FAQs About Pyrolysis Plant

Waste tires: Big car tires, truck tires, OTR tires, motorcycle tires, bicycle tires, etc.;

Waste plastics: PP, PE, PS, ABS, etc. (except PET and PVC);

Waste rubber: Rubber cable sheath, rubber soles and all the other kinds of rubber sheets or carpets;

Oil sludge: floor oil sludge, tank bottom oil sludge, refinery oil sludge, crude oil sludge, petroleum sludge, engine oil sludge, drilling cuttings etc.

Yes. The tires with normal diameter of less than 1200mm can directly enter the pyrolysis reactor, while the tires that larger than 1200mm need to be shredded before pyrolysis.

Better not. It is recommended to handle the plastics and the tires separately. The pyrolysis temperatures of the two materials are different, so it will affect the process. The plastic pyrolysis process is prone to blockage of the system by wax oil, so the catalytic tower system is equipped as needed; while the tire pyrolysis process does not have the above problems. In addition, the carbon black from waste tire pyrolysis can be further processed and utilized, but the plastic residues are general industrial solid wastes. After being mixed with plastic and pyrolyzed, the residue will reduce the utilization value of tire pyrolysis carbon black. So it is recommended to classify separately and treat by quality to improve the added value of products.

Yes, totally. Different types of plastics have different oil yields and quality.

For manual feeding and hydraulic feeding, tire diameter and plastic bales are required to be smaller than 1.2m and can be fed directly;

For screw feeding, tire ≤5cm, plastic ≤5cm, moisture content below 10%.

Note: We will get different finished products from different raw materials. The proportions of the final products also vary according to the raw materials.

The oil yield of different raw materials is very different. You can refer to the picture below for a general understanding. If you want to know the specific oil yield, you can contact us to send samples for testing.

Yes. After further distillation, the pyrolysis oil can be mixed with conventional diesel to be used as fuel for low-speed vehicles.

Yes, it can be used as special generator fuel.

No. The waste water in the water seal and spray tower can be evaporated at high temperature in the discharge chamber and furnace, and the residual oil in the residual oil tank can be directly re-entered into the main reactor for re-pyrolysis or stratified and directly mixed into the pyrolysis oil. The flue gas emission will be discharged up to the standard after exhaust gas treatment, and there will be no waste particulate matter discharged.

Yes, we have SGS reports for tire and plastic pyrolysis oil. Please contact us if you need more details.

1. The condensation area of the combustible gas condenser;

2. The water volume and water temperature of the circulating water;

3. Heating rate and temperature control.

The normal operating temperature for plastic and tire pyrolysis is between 280-350 degrees, generally not higher than 400 degrees. Overall, the temperature for plastic pyrolysis is a little higher than tire pyrolysis.

The tire pyrolysis oil starts generating at 180℃, and the maximum oil generates at 280-350℃. the working pressure does not exceed 0.02Mpa.

Natural gas, diesel, heavy oil are all available. Consumption depends on the specific model.

Similar chlorine and oxygen-containing plastics such as PVC and PET are not recommended to be treated; the feeding method is recommended to be packaged; the condenser is recommended to be 3-in-1 box-type condensation, and also equipped with a pyrolysis catalyst tower, special catalyst and catalyst regeneration system.

3-4 months. Or determine the frequency of cleaning based on actual usage.

1.The temperature of the main reactor increases and the temperature of the steam drum decreases;

2.The oil output is reduced and the oil is dark brown.

1. Enter the main reactor and then react;

2. Connect the water pipe to the exhaust combustion chamber and add a nozzle to burn.

The working pressure of batch pyrolysis reactor is 2-10kPa. The maximum pressure in the reactor is 20kPa.

The amount of exhaust gas is different according to the selection of model. The exhaust gas is mainly composed of two parts, most of which are produced by fuel combustion and process of heating the reactor, and small part is produced by the direct burning of excess pyrolysis gas. The exhaust gas mainly contains sulfur compounds, nitrogen oxides, dust, carbon monoxide and carbon dioxide, etc.

There are many European customers who are running the plant and the emissions meet the local standards.

Yes, it can reach the emission standard. The high-temperature flue gas is first treated by condensation and cooling in the flue, washed with water to remove oil and dust, and then goes through desulfurization tower, denitrification tower, dust removal, activated carbon adsorption, and finally the flue gas that meets the standard is discharged. We have many European success stories to meet European emission standards.

No. Just 100% operate the plant as the operation manual guides (will provide after making the deal) and the engineers of Beston Group will be responsible for training your workers how to operate the plant correctly and how to maintain it. We are here to help at any time.

Generally not. It depends on what kind of fuels you want to choose. Generally, if you’d like to process 1 ton feedstock, the estimated consumption of each kind of fuel is,

Coal: 85-90 KG;

Natural Gas: 70-80 m;

Diesel: 55-65 KG;

LPG: 50-55 KG.

Don’t forget that Beston has combustible gas recycling design for the pyrolysis plant. You can fully take use of the combustible gas generated from the pyrolysis process to heat the reactor.

Waste plastic treatment adopts gas-phase catalytic pyrolysis technology. It solves the technical problem of clogging the pipeline with wax oil and ensure the continuous and stable operation of the equipment. At the same time, it is helpful to improve the yield and quality of pyrolysis oil.

Batch type: feeding 3h + pyrolysis 11h + cooling down 7h + discharging 3h, about 24 hours per batch;

Semi-continuous: feeding 1.5h + pyrolysis 8h + cooling down 2h + discharging 2h, feeding again 1.5h + pyrolysis 6h + cooling down 2h+ discharging 2h, about 3 days every two batches;

Fully continuous: continuous feeding and discharging + pyrolysis 2h, running 24 days per month.

Keep sufficient safety distance between the reactor and the oil tank;

No sewage discharge; the heat exchange water source of the condenser is separated from the oil and gas. And water source does not directly contact with the oil and gas; The water inside the water seal can also be discharged into the combustion chamber when the fuel is burned to provide heat for the reactor;

The excess non-condensable combustible gas has a special exhaust combustion chamber, which will not be directly discharged into the air;

The exhaust gas reaches the EU emission standard after being treated by the de-dusting system.

Firstly, we do not provide electric heating system. Secondly, as far as we know, the cost of electric heating systems is very high. Thirdly, the power consumption per hour is huge. Taking BLJ-16 equipment as an example, it needs to consume about 1000kw per hour. Fourthly, the heat loss of electric heating is relatively large.

1.The structure of BLJ-3 model is compact and space-saving, which is convenient for transportation. As the skid-mounted type adopts intensive layout and compact layout, the land occupation can be greatly reduced, which is of great significance to the oil and gas industry that occupies a large amount of land;

2.It is convenient for demolition and movement. The skid-mounted device has the characteristics of demolition and relocation, and is especially suitable for installations in the oil and gas industry, which can avoid blind construction of factories and installations;

3.Indoor work. Most of the work is done in the manufacturing factory, and the on-site installation only requires the installation of the skid to the foundation, the connection of the inlet and outlet pipelines, and the wiring of some electrical instruments, which greatly reduces the on-site workload and installation time.

Yes.

Semi-continuous pyrolysis equipment is actually batch equipment plus automatic feeding (spiral) and three water-cooled slag dischargers. The tire needs to be pre-treated to the state of rubber powder in advance. Be careful not to have steel wire in it, otherwise the slag outlet will be blocked. Secondly, the three water-cooled slag production can basically achieve carbon black production in two hours. The normal cooling situation takes seven hours, saving five hours.
