FOWA Model 1: Recycling of 100 pounds of waste asphalt.

Description of the basic unit:

FOWA Model 1 (Fuel Oil form Waste Asphalt Model 1) is designed for use by operators producing small volumes of waste. The reaction vessel is 24” diameter and height of 12” with a bottom drain. The drain pipe is connected to an Oil Water Separator through a ball valve. The ball valve controls the flow of oily water in the oil-water separator (OWS). The unit is manually operated though it can be made automatic if needed. The process is given below.

  1. Add 100 pounds of pulverized asphalt into the reaction vessel
  2. Spray 50 ml starter solvent (diesel) over the surface
  3. Immediately spray VaporRemed over the surface of the waste asphalt
  4. Free oil droplets are formed over the surface
  5. Add a spray of water from the top of the reaction vessel
  6. Once the top of the waste is covered shut off the water
  7. Oil begins to float on the water
  8. Open the ball valve to release the water to OWS
  9. Repeat multiple times till all the oil is collected
  10. The clean gravel is almost white for re-use

The process of recycling waste asphalt is environment friendly and it is now a source of revenue by sale of fuel and also clean aggregate.
