The coal conversion complex is designed for a feed rate of 63,000 tons per day of sized, washed coal. The basic process involves high temperature (2800/sup 0/F to 3000/sup 0/F), high pressure (500 psig) gasification of pulverized coal in an oxygenblown gasifier to produce a syngas that must be cleaned, shifted to the proper hydrogencarbon ...

Beneficial use is the recycling or reuse of coal ash in lieu of disposal. For example, coal ash is an important ingredient in the manufacture of concrete and wallboard, and EPA supports the responsible use of coal ash in this manner. This final rule supports the responsible recycling of coal ash by distinguishing beneficial use from disposal.
