean amine solutions are part of gas treating or related process systems. It may be selected by laboratory analysts, QA/QC personnel, technical reviewers, and process engineers who need reliable data for amine system monitoring. The method is also useful in internal testing workflows where sample results must be reviewed, compared, and recorded in a consistent technical format for plant support or quality verification.

Why professionals use UOP 818-20

Professionals rely on UOP 818-20 when they need a clear laboratory method for thiosulfate measurement in lean amine solutions. In day-to-day work, that can help with consistency in sample evaluation, support comparisons between batches or operating periods, and strengthen technical records used in refinery quality control. For organizations managing process chemistry, the method offers a practical way to organize analytical work around a specific contaminant or species of interest without adding unnecessary complexity to the test program.
