Technological Process
Feed the scrap plastics or tires into the high temperature and normal pressure pyrolysis reactor directly without removing sediment, water, steel wire and other impurities, and then heat the raw materials and catalyst in the reactor. Through the pyrolysis process, we get the oil vapour. The vapour goes through the condenser and is liquefied to oil mixture. The vapour that can’t be liquefied in the normal pressure goes through gas system for burning the bottom of the reactor. The oil mixture having been liquefied enters fractionation processer for being burnt, and then get base fuel oil. After precipitation filtration and add various kinds of additive, the oil becomes qualified fuel oil.
1. Security
- Specific operating tech to deal with all the bug during the production.
- Hydroseal and Vacuum system will prevent exhaust gas from going back to condensers and reactor. Thus, unnecessary accident can be avoided.
- Equipped with thermometer, pressure gauge, safety valve and electric control system.
- Combustible gas can be purified in hydroseal before being burnt which prevents the dangers that exhaust gas (alkane class from C1 to C4) may causes.
- Waste gas burner can prevent over-pressure of the reactor.
- Equipped with safety device (alarm for over temperature and pressure, auto pressure releasing system, extra gas recycling system, fire fighting devices), which can prevent unnecessary accident and guarantee safety in production.
2. Environmental Protection
The treatment of the three exhausts in the production process:
a. Exhaust gas
By means of full combustion through water seal and gas nozzle, it can not only eliminate the exhaust gas pollution, but also sale a large number of fuel materials. In dust emission area, we adopts proprietary national patent products strong atomization dust desulfurization equipment and make the discharge of smoke and dust meet related standards of GB 13271—2001.
b. Exhaust liquid
In the treatment process of oil products, there will be waste water with weak acid (every one ton oil production generates about 50kg water, small volume and easy to dispose) generating. After neutralization by adding faintly alkaline liquor, the neutral waste water shall be harmless with three-grade filtration and be discharged into special evaporation processor to vapor (heat source is the flue residual heat of main processor).
c. Exhaust solid waste
The residue left from catalysis and split of waste plastic is carbon black, which accounts for about 10%-15% in the waste plastic weight. It can be used as raw material for industrial carbon black production, and also can be used as auxiliary fuel for power plant. We have special discharge technology to ensure environmental protection.
