API Publ 4704 is a technical API document focused on a gas fired heater test report for Site B, addressing characterization of fine particulate emission factors and speciation profiles from stationary petroleum industry combustion sources. For buyers evaluating API Publ 4704, this means a practical reference for understanding how combustion-related particulate emissions were assessed in a petroleum industry setting. It can help teams review environmental data, align technical documentation, and support informed decisions where heater emissions and source characterization matter in operations or project work.

API Publ 4704 standard overview

API Publ 4704 provides technical background associated with measured particulate emissions from gas fired heater service, with emphasis on test report findings and emission factor characterization. As an API document, it serves as a specialized reference rather than an operating manual, making it useful for professionals who need a credible basis for review or comparison. The official title indicates coverage of fine particulate emission factors and speciation profiles, which may be relevant when evaluating combustion source data, environmental reporting, or facility documentation in petroleum industry applications.

Where is API Publ 4704 used?

API Publ 4704 is commonly used in petroleum industry settings where stationary combustion sources and gas fired heaters are part of facility operations, such as refining or process plant environments. It may be referenced by environmental, engineering, operations, maintenance, and technical documentation teams when reviewing test reports or supporting emissions-related assessments. Procurement and project teams may also use it as a technical reference when documenting equipment-related environmental performance or aligning internal records with a defined API source document.

Practical importance of API Publ 4704

API Publ 4704 matters because it gives organizations a structured technical reference for understanding particulate emissions from gas fired heater service. That can support clearer internal communication, more consistent review of test data, and better alignment between engineering, operations, and environmental functions. For companies managing combustion sources, the document may help with technical validation, reporting support, and documentation control. Its value is strongest where teams need a reliable API-based source for comparing emissions-related information and maintaining consistent records across plant or project activities.
