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
• perating 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 (N2)
• Carbon Dioxide (CO2)
• Caustic Soda (NaOH) (50% solution with H2O)
• 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
• f 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.
