Ghassemi, M., K. Crawford, AND S. Quinlivan. ENVIRONMENTAL ASSESSMENT REPORT: LURGI COAL GASIFICATION SYSTEMS FOR SNG. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/7-79/120.
Description:
The report is a compilation and analysis of data on the equipment and processes constituting the Lurgi Substitute Natural Gas (SNG) systems, the control/disposal alternatives for a media, the performance and cost of control alternatives, and present and proposed environmental requirements. It provides the best technical basis currently available for establishing environmental standards for Lurgi SNG plants. Lurgi SNG systems are divided into four operations (coal preparation, coal gasification, gas purification, and gas upgrading) and a number of auxiliary processes (air pollution control, raw water treatment, oxygen production, etc.); each operation consists of a number of processes. Data are provided on the characteristics of input materials, products, and waste streams associated with each process. Pollution control alternatives for air emissions, water effluents, solid wastes, and toxic substances in an integrated facility were examined for performance, costs, energy requirements, and ability to comply with current and anticipated environmental standards. The adequacy of the data was evaluated and the additional data needed to support standards development and enforcement and health and ecological effects and control research and development were identified. On-going and planned programs which may supply some of the needed data are reviewed.
