Technology and process

After a comparative analysis of more than a dozen used in the world of technology, we are fully convinced that the gasification technology Thermotec, which provides flameless processing the raw material, has a real significant advantages compared to other technologies competing companies.


Gasification is a process that converts carbonaceous minerals or organic materials into carbon monoxide, hydrogen and carbon dioxide. This is achieved by the interaction of the material at high temperatures (> 700 ° C), without combustion, a controlled amount of oxygen and / or steam. The resulting gas mixture called synthesis gas (syngas) and gas generator, which is itself a fuel. For example, the energy obtained from the gasification of biomass and combustion of the resultant gas is a renewable energy source; gasification of fossil materials – petroleum derivatives such as plastics, are not considered to be renewable energy source.

Gasification is a great opportunity to use energy in the future. Synthesis gas produced by gasification of the starting material can be purified relatively easily. Thus, unlike the direct combustion of coal (traditional approach), it further provides complete combustion.

By its purity purified synthesis gas may be compared to natural gas that can burn it in a more efficient gas turbine, and not in the boiler, which drives a steam turbine (or operated on CHP).

Synthesis gas produced in the gasification process can change its CO: combustible CO in the synthesis gas is converted to carbon dioxide (CO2), when water is used as a reagent. CO shift reaction also releases combustible hydrogen (H2), is equal in volume CO, which is transformed into CO2.

The concentration of CO2 (or even partial pressure of CO2), produced by the gasification of coal and the reaction transforming CO, is much higher than in coal combustion in air (which in most cases includes nitrogen).

The advantage of gasification

An advantage of gasification is that the use of synthesis gas is potentially more efficient than the direct burning of the fuel source, since it can be fired at higher temperatures or even in the fuel particles so that the upper limit thermodynamic efficiency, Carnot certain rule, is higher or do not apply. Syngas may be burned directly in a gas engine used for the production of methanol and hydrogen, or is transformed into a synthetic fuel with a Fischer-Tropsch process.

The gasification process may also begin with the use of biodegradable waste. In addition, when high temperature processes are separated corrosive elements, such as ash and potassium chloride, thereby producing a clean gas from impure fuel. Currently, the gasification of fossil fuels for electricity production is widely used on an industrial scale.


The technology developed by the company can process virtually any feedstock, due to the unique and innovative process of thermolysis.

Thermolysis – a chemical decomposition caused by heat. The decomposition temperature of the substance is the temperature at which a substance is chemically decomposed. Thermolysis word comes from the Greek words thérmē – “hot, hot” and lýsis – “separation”.

Thermolysis process to install Thermotec is adiabatic, the combined process based on thermo-chemical destruction of the starting material is carried out without the use of the boost pressure. It is based on applying advanced ideas, such as multi bidirectional production process gas optimal quantity and quality of produced synthesis gas produced during thermolysis coke.

 The entire process takes place in a non-flammable and environment in the absence of oxygen, which also characterizes the process as innovative.

How is the process


Brief description of the manufacturing process to install Thermotec


tehnologija1Proizvodstvenny process based on the thermolysis technology can be described as follows: the prepared and sorted raw materials (eg household waste) is loaded into a hopper. Then, from the hopper it is transported into the thermolysis. The temperature of the incoming raw material increases due to the direct heating kosvennnogo and using the produced synthesis gas. As a result of the evaporation and separates oxygen.

tehnologija2With feed screw conveyors (e.g., dry waste) is fed into a multistage thermolysis reactor apparatus for low-temperature carbonization at a temperature of 400 ° C to 950 ° C. Each reactor consists of two chambers nizkotemperaturnoh carbonized outer housing thermolysis device input and output chambers and burners . The reaction of the low-temperature carbonization produces synthesis gas, which then flows into the gas enrichment section, where it is cleaning (from minor impurities and byproducts). Carbonation at low temperatures and fumigation feedstock occur in both the low-temperature carbonization chambers at different temperatures.


Heating required for the coking process, by means of heaters disposed in the chamber on the outer body of the device thermolysis. Monitoring and control of reactors, as well as guarantee their safe operation are carried out through a number of measurement sensors and security system within the unified system of operational management. Gas supply system is protected from overpressure appropriate amount of measuring and control membranes. In the case of increased internal pressure or other emergency, the resulting gas is sent to the burner. In addition, for immediate interruption of the reaction of low-temperature carbonization unit is equipped with water-steam system discharges.

tehnologija4To reactor connected in series two screw assembly. In them there is a further thermal decomposition of raw coke and releasing syngas. Just as thermolysis reactor installation coking provided with heating body used for direct heating. The dry residue (coke and ash), after suitable cooling (using steam and water) is fed into sealed containers. After cooling, the ash and mineral particles are separated and recycled.


In the enrichment section of gas the synthesis gas passes through the scrubber, separators, storage tanks and pumps. Each reactor is connected to a scrubber – absorption of gas purification installation. Gas flows from the two lines are connected to and pass through the absorptive purification stages, where, during the circulation of the condensate is absorbed from the coke oven gas, and the gas is cooled. Issued olefins, aromatics, paraffins and other materials, as well as water and hot oil pumped circulators create systems activator. Upon contact with the activator harmful substances and lighter particles are removed during the washing cycle. As a result, depending on what substance is obtained, or the cracker in the separator installation is an additional washing with water. The required amount of the absorption system depends upon the composition of the feedstock.


tehnologija7In the processing of synthesis gas achieved complete condensation of aliphatic and aromatic compounds. The content of harmful impurities (eg., HCL) is reduced by neutralization with lime water. Using separators oil fatty media and water are separated. The wastewater is further purified with activated carbon, and subjected to biological cleaning, the available installation thermolysis. After that waste water can be released into the sewer system of industrial zone.

The waste in the process of thermolysis air is cleaned in the biological treatment. For the destruction of odor emissions caused by the exhaust gases from sewage and waste multistage drying process, it is removed from the working area through a piping system with integrated biological gaskets.

Installation for feeding waste water diverted from the water purification system for further use. The exhaust air is released into the atmosphere through the air valve. The organic waste is removed and cyclically loaded during thermolysis. Water circulation system designed for cleaning gas comprises cooling equipment connected to the coolant, which runs on air.

tehnologija8After passing all stages of purification process gas stream enters the storage facility. Gasholder serves for receiving and delaying the synthesis gas obtained during the thermolysis process, to provide power, to energize the burner and coker reactor and the gas supply to the consumer through a compressor station. The quality of the exhaust gas in the reactor is balanced by its reverse reaction. Containers of various sizes are used as buffers.

The protection system consists of a burner, which is, in case of emergency, a reliable output of the synthesis gas from the coking and gas storage facilities. Through connecting pipe fittings pass that, in the event of a power failure, the burner opens independently. To prevent an unexpected rise in pressure joints reactors and burners equipped with safety membranes.

tehnologija9In production area of ​​energy produced synthesis gas is converted into electrical energy (through cooperation “energy-heat”). The exhaust gases of the two compartments are mixed and output through the chimney. Thus, in accordance with the requirements made of emissions control, and monitoring. Most of the synthesis gas may be directed to a plant for the production of motor fuel for vehicles with small engines that provide high reliability of operation and will fully meet the demands of consumers.

When applying the technology thermolysis organic substances are divided into short chain hydrocarbons, thus reducing the content of iron oxide and oxides of other inorganic substances (eg., Oxides of sulfur).
