API Publ 348 is a technical API document focused on air toxics emission factors for combustion sources using petroleum-based fuels, with emphasis on the API/WSPA approach to developing those factors. For buyers evaluating environmental and operational references, it helps frame how emissions-related data may be prepared and applied in industrial settings where combustion performance and air toxics accounting matter. As a 1998 publication with 133 pages, API Publ 348 can be a useful reference for teams that need a structured basis for technical review, environmental documentation, and internal consistency in emissions-related work.

Overview of API Publ 348

This API Document provides a recognized technical reference for developing emission factors associated with combustion sources fueled by petroleum-based products. API Publ 348 is best understood as a source document for professionals who need a conservative, documented approach to emissions estimation and related technical evaluation. It is relevant where organizations want a common basis for environmental analysis, engineering review, and compliance-oriented documentation. The document’s title indicates a focus on the development method itself, making it especially useful for teams that rely on consistent calculation or reference frameworks.

Common use cases of API Publ 348

API Publ 348 is commonly relevant in refinery, oil and gas, and other petroleum-fueled combustion environments where emission factors may support environmental assessments, reporting support, or internal technical review. Environmental, engineering, operations, and procurement teams may use it to understand the basis behind air toxics factors and to align project documentation with an established API reference. It may also support consultants, technical reviewers, and compliance-related functions that need a documented source for combustion-emission factor development.

Benefits of using API Publ 348

The practical value of API Publ 348 is its ability to provide a consistent technical reference for air toxics emission factor development tied to petroleum-based combustion sources. That can help reduce ambiguity during engineering review, improve documentation quality, and support more reliable internal calculations or comparisons. For organizations handling environmental or process-related data, it can improve traceability and make cross-functional coordination easier between operations, QA/QC, and technical documentation teams. API Publ 348 also helps buyers choose a document that fits a specific emissions-focused workflow rather than a general-purpose reference.
