Using ERVO technology. Processing equipment
The technology of processing organic high-molecular waste and materials (plastics, solid alternative fuel TAT, sewage sludge) by thermal depolymerization is not new from the point of view of the physicochemical process – equipment for thermal processing of raw materials was used as early as 1938 in Germany and England.
However, continuous technology, as opposed to batch loading, is new in Europe, and especially in the Czech Republic.
The ERVO 5 device is protected by a patent application, as is the method of continuous multicyclic depolymerization of organic substances.
The main product in the processing process is carbon coke (Bio-Char), a gas, a liquid petroleum product containing about 70% aromatic hydrocarbons. The technology has no significant environmental impact and does not require analysis in accordance with the Environmental Impact Assessment Act.
ERVO technology allows converting almost all organic and high molecular weight (polymer) structures into gas, liquid fraction and solid residue. ERVO technology is based on thermal decomposition and reactive distillation. ERVO technology is a continuous (continuous) technology.
The process gas obtained during the waste treatment process is used as fuel, for heating the ERVO reactor, for processing as a raw material for obtaining various gases (hydrogen, methane, carbon monoxide, ethanol). The liquid fraction is used as fuel or as a raw material for the petrochemical industry – aromatic hydrocarbons. The carbon residue is used as a raw material for the production of rubber, various filters, absorbent materials, paints, carbon black products, as a fertilizer for the soil or as a fuel for burning in a furnace, if necessary.
Possible processing:
- used car tires,
- various plastics
- solid waste and other organic waste.
Additional information on the possible recycling of various wastes
- Paper and pulp waste
- Chlorinated and other plastics
- Expired agricultural fertilizers and poisons.
- Agricultural waste (possible disposal of small poultry, no prior freezing required)
- Medical waste (MHW), including infected waste (dressing material, syringes, packaging, gauze bandages, etc.)
- Rubber and technical waste (RTW)
- Woodworking waste and logging residues
- Bituminous waste
- Municipal Solid Waste (MSW) — (mixed municipal waste)
- Food waste (FW)
- Solid industrial waste (SWW)
- Waste cooking and industrial oils, oil-contaminated soils.
Processing of peat, silt deposits and oil sludge is also possible.
Waste processing technology by pyrolysis.
The proposed production cycle technology – multi-stage depolymerization and reforming of waste by low-temperature pyrolysis – consists in heating the waste inside the reactor without access to air and contact with the environment. Such heating leads to molecular decomposition and reforming, resulting in the following products:
- Pyrolysis fuel.
- Flammable gas.
- Carbon residue.
When recycling tires, additional metal cord is used.
The quantitative composition of fractions obtained during waste processing depends on their morphology:
- Liquid pyrolysis fuel 35 ÷ 42%.
- Carbon combustible residue up to 38÷45%.
- Flammable gas up to 18%.
- Metal residues up to 5%.
This technology implements pre-designed thermal regimes to obtain a certain steam-gas mixture in the reactor, the heat to which is supplied through its walls. The reactor operates continuously without stopping, according to pre-designed programs that control the temperature in certain places of the equipment and the volume of raw materials being loaded.
The basic equipment set consists of:
- pyrolysis reactor;
- capacitors,
- tanks for gas and liquid fraction,
- waste reception and loading unit,
- unit for neutralizing harmful impurities and preparing raw materials for loading into the reactor,
- carbon residue unloading unit, with cooling device, with bunker for collecting and accumulating carbon residue,
- heat distribution systems,
- liquid fractions purification and filtration unit.
