UOP 291-15 is the analytical method for measuring total chloride in alumina and silica-alumina catalysts by microwave digestion and potentiometric titration. It is designed for laboratories that need a reliable way to assess chloride content in catalyst materials, where even low-level ionic contamination can affect product quality and process performance. For refinery and petrochemical teams, this standard supports more consistent sample evaluation, clearer quality documentation, and better comparison of catalyst lots. As a UOP ion analysis method, it fits practical laboratory workflows focused on chemical control and technical review.

Purpose of UOP 291-15

The purpose of UOP 291-15 is to provide a defined measurement approach for total chloride determination in alumina and silica-alumina catalysts. The method combines microwave digestion with potentiometric titration, making it suitable for analytical laboratories that need structured chloride assessment rather than general screening. This is especially relevant when catalyst quality, contamination control, or supplier verification depends on a consistent analytical basis. By focusing on total chloride, the method helps support more dependable laboratory reporting and comparison across catalyst samples.

Laboratory use of UOP 291-15

UOP 291-15 is commonly relevant in catalyst testing laboratories, refinery QA/QC groups, and analytical chemistry teams responsible for material evaluation. It may be used when reviewing catalyst batches, supporting incoming material checks, or documenting chloride levels for internal quality records. Laboratory analysts and technical reviewers often rely on methods like this to keep testing aligned with plant or product specifications. In practice, it supports controlled sample preparation and a repeatable analytical workflow for teams that need dependable chloride data on alumina-based catalyst materials.

Practical value of UOP 291-15

The practical value of UOP 291-15 lies in its ability to support consistent chloride measurement for catalyst materials that are important to refinery and petrochemical operations. Clear chloride data can help teams compare lots, track material quality, and maintain stronger analytical documentation. For laboratory personnel, the method also supports more orderly testing and review when chloride control is part of product qualification or supplier assessment. That makes it useful for day-to-day quality decisions where reliable ionic analysis matters.
