Assessment of Hydrocarbon and Particulate Emissions Control and Wastewater Treatment Technology for the Solvent Refined Coal-II Process. Volume II. Technical Report

摘要

The Solvent Refined Coal-II (SRC-II) process provides a significant alternative to importing oil by producing oil derived from our abundant coal reserves. The primary product of this process is a low-sulfur distillate fuel suitable for burning in utility boilers. On the basis of preliminary design and pilot plant data, controlling particulates and hydrocarbons from the SRC-II plant is of primary concern. In addition, wastewater treatment technology should be studied further, as only limited data were derived from the experience at the pilot plant. This report examines the SRC-II process utilizing the preliminary design developed by Stearns-Roger, Incorporated. That process design uses noncatalytic, direct hydrogenation to liquefy up to 6078 metric tons per day of coal. This report proceeds through a process description of the SRC-II process based on the Phase Zero SRC-II Demonstration Project, estimates the air pollutant emissions from point and fugitive sources, characterizes wastewater streams from the process, and discusses available control technologies which can be applied to the streams. The costs of the different control technologies are also discussed. Preliminary and detailed screening analyses were performed to investigate the air quality problems to plant personnel and the surrounding community. Potential health risks from particulates and hydrocarbon emissions have been assessed based on studies undertaken at different laboratories in the country. Finally, a summary of environmental impacts and control technology consideration is presented. The summary includes research and development needs in the area of emission factors, waste stream characterization and control technologies. 40 references, 27 figures, 117 tables.
