HERTOS Pyrolysis Technologies

Is designed and developed from our engineering group. We are highly specialized in decomposition of organic and inorganic materials as part of a rapid and continuous pyrolysis process. Finally, the refining research and technology for pyrolysis by products is also part of the smaller, modular high performance systems rather than larger rigid complex designs.

Our mission is to roll out the now proven technology that has operated for several years with processing tires, plastic as well as other waste streams into profitable products.

HERTOS pyrolysis process works while our competitive advantage which is our simplicity and reliability. In today’s hi-tech economy complexity is the norm; however in evaluating many Pyrolysis systems and similar systems that have failed our design team has concluded that our focus MUST BE based on simplicity and reliability using modular technology depending on a fast execution avoiding massive engineering studies and projects. Simple modular design where each component has been tested a uniquely specified as integrated system components which will be described.

The particular project will include the individual components, specifications, details of the sources and type of the waste stream. The plant layout and the methodology to be followed by  the direct operation areas and the support functions  illustrating how the system is synchronized to cue up and flow the materials through the Pyrolysis function. Next, the power generation, distilling and sales functions are described and applied to a timeline view of the project with an associated sources and uses of funds.

The scale up plan for the facilities after the Bulgaria plant will provide the logic and methodology for adding multiple plants. This is a well thought time line that  is a separate yet crucial scale up model for the related supply chain management that is required to rapidly scale up the component manufacturing required building pyrolysis systems.

Finally, the operating company and the scale up of other facilities is discussed along with the capital structure and ownership structure.
HERTOS pyrolysis plants are designed to be very versatile with the capability to recycle various carbon containing waste:

  • used tires
  • plastic
  • medical waste
  • roofing materials
  • oil refining waste (oil slime)

This way we are not constrained by any shortages in a particular waste stream.

Our system is specifically designed with simple yet very demanding metallurgical tolerances to insure maximum uptime and maximum cash flow.

Pyrolysis (from Greek. pyr – fire, heat and lysis – decomposition) is a thermal decomposition of the organic compounds in the absence of oxygen.

The simple summary of the process

Raw material (waste) is loaded inside the container of heat-resistant material (retort). The retort is placed into the oven vessel. Raw material is heated by the heat transfer through the retort walls and the Pyrolysis process commences thermally decomposing the raw material forming a mixture of steam and gas and carbon residue. Steam gas mixture goes out of the retort through the pipeline, cooled, then it comes to the storage tank and then to the condensers where the gases are separated from the liquid. The liquid is collected in a storage tank; gas, partially or wholly is used to support the pyrolysis process, or burned to produce electric or used to heat greenhouses, offices and so on. At the end of the pyrolysis process the retort with carbon black must be unloaded from the oven and the other retort with raw material is placed into it.

Depending on the type of raw material used the fluctuations in the volumes of products received are possible.

Short Processing Overview

The most effectively is to operate two and more pyrolysis ovens together with using of the abundant gas of the first oven to heat the second one. At each period of time the ovens are at different stages of the process. The shift of the process phase between two ovens is chosen in such a way that the second oven passes the stage of maximum gassing at the time when the first oven has the greatest need in fuel. Thus there is no need in the additional solid-fuel, the emissions into the atmosphere are significantly reduced (gaseous fuel gives significantly fewer emissions per unit of energy and almost no soot particles); there is no need in gasholder for temporary storage of a gas.

The optimal temperature area of our patented technological process is 350-400 °C; the following products are obtained (used tires pyrolysis):

  • The liquid fraction (synthetic oil, pyrolysis oil) -36-45%
  • Pyrolysis gases to 12%
  • Carbon black up to 40%
  • Metal scrap 8%
  • Carbon black

After the process of pyrolysis they receive pyrolysis oil, metal scrap and carbon black.
