UOP 958-98 is a laboratory test method for Ammonia in Hydrocarbons, helping analysts evaluate whether ammonia is present in hydrocarbon samples and how that result may affect product handling, quality review, and process decisions. For refinery and petrochemical teams, this kind of measurement is useful when assessing sample cleanliness, potential contamination, and compatibility with downstream operations. UOP 958-98 supports technical documentation and routine laboratory work where ammonia monitoring is part of product evaluation or troubleshooting.

UOP 958-98 method scope

This UOP Test Method is centered on the determination of ammonia in hydrocarbon materials, making it relevant to analytical chemistry workflows in petroleum and related processing environments. UOP 958-98 is typically used as a focused measurement method rather than a broad compositional survey, so it fits situations where a specific ammonia-related check is needed for a sample or product stream. The official title indicates a practical laboratory purpose: identifying and measuring ammonia content in hydrocarbons for quality and technical review.

Where is UOP 958-98 used?

UOP 958-98 is commonly used in laboratory settings that support refinery operations, petrochemical production, and fuel or hydrocarbon quality assessment. It may be relevant to laboratory analysts, QA/QC teams, analytical chemists, and technical reviewers who need a dependable method for ammonia-related sample evaluation. In practice, it can support routine screening, investigation of process upsets, and review of product or stream suitability where ammonia presence matters to operations or documentation.

Why professionals use UOP 958-98

Professionals use UOP 958-98 because ammonia in hydrocarbons can be an important quality and operational indicator, especially when consistency and clean sample handling are priorities. The method helps teams compare results across batches, support internal specifications, and maintain clearer laboratory records for technical decision-making. For organizations managing refinery or petrochemical workflows, a defined UOP method improves consistency in testing and makes ammonia-related review more straightforward across laboratory and process functions.
