UOP 384-76 is a laboratory test method for determining nitrogen in petroleum distillates and heavy oils by acid extraction or the direct Kjeldahl procedure. It is relevant when buyers need a controlled way to assess nitrogen content in petroleum samples that may affect refining performance, product quality, or analytical documentation. For laboratories handling distillate streams or heavier oil materials, this method supports structured sample evaluation and comparison. UOP 384-76 is a practical reference for teams that need a recognized petroleum testing method tied to nitrogen measurement.

Overview of UOP 384-76

This UOP method focuses on the analytical determination of nitrogen in petroleum distillates and heavy oils. The title indicates two recognized laboratory approaches: acid extraction and the direct Kjeldahl procedure, both used for nitrogen evaluation in petroleum-related samples. As a UOP test method, UOP 384-76 serves as a technical document for laboratories that require a standardized framework for assessing nitrogen content. It is most useful where nitrogen data must be reviewed in a consistent, method-based context for petroleum and chemical analysis work.

Laboratory use of UOP 384-76

UOP 384-76 is commonly suited to refinery laboratories, petroleum testing facilities, and analytical groups responsible for sample review and quality verification. Laboratory analysts and QA/QC teams may use it when nitrogen results are needed for distillate products or heavier oil samples, especially in routine characterization or technical comparison work. It can also support chemists and technical reviewers who document analytical results for internal evaluation, product assessment, or specification-related review. The method fits well into established petroleum laboratory workflows.

Why UOP 384-76 matters in day-to-day work

In day-to-day practice, UOP 384-76 helps teams apply a defined analytical approach to nitrogen testing rather than relying on informal or inconsistent procedures. That matters for result consistency, lab-to-lab comparison, and clearer technical records. For refinery and laboratory personnel, the method can support routine quality checks, product evaluation, and interpretation of sample data tied to petroleum distillates and heavy oils. UOP 384-76 is useful where reliable nitrogen information is part of operational decisions or method documentation.
