Installation recycling polymers by pyrolysis

The installation can be used for processing of various waste of industrial rubber and polymers, to generate liquid and solid pyrolysis products. Liquid pyrolysis products are very similar to the oil-products in quality and can be used as refer to the synthetic fuel for e.g. power generation.


Description

Mobile carbonization equipment "EKKO" are designed for utilization of hydrocarbon-containing waste by pyrolysis to obtain useful products in demand on the market - fuel, pyrolysis gas, carbon black.

The equipment allows carbonization of more than 200 types and groups of waste such as: used car tires, rubber waste, various polymers, fabric waste, oil sludge and other carbon-containing waste.

The designated area of the unit and the output of commercial products

Destruction of newly formed and stale waste, elimination of dumps and landfills, processing of raw materials into marketable products:

  1. liquid fuel,
  2. semi-coke,
  3. Bio-char
  4. synthesis gas

The output and composition of commercial products depends mainly on the method of conducting the process and the composition of the raw materials subjected to carbonization, for polymers and rubber goods it is usually:

  1. Liquid fractions of hydrocarbons = 30-40%
  2. Carbon residue = 30-35%
  3. Synthesis gas = 10-15%

Liquid fractions of hydrocarbons (liquid fuel)

Similar to boiler fuel for combustion in kilns to generate heat and electricity. It is possible to separate into fractions and use them as raw materials for deeper recycling to obtain motor fuels.

The composition of liquid fuel fractions depends on the type of processed raw materials, for example, from:

  • Rubber wastes contain mainly heavy oil fractions: bitumen, fuel oil, diesel fractions and to a lesser extent contain: gasoline, solvent fractions and kerosene
  • polymers (PP, PE, PS) contain mainly light petroleum fractions: gasoline, diesel, kerosene and alcohol fractions

Consumers: Enterprises operating liquid fuel burners (asphalt factories, chemical, metallurgical, glass-blowing enterprises, housing and communal services, etc.);

Carbon residue

From synthetic raw materials such as polymers and industrial rubber goods, the following types of carbon residue are separated:

  • Semi-coke - used as a solid fuel for combustion in kilns, with or without preliminary briquetting. The calorific value of this type of fuel is> 6,500 Kcal.
  • Carbon black – is obtained at a high final temperature of carbonization of the carbonaceous residue, as well as the subsequent separation of impurities and further grinding. Carbon black is widely used in the national economy.
  • Consumers: Manufacturers of building materials, chemical production, production of activated carbons, sorbents, fuel additives.
  • Bio-Char obtained during the recycling of organic and all types of plant waste, is used in agriculture to restore soil fertility and animal breeding as a bait for animals.

Synthesis gas

Жидкая фракция

It is a non-condensable residue of pyrolysis gas released as a result of carbonization (pyrolysis) of raw materials. It is used to support the process in the carbonization unit, it is also possible to obtain electrical energy using gas-methane electric generators. Usually used for the own needs of the enterprise.

Technical description

Technological process

Raw materials are loaded into raw material containers, after which they are hermetically closed. Containers with raw materials for pyrolysis are loaded into the chambers of the carbonization equipment.

Initially, the carbonization equipment is heated using additional fuel: firewood or charcoal, products of our own production can also be used: carbon residue (semi coke), liquid fuel fraction, pyrolysis gas. After the equipment reaches the operational mode, depending on the parameters of the raw material (2-6 hours), additional fuel is not required, the gas burner is started, which operates on the non-condensable residue of pyrolysis products.

Carbonization process – includes two reactions, exothermic and endothermic. Exothermic reaction occurs with the release of heat, therefore, excess heat from the reaction is used for the endothermic reaction in the second chamber takes place.

The duration of the pyrolysis process, depending on the raw material used, is from 6 up to 12 hours. At the end of the process, as evidenced by the Control and measurement devices readings and the end of gas releasing, the pyrolysis equipment is opened and the trolley is taking off using an electric winch, which is sealed and installed on the platform for cooling.

In turn, the trolley loaded with a new batch of raw materials is installed in the vacated chamber, after which the process is repeated. The delivery set for one pyrolysis equipment is provided with 4-6 trolleys, which allows equipment operate continuously, taking into account time for cooling, loading of raw materials and unloading of carbon residue from the trolley.

After complete cooling in the trolley (10-16 hours), the carbon residue can be taken off from the trolley.

The products obtained as a result of processing are subject to further processing in order to generate additional profit.
