Company Description

Pyrolysis is a thermochemical decomposition of organic material at elevated temperatures without the participation of oxygen. It involves the simultaneous change of chemical composition and physical phase, and is irreversible. The word is coined from the Greek-derived elements pyro "fire" and lysis "separating". Pyrolysis is a case of thermolysis, and is most commonly used for organic materials, being, therefore, one of the processes involved in charring. The pyrolysis of wood, which starts at 200–300 °C (390–570 °F), [1] occurs for example in fires where solid fuels are burning or when vegetation comes into contact with lava in volcanic eruptions. In general, pyrolysis of organic substances produces gas and liquid products and leaves a solid residue richer in carbon content, char. Extreme pyrolysis, which leaves mostly carbon as the residue, is calledcarbonization. The process is used heavily in the chemical industry, for example, to produce charcoal, activated carbon, methanol, and other chemicals from wood, to convert ethylene dichlorideinto vinyl chloride to make PVC, to produce coke from coal, to convert biomass into syngas and biochar, to turn waste into safely disposable substances, and for transforming medium-weight hydrocarbons from oil into lighter ones like gasoline. These specialized uses of pyrolysis may be called various names, such as dry distillation, destructive distillation, or cracking. Pyrolysis also plays an important role in several cooking procedures, such as baking, frying, grilling, and caramelizing. In addition, it is a tool of chemical analysis, for example, in mass spectrometry and in carbon-14 dating. Indeed, many important chemical substances, such as phosphorus and sulfuric acid, were first obtained by this process. Pyrolysis has been assumed to take place duringcatagenesis, the conversion of buried organic matter to fossil fuels. It is also the basis of pyrography. In their embalming process, the ancient Egyptians used a mixture of substances, including methanol, which they obtained from the pyrolysis of wood. Pyrolysis differs from other high-temperature processes like combustion and hydrolysis in that it usually does not involve reactions withoxygen, water, or any other reagents. In practice, it is not possible to achieve a completely oxygen-free atmosphere. Because some oxygen is present in any pyrolysis system, a small amount of oxidation occurs. The term has also been applied to the decomposition of organic material in the presence of superheated water or steam (hydrous pyrolysis), for example, in the steam cracking of oil. We mainly specialize in organic polymer pyrolysis, which can change waste plastic/rubber/oil into valuable items. We are specially focusing on Product Upgrade and Pollution Control. The systems operating on industrial scale convert waste materials (plastics, tyres, municipal solid waste, etc) back into useful and lucrative products without adverse emissions, discharges, or negative effects on the environment. Capacities: max 5-10 tpd single line. Core business activities: - Waste-to-energy: pyrolysis and gasification installations as a waste recycling facility and source of fuel/energy for other facilities (desalination, electricity generation, incineration, etc) - Thermal pyrolytic treatment of the decontaminated soil (oil, organics, etc) - Pyrolysis installation for toxic/medicine waste disposal. Product Description 1. Waste rubber/plastic shredding and feeding system The purpose of this system is to process the waste tires/plastic into the shreds less than 40x40mm with the rubber/plastic shredder (steel wire is cut together with the rubber shreds). 2. Heating system The purpose of this system is to provide the material inside the continuous reactor with the adequate heat for low temperature pyrolysis and cracking reaction and realize waste heat utilization, rapid and accurate temperature control and adjustment. 3. Continuous pyrolysis system Its purpose is to send the rubber/plastic shreds and catalyst together into the feeding machine via the lifting conveyer and then continuously send them into the reactor for heating via the feeding machine, after absorbing enough heat, the material low temperature pyrolysis and cracking reaction converting the rubber into a solid state(raw carbon black and steel wire) and a gas state (oil gas) product; it can realize continuous feeding, oil gas output and leftover discharging (raw carbon black and steel wire). 4. Oil separation and cooling system Purpose of the oil separator is to roughly separate the component of the pyrolysis oil gas into light oil component and heavy oil component. Purpose of the cooling system is to cool down the oil gas of light oil component and heavy oil component into liquid oil and combustible gas. 5. Combustible gas scrubbing system Its purpose is to scrub the combustible gas by making the combustible gas fully contact and react with the clarifying solution to eliminate the harmful component of the combustible gas, such as sulfureted hydrogen, mercaptan. The scrubbed combustible gas is used for heating system. 6. Gas purification system Its purpose is to cool and purify the surplus gas after cycling heating for pyrolysis with the gas purification system to make the content of sulfur dioxide, sulfur trioxide, nitrogen oxide, dust granule and other harmful substances meet the emission standard of the domestic relative industry. 7. Electric control System The purpose of this system is to centralized control the electric equipment of the whole production line by employing various of modern instrument and meters with characters such aseasy operation, object monitoring to ensure a reliable running of the line. 8. Raw carbon black processing system The purpose of this system is to continuously send the solid product (raw carbon) from the waste rubber pyrolysis reaction into the carbon black processing system to get the finished carbon balck.
