INTENDED USE:  Pyrolytic thermal decomposition of hydrocarbon waste with the recovery of pyrolysis gas, liquid fuel, and dry residue (carbon black).

WASTE TYPES: solid and liquid non-halogenous organic waste such as:

—        Plastics, tires, rubber, polypropylenes,

—        Oil sludge, oil-contaminated soils, drilling sludge and coal,

—        Waste oils, tar, bitumen, kerosene, any type of solvents,

—        Fuel oil residue, lubricating and heavy oils.

The process is based on low-temperature pyrolysis principle, involving the use of heat to thermally decompose hydrocarbon-based material in the condition of oxygen deficit.

Usage of the product derived from hydrocarbon-based raw materials:

  • Dry residue is used as asphalt filler, in soil reclamation, construction or in production of coal bricks
  • Heat of the process is recovered and used locally*
  • Pyrolysis oil is used as:

—  low grade fuel in boiler units
—  fuel of higher quality, such as diesel**

  • Syngas is used for the heating in the process

Usage of the product derived from brine-based raw materials:

  • Distilled water is used as:

— drilling solution preparation
— drinking water  ***

  • Dry residue is used as asphalt filler and concrete additives
  • Heat of the process is recovered and used locally*

* With an optional heat-exchanger (recuperator)

** With an optional rectification column

*** With an optional purification and mineralization systems

TDP-1 PROCESS DESCRIPTION:

1. Feedstock is loading into pyrolysis reactor through wide loading door, where combined gas-liquid burner without oxygen access heats it and the process of thermal decomposition starts.

2. Fuel is self-fed to the burner. The boiler fuel or diesel oil is used for the system’s start up only. After process stabilizing the burner is switched to the pyrolytic gas.

3. Vapour and gas mix from pyrolysis chamber is fed to the condensation system through gas filter.

4. Air is fanned to the filter jacket for cooling the mixture. Condensate is drained through bottom valve to the drum.

5. The further cooling of the mixture is carried out in the heat exchanger by recirculation.

6. From heat exchanger the product is fed to the gas-liquid separator where flows are separated.

=> PYROLYSIS OIL is directed to the storage tank;

=> SYNGAS is directed to the burner through hydroseal to satisfy system’s energy needs.

7. SOLID RESIDUE is discharged by tray through wide loading door.
