UOP 344-87 is the method buyers look for when they need a technical standard for Moisture in Hydrocarbon Streams Using an On-Line Analyzer. It is aimed at evaluating moisture levels in flowing hydrocarbon service with an automated analyzer approach, making it relevant where continuous or near-continuous observation supports product quality and process awareness. For laboratory analysts, refinery QA/QC teams, and technical reviewers, this method can help align test selection with operational monitoring needs. As a UOP method, UOP 344-87 supports standardized documentation and more consistent moisture-related assessment in petroleum and chemical work.

UOP 344-87 method scope

This UOP Test Method focuses on the measurement of moisture in hydrocarbon streams using an on-line analyzer. The title indicates an instrumental, process-oriented approach rather than a manual bench test, which makes it suitable for analytical workflows where timely moisture information is important. UOP 344-87 is therefore most relevant when users need a standardized way to evaluate water content in hydrocarbon service and compare results within refinery or plant documentation. It is a practical reference for teams selecting a method for routine monitoring or technical review.

Where is UOP 344-87 used?

UOP 344-87 is commonly used in refinery laboratories, process support settings, and petrochemical operations where hydrocarbon moisture monitoring matters to product handling or quality control. It may be reviewed by laboratory analysts, process engineers, petroleum specialists, and QA/QC personnel who need a recognized method for on-line moisture measurement. The standard is especially relevant in environments where streams are checked during production or transfer, and where consistent analyzer-based results help support operating decisions and documentation. It fits workflows that depend on practical, repeatable moisture assessment in hydrocarbon systems.

Why professionals use UOP 344-87

Professionals use UOP 344-87 because moisture control can affect product quality, process stability, and technical confidence in hydrocarbon stream evaluation. An on-line analyzer method helps teams obtain moisture information in a format that supports faster review than intermittent manual testing alone. That can be valuable for comparing stream conditions, verifying operating trends, and maintaining consistent laboratory or plant records. For organizations responsible for refinery quality control or technical oversight, the method provides a clear standard for documenting moisture-related measurements and aligning internal practice with a recognized UOP reference.
