The difference between the old refining system and the new system
In the new refining process, in order to reduce the production cost and increase the refining speed and reduce the cost price of the final product, in the refining process, instead of using traditional bach wise methods, the continuos method is used.
In this process, due to the use of composite towers, all feeds available in the market such as fuel oil, vacuum baton, slabs and other feeds can be used. These production units have the ability to produce any type of bitumen and are dedicated to the production and consumption of feed. And they are not special bitumen.
In the new refining process, due to the design and installation of explosion-proof valves, the risk of explosion and fire will be eliminated.
In the old process, the bitumen firing tower needed to absorb a lot of energy to refine and raise its temperature, which was produced by spraying fuel in the central pipe of the tower with high heat and for a long time.
This method first consumes a lot of fuel and causes a large amount of carbon dioxide, carbon monoxide and other environmental pollutants. In this method, the cost of energy consumption for production is very high, but in the new refining process to produce the heat required by the tower, this energy is not needed and it uses the heat of chemical reactions to raise the temperature and refine the bitumen.
In the units that work in the old way, basically no bitumen is produced in the cooking tower, but only the initial feed condensation operation is done. Unfortunately, the product made from this incorrect method of bitumen production is exposed to weak UV rays of the sun. is .
In the old refining process, vapors and aromatic compounds from the charcoal production process due to direct heat in the tanks and its reaction with oxygen cause the production of sulfur gas and are spread in the ambient air. But in the design of the new process, this defect has been eliminated.
In previous processes, the aeration system of the tower, due to the lack of calculation of air pressure, did not give any data to the person in charge of bitumen firing and the person in charge is unaware of the situation inside the tower, except for the temperature inside.
