Pyrolysis plant
Pyrolysis plant can convert waste tire/plastic to fuel oil ,carbon black and steel wire by pyrolysis.
Feedstock processing: Depending on the plant size, the feedstock will be cleaned and shredded or crushed. In smaller plant, this may be done by hand, but in larger systems, mechanical shredding and crushing are used. Feedstock can be used without cleaning, but this increases the amount of char generated, and could affect the feed process for continuous systems.
Feedstock melt or extrusion: This only applies to larger systems using continuous operations. The shredded or crushed plastic is melted and extruded into shapes that can be handled by the continuous feed system of the plant. The melt cycle also serves to exclude oxygen from the pyroliser.
Load into the pyroliser: In smaller systems running on a batch process loading is done on a manual basis.
Pyrolisis: plastic is subjected to heat in an oxygen free environment, which depolymerises the plastic into a gaseous form. Contaminants and other items such as fillers are converted to char, or carbon black. The temperature of pyrolysis and the catalysts used will determine the output product. The plastic is pyrolysed at 370 to 420°C, and the pyrolysis gases are condensed in a two-stage condenser to produce a low-sulphur distillate. During start up, the pyrolysis furnaces are supplemented with either natural gas or liquefied petroleum gas (LPG), depending on availability. After the process has stabilised, the syngas produced is used to heat the pyroliser.
The vapour is converted into various fractions, including raw diesel, in the distillation column and the distillates then pass into the recovery tanks.
Many of the larger plants use the fuel produced to drive electrical generators which run the recycling plant Most pyrolysis plant are energy positive i.e. produce more energy or electricity than the required to run the plant. Surplus electricity is exported to the grid.
