UOP 286-13 is a laboratory test method for Free Sulfur in Distillates by Mercury Number, used to evaluate whether distillate samples contain free sulfur that may affect product handling, quality, or downstream performance. For laboratories and refinery teams, this standard helps define a focused analytical check on sulfur-related behavior in distillate materials. It is most relevant when a buyer needs a documented UOP method for petroleum testing, sample review, or quality verification tied to sulfur assessment in refined products.

Purpose of UOP 286-13

The purpose of UOP 286-13 is to provide a standardized measurement approach for free sulfur in distillate samples using the mercury number concept. As a UOP Test Method, it supports consistent analytical evaluation in petroleum and chemical laboratory settings where sulfur content or sulfur-related characteristics must be checked in a controlled way. This makes it a practical reference for method selection, technical documentation, and comparison work when assessing distillate quality against internal or external requirements.

Laboratory use of UOP 286-13

UOP 286-13 is commonly suited to laboratory workflows involving distillate testing, refinery quality control, and analytical review of fuel or petroleum-derived samples. Laboratory analysts, QA/QC personnel, and technical reviewers may use it when free sulfur determination is part of routine product assessment or investigation. It can also support chemical and petroleum teams that need a recognized method for documenting sulfur-related results in distillate streams, particularly where consistent interpretation across samples is important.

Practical importance of UOP 286-13

In day-to-day operations, UOP 286-13 helps teams maintain a clear and repeatable approach to checking free sulfur in distillates. That matters for product comparison, quality verification, and analytical recordkeeping, especially when results are used to support release decisions or technical reviews. For refinery laboratories and fuel testing groups, a defined UOP method improves consistency across testing programs and provides a dependable reference for internal reporting and specification-related work.
