Solution for Non degradable Plastic waste

As we know, black pollution and white pollution are a headache problem commonly facing by each area of the world. At the same time, oil resources are decreasing every day. But is there a way that can effectively solve this problem?

Thermo catalytic depolymerisation (TCD) or Pyrolysis are a common proven technique used to convert non-degradable polymer (NDP) waste into energy, in the form of solid, liquid and gaseous fuels. TCD is the thermal degradation of NDP waste at different temperatures to produced liquid oil. Pyrolysis is the chemical decomposition of condensed organic substances by heating. The word is coined from the Greek derived elements pyro “fire” and lysis “decomposition”.

Chemical recycling is an attractive way to address the explosive growth of non-degradable polymer (NDP) waste such as plastic/tyre waste and disposal problems. Thermo catalytic depolymerisation (TCD) is a chemical recycling process that can convert NDP waste into high quality oil (Poly-Oil), which can then be utilised as biofuel / industrial fuel in heavy internal combustion engines for power and heat generation.

The produced TCD poly-oils were analysed and found to have similar properties to diesel fuel. The pyrolysis oil produced lower NOX, UHC, CO and CO2 emissions than the diesel emissions.

Process Flow Scheme

Alterna Foss is maturing waste-to-energy technologies for chemical recycling of non-biodegradable polymer (NDP) waste including the toughest and dirtiest plastics including municipal solid waste segregated plastics and multilayer packaging. Figure 1 shows the process flow chart of AlternaFoss Pyrolysis Technology

Process Description

Polymer waste is stored in a raw material storage facility. This raw material is then conditioned and conveyed/load to (2) airlock feeding system which feeds the raw material into the (3) Pyrolysis reactor in absence of oxygen. Pyrolysis reactor converts non-biodegradable polymer waste into pyrolysis fluid/vapor, hydrocarbon gas and carbon black powder. (4) Carbon black powder is cooled and transferred to carbon black silo then either packed into bags or can be further processed as carbon black briquettes (6) through briquetting process system (5). (7) The mixture of pyrolysis fluid vapor and hydrocarbon gas exits pyrolysis reactor and is subjected to (8) fractional condensation so as to get (10) separate fractions of (9) hydrocarbon gas (11) pyrolysis wax and ‘Waste Plastic Oil (WPO) + Moisture’. Hydrocarbon gas is subjected to (12) high-temperature combustion and the produced hydrocarbon gas recycled as fuel gas to the pyrolysis reactor. The excess gas can be utilized as fuel gas for energy oriented other process to recover heat. The opportunities to utilize the excess gas will evaluated and implemented in future. Post high-temperature combustion, the exhaust gases are subjected to ‘waste heat recovery and scrubbing to control emission’ and cleaned flue gases will be vented through (13) exhaust pipe to chimney to safe location. (11) Pyrolysis wax is either subjected to (12) high-temperature combustion or opportunity to refine into (A) base oil for grease manufacturing in future. (A) The base oil can be then converted into (A) lubricating grease and oils. The mixture of ‘Waste Plastic Oil (WPO) + Moisture’ is passed through (14) oil-water separator to separate (15) the Waste Plastic Oil (WPO) and Oily Wastewater/ oily sludge (16) which goes back to the pyrolysis reactor along with the raw material. (15) Waste Plastic Oil (WPO) can be sold as it is in the market as a liquid fuel to be used in industrial burners. Otherwise, (15) Waste Plastic Oil (WPO) is either burned in slow-speed engines to produce electricity or is (B) refined into petroleum products like (Heavy Fuel Oil (D), (C) Diesel and Base Oil (E).
