Equipment safety: 
In the production process, the noncondensated gas is mainly composed of alkanes from C1 to C4. It is very dangerous to burn these noncondensated gases directly. Before burning, these gases will pass the safety of water sealing device first. Then pass gas burner. These two steps make sure safe production.
There is an anti-blockage device installed on oil refining equipment.
In addition, there is a pressure gage, alertor and safety valve installed in this equipment. Normally, this equipment works in negative pressure condition. In case of blockage and pressure, the alertor will work. If the worker doesn’t hear the alarm or the worker is not at work. The safety valve will work to reduce pressure, which insures safe production. Workers should operate according to correct regulations. Check often if pressure gage, alertor and safety valve work normally. While the equipment is running, worker in charge shouldn’t leave causally, not even sleep. Stay alert to guarantee safe production.
Environmental protection of oil refining equipment
Disposal to three wastes produced in the production process
1. Waste gas
Owing to the safety device of water sealing and full combustion of gas burner, waste gas gets eliminated and a great amount of fuels gets saved. Water impact spray desulfurization and dust removal device is used for disposal flue gas and dust. The emission of flue gas and dust can meet GB3271-2001 boiler air pollutant emission standards.
2. Waste liquor
In the process of oil disposal, some weak acid waste water will be produced (about 50-kg waste water will be produced while one-ton oil; small amount; easy to dispose). By adding weak alkaline, neutral wastewater will be processed by three-class filtration. After the aim of harmlessness is achieved, waste water will be discharged into a special evaporation processor (residual heat of flue gas of main processor is used as heat source.) for evaporation.
3. Waste solid
after being catalyzed and decomposed, the residual slag of waste tyres is carbon black. There is no waste solid.

12. Spray dust removal system
13. Electricity distribution cabinet;
14. Cooling water tower
15. High temperature oil pump
16. Oil pump
17. Water pump
Features of equipment: 
1. This device adopts pyrolysis furnace developed by our compnay (patent number: ZL 2012 1 0206913.X). this pyrolysis furnace can be applied to cracking used tyres, used plastics, usd rubber and used acrylic;
2. the whole equipment adopts multifunctional separator developed by our company in the running process (patent number: ZL 2014 2 0467359.5) to eliminate the solid particle impurity and liquid drop; then the aim to separate gas, solid and liquid can be achieved, which can guarantees the normal running of pipelines and equipment;
3. The whole device adopts static and dynamic seal system developed by our company (patent number: ZL 2012 2 0254180.2/ZL 2013 1 0443212.2). It is mainly used for the seal connection between static equipment and dynamic equipment. This seal equipment holds advantages of good plasticity, high intensity and easy maintenance. It can also play a compensating role for thermal expansion caused by temperature change. It can effectively reduce gas leak and damping between static and dynamic equipment.
4. The whole device adopts efficient self-cleaning condensator developed by our company (patent number: ZL 2013 2 0397822.9). It is a kind of energy-saving equipment which can realize heat transfer in two or more kinds of fluids. It is a kind of equipment which can thermal transferred from fluid with higher temperature to fluid with lower temperature. Then the temperature of fluid can reach to requested temperature and meet need of process conditions. Meanwhile, it is a kind of main equipment which can improve the utilization efficiency of heat energy. This condensator holds many advantages such as good effect, compact structure, less blockage, less flow resistance and easy to clean. These features prevent the materials condensation on pipe wall and avoid blockage.
5. The whole device adopts non-condensable gas back combustion device developed by our company (patent number: ZL 2012 2 0254119.8). There are some combustible gases which can not be condensated under normal atmospheric and normal temperature while the equipment is running. These gases will be burnt at the bottom of pyrolysis main furnace in waste gas back combustion system. Then, a great amount of thermal energy will be produced, which not only avoids pollution, but also saves fuels.
6. The noise produced in the operation process is not over 65 db. There is no smoke produced in the process.
7. There is a two-way water impact cyclone dust collecting system installed in flue dust removal system, which makes sure that the emission of flue gas meets national standard.
