Abstract
A visit was made to the San Juan Cement Company (SIC-3241), Dorado, Puerto Rico to evaluate control methods for a storage and delivery system for hazardous wastes used in a demonstration project as a supplemental fuel for cofiring a cement kiln. Analysis of this material during the visit revealed the presence of methylene- chloride (75092), carbon-tetrachloride (56235), chloroform (67663), acetone (67641), hexane (110543), ethanol (64175), and ethyl-acetate (141786). Steel storage tanks were placed on an impermeable concrete slab surrounded by a sealed retaining wall. Steel piping with all welded joints carried the waste fuels from storage tanks to the kiln, where fuels were injected through a specially fabricated burner. Vapor emissions were suppressed by venting the displaced vapor through a recycle line. Exhaust gases from the kiln passed through a bag house type dust collector, and were vented to the atmosphere through a single stack. Half mask air purifying respirators were used when in the hazardous waste storage/delivery area. Neoprene gloves were used when performing tasks with potential skin contact. Hard hats, safety glasses and safety boots were all worn. The author concludes that the control methods used seemed effective in suppressing vapor emissions.
