C C GAS SYSTEMS, LLC 50 MMBTU Hazardous Waste Incinerator
GENERAL OVERVIEW The plant consists of the following items supplied by ,C C GAS SYSTEMS, LLC • • Tank farm consisting of five (5) each high BTU storage tanks c/w steam coils and five (5) each low BTU storage tanks w/o steam coils. In addition to the above tanks, future expansion has been allowed for four (4) more tanks, two (2) high BTU and two (2) low BTU tanks. • Each tank is blanketed with 45 psig of nitrogen, and connected to a scrubber system consisting of a condenser to collect the gases as a liquid and return them to the feed stream and a charcoal absorber to scrub the gases prior to releasing them to the atmosphere. • Incinerator train consisting of the following, feed system, rotary kiln & afterburner, flue gas cooler, spray dryer, baghouses, quench tower, cyclone separator, I.D. fan, exhaust stack and control unit. • Additional appurtenances will be required to make the plant a complete operating facility. • Optional equipment to utilize the steam from the flue gas cooler can be purchased at additional cost! (i.e.: desalination plant)

WASTE STREAMS The plant was designed to handle five (5) categories of waste streams: • High BTU Liquids (LHV = 18,400 BTU/LB) • Low BTU Liquids (SP.GR. of .69 to 1.36) • Solids (Dirt and Rock) 100 to 120 LB/Cu. Ft. • Reactive Wastes • Drum Wastes
WASTE STREAMS NOT ACCEPTABLE • Volatile metals • Radioactive materials • Explosive materials • Significant arsenic containing compounds • PCB’s and Dioxins (w/o modifications) • Waste Containing Chlorine in excess of 10.6% wt. (w/o modifications) • Municipal Waste (Capable, not efficient) • Infectious Waste • Asbestos Materials
UTILITIES NOT PROVIDED • Electricity • Water (Potable) • Compressed Air • Natural Gas • Boiler Feed Water • Nitrogen (N 2 ) • Carbon Dioxide (CO 2 ) • Caustic Soda (NaOH) (50% solution with H 2 O) • Water Disposal
BEST AVAILABLE EMISSION CONTROL TECHNOLOGY (BACT) BACT for this plant is: • At least 99% of the chlorine in the feed will be removed from the flue gas. • More than 95% of the sulfur dioxide in the flue gas will be removed. • Particulate matter will be reduced to 0.02 grains/dscf of the flue gas corrected to 7% oxygen. • Nitrogen oxide emissions will average less than 0.3 LBS/Million BTU heat input.
GENERAL COMMENT • The original design specified a 99.99 (minimum) destruction of the hydrocarbons in the waste feed. • The Flue Gas Cooler produces steam at a rate of 34,000 lbs./hr., 460 PSIG, and 650 F. The most efficient use of this steam would be a desalination plant, which should produce around one (1) MMGPD of potable water.
