Environmental Permitting of a Low-BTU Coal Gasification Facility
MetadataShow full item record
The high price of natural gas and fuel oil for steam/power generation has alerted industry's decision makers to potentially more economical ways to provide the needed energy. Low-Btu fuel gas produced from coal appears to be an attractive alternate that merits serious consideration since only relatively small modifications to the existing oil or gas burner system may be required, and boiler derating can be minimized. The environmental permitting and planning process for a low-Btu coal gasification facility needs to address those items that are not only unique to the gasification process itself, but also items generic to conventional firing of coal. This paper will discuss the environmental data necessary for permitting a low-Btu gasification facility located in the State of Louisiana. An actual case study for a 500,000 lb/hr natural gas-fired process steam plant being converted to low Btu gas will be presented. Typical air, water and solid waste effluents that must be considered will also be described.
