UOP 291-13 defines a laboratory method for measuring total chloride in alumina and silica-alumina catalysts by microwave digestion and potentiometric titration. For buyers evaluating catalyst quality or contamination control, this standard supports clear chloride assessment in routine analytical work. UOP 291-13 is relevant where catalyst composition and cleanliness affect process performance, product consistency, or material qualification. It is a practical technical document for labs that need a controlled, repeatable way to review chloride content and support refinery or petrochemical sample evaluation.

UOP 291-13 analytical scope

This UOP ion analysis method is focused on the determination of total chloride in solid catalyst materials, specifically alumina and silica-alumina catalysts. The title indicates a workflow based on microwave digestion followed by potentiometric titration, which places the method in a laboratory analytical chemistry context rather than a process test. UOP 291-13 is therefore suited to measuring chloride in prepared samples for quality control, material comparison, and technical review. It is especially relevant when chloride level needs to be checked as part of catalyst characterization or acceptance testing.

Where is UOP 291-13 used?

UOP 291-13 is commonly used in catalyst testing laboratories, refinery QA/QC groups, and analytical teams supporting petrochemical or hydroprocessing operations. It may also be reviewed by technical service personnel, laboratory chemists, and process engineers who need chloride data for catalyst assessment or documentation. Because the method targets alumina and silica-alumina catalysts, it fits workflows where material evaluation, incoming inspection, or batch comparison are part of daily lab activity. UOP 291-13 helps teams align analytical results with internal quality and performance checks.

Why labs rely on UOP 291-13

Labs rely on UOP 291-13 because it provides a defined approach for chloride measurement in catalyst materials, which supports consistency across routine testing and technical reporting. In practical use, that matters when teams need dependable data for product qualification, sample comparison, or investigation of catalyst-related issues. The method also helps maintain clearer laboratory documentation by standardizing how total chloride is determined. For organizations managing refinery or petrochemical analytical programs, UOP 291-13 can support more confident review of material quality and test-to-test comparability.
