Scope of liquid fuel in this compendium:
- Liquid fuel within this compendium is defined as plastic-derived liquid hydrocarbons at a normal temperature and pressure. Only several types of thermoplastics undergo thermal decomposition to yield liquid hydrocarbons used as liquid fuel. PE, PP, and PS, are preferred for the feedstock of the production of liquid hydrocarbons. The addition of thermosetting plastics, wood, and paper to feedstock leads to the formation of carbonous substance. It lowers the rate and yields of liquid products.
- Depending on the components of the waste plastic being used as feedstock for fuel production, the resulting liquid fuel may contain other contaminants such as amines, alcohols, waxy hydrocarbons and some inorganic substances. Contamination of nitrogen, sulfur and halogens gives flu gas pollution. Unexpected contamination and high water contents may lower the product yields and shorten the lifetime of a reactor for pyrolysis Liquid fuel users require petroleum substitutes such as gasoline, diesel fuel and heavy oil. In these fuels, various additives are often mixed with the liquid hydrocarbons to improve the burner or the engine performance.
- The fuel properties such as viscosity and ash content should conform to the specifications of the fuel userâ€™s burners or engines. No additives would be needed for fuel used in a boiler. A JIS technical specification was proposed for pyrolytic oil generated from waste plastic for use as boiler and diesel generator fuel (TS Z 0025:2004).
- Skillful operators and a well-equipped facility are required due to the formation of highly flammable liquids and gases.
- The production method for the conversion of plastics to liquid fuel is based on the pyrolysis of the plastics and the condensation of the resulting hydrocarbons. Pyrolysis refers to the thermal decomposition of the matter under an inert gas like nitrogen.
- For the production process of liquid fuel, the plastics that are suitable for the conversion are introduced into a reactor where they will decompose at 450 to 550 ï‚°C. Depending on the pyrolysis conditions and the type of plastic used, carbonous matter gradually develops as a deposit on the inner surface of the reactor. After pyrolysis, this deposit should be removed from the reactor in order to maintain the heat conduction efficiency of the reactor.
- The resulting oil (mixture of liquid hydrocarbons) is continuously distilled once the waste plastics inside the reactor are decomposed enough to evaporate upon reaching the reaction temperature. The evaporated oil is further cracked with a catalyst. The boiling point of the produced oil is controlled by the operation conditions of the reactor, the cracker and the condenser.
- In some cases, distillation equipment is installed to perform fractional distillation to meet the userâ€™s requirements. After the resulting hydrocarbons are distilled from the reactor, some hydrocarbons with high
- boiling points such as diesel, kerosene and gasoline are condensed in a water-cooled condenser. The liquid hydrocarbons are then collected in a storage tank through a receiver tank. Gaseous hydrocarbons such as methane, ethane, propylene and butanes cannot be condensed and are therefore incinerated in a flare stack.
- This flare stack is required when the volume of the exhaust gas emitted from the reactor is expected to be large. There may be variations in the feeding methods used depending on the characteristics of the waste plastic. The easiest way is to simply introduce the waste plastics into the reactor without any pretreatment. Soft plastics such as films and bags are often treated with a shredder and a melter (hot melt extruder) in order to feed them into the reactor because otherwise they would occupy a large volume of the reactor.
- There are also different types of reactors and heating equipment. Both kiln-type and
- screw-type reactors have been proposed, while induction heating by electric power has been developed as an alternative to using a burner.
- Due to the formation of carbonous matter in the reactor, which acts as a heat insulator, in some tank reactors the stirrer is used to remove the carbonous matter rather than for stirring. After the liquid product of the pyrolysis is distilled, the carbonous matter is taken out either with a vacuum cleaner or in some cases reactors are equipped with a screw conveyor at the bottom of the tank reactor to remove the carbonous matter.
- Operators should understand the relationship between the amount and composition of the waste plastics as well as the operating conditions.
- Energy consumption and plant costs relative to the plastic treatment capacity are the typical criteria for evaluating the plant performance. Operating skill and safety considerations are important in this type of chemical conversion due to the highly flammable liquid fuels which are formed.
