Environmental assessment program for the HYGAS Process

The main objective of the HYGAS Environmental Assessment Program is to systematically obtain and interpret experimental data from the HYGAS pilot plant to estimate pollutant production for demonstration and commercial-scale HYGAS coal gasification plants. Priorities have been established for operating systems for sampling, analyses, and data evaluation to define the fate of potential pollutants generated during pilot plant operation. The assessment methodology for environmental data acquisition and interpretation features these sequential objectives: identification of potential pollutants in plant effluent streams; development of sampling, preservation, and analytical techniques; process unit, stream, and species selection; and quantitative descriptions of significant pollutants.
