This report contains the results of a study to determine the range of compositions for a number of compounds in typical refinery process streams. Data representing 31 refineries, over 20 processes, and over 50 process streams was contributed by the project participants: Amoco, Arco, BP, Chevron, Exxon, Mobil, Shell and Texaco. The results of this project will be of use in estimating the emissions of specific compounds, in preparing permit applications and in other environmental control activities. Neither the Petroleum Environmental Research Forum (PERF) or the project participants make any claims as to the suitability or acceptability of the stream composition data reported herein for specific reporting or regulatory purposes. This project was undertaken to provide an improved database for determining the composition and estimating the emissions of 24 regulated compounds from typical refinery process streams. Some of these compounds are included in the 1990 Clean Air Act Amendments Title III List of Hazardous Air Pollutants and the others are among those compounds to be regulated under the Accidental Release provisions of Title III. The results presented in this report represent a larger quantity of data than that available to any of the participant individually and will, therefore, result in improved emission estimates and a better understanding of the variability in process stream compositions. Concentrations of specific compounds are presented both in tabular form and graphically. For each process unit and stream, the data include the minimum, maximum and most likely concentrations for each compound. A second listing presents the data by compound so that potential emission sources can be more easily identified and evaluated. The data are presented graphically by process unit and stream, showing all of the data and the most likely value for each compound. Passage of the Clean Air Act Amendments of 1990 created a number of new compliance challenges for the U.S. petroleum industry. In order to provide improved approaches to meeting these challenges, and to allow leveraging of research expenditures, a number of the members of the Petroleum Environmental Research Forum (PERF) formed the Cooperative Air Program (CAP). The CAP consists of a number of individual research projects in twelve areas including emissions monitoring, dispersion modeling, VOC and NOx emission control, pollution prevention and others. Refinery stream speciation is one of the CAP project areas. The objective of the refinery stream speciation project was to develop industry representative concentration profiles for process streams. Reasons for undertaking this activity included the desire for improved emissions estimates for determination of regulatory applicability, operating permit preparation and compliance, and risk assessment determinations. There was concern that the previously available speciation data was not representative of averages or the ranges of specific compounds in current refinery operations. The refinery stream speciation profiles presented in this document were developed from stream sampling conducted by each of the participating companies: Amoco, Arco, BP, Chevron, Exxon, Mobil, Shell and Texaco. The identities of specific companies and refineries are coded in the raw data listing for confidentiality. Each company representative provided guidance on the program scope and objectives, the data collection effort, the data analysis procedures, and the reporting of final results.
