DÉGAZAGE CUVE À FIOULE ÎLE DE FRANCE when translated means degassing of oil tank in France. Degassing is a technique of separating the dissolved gasses from the liquid. It is also known as degasification.
What is the use of Degassing in DÉGAZAGE CUVE À FIOULE ÎLE DE FRANCE:
In the DEGASING OF OIL TANK IN FRANCE (DÉGAZAGE CUVE À FIOULE ÎLE DE FRANCE) process, the liquid in the oil tank has many dissolved gases. When certain gases mix with some liquid a chemical reaction occurs, which may make the resultant liquid very harmful. Therefore, the degasification process is carried out on the liquid before releasing it from the oil tank. It will ensure that the liquid released from the oil tank is non-toxic and not harmful to the environment.
DÉGAZAGE CUVE À FIOULE ÎLE DE FRANCE: Different ways used to degasify a liquid
Reducing the Pressure:
The gasses usually dissolve at high pressures, by reducing the pressure of the liquid the gasses can be separated from the liquid. This process is performed in the vacuum chambers, specialised vacuum chambers known as vacuum degassers are used in this process.
Besides, continuous stirring increases the efficiency of this process. Another way to increase the efficiency of this process is by sonication which refers to the passing of high-frequency sound energy towards the liquid.
Regulation of Temperature:
Some gasses dissolve at high temperatures whereas some dissolve at lower temperatures. By increasing or decreasing the temperature of liquid the gasses can be removed. This process is usually easy to perform and requires no special equipment. Similarly, continuous stirring and ultrasonication can increase the efficiency of this process. It means passing an ultrasonic sound to produce sound energy towards the liquid.
Use of membrane:
In this process, the polluted liquid is passed through a membrane. The membrane only allows the gasses to flow through it and restricts the liquid from flowing out. It is a relatively simple process with the added advantage of producing very pure solvents, as it prevents the redis solution of gasses into the liquid.
Using inert gases:
Adding inert gases to the solution may remove dissolved gases such as oxygen and carbon dioxide. This process is called sparging. To maximize the efficiency of this process the solution is vigorously stirred and bubbled for a long time. As inert gases such as helium do not mix easily with the liquids. Inert gases mainly used in this process are nitrogen, argon, and helium.
In this method, the impure solution is placed in a flask and frozen using liquid nitrogen, after which the flask is sealed to create a vacuum. Next, the frozen solution is relaxed by a warm water bath during which the gases escape as bubbles. This process is only applicable to separate a certain number of gases.
These are all the processes to detoxify the liquid to remove gases from it. The DÉGAZAGE CUVE À FIOULE ÎLE DE FRANCE uses one of the above methods to separate gases from the liquid present in the oil tank. By doing this process the safety of liquid removed from the oil tank is ensured. Thus, making it safe to release it into the sewage for further treatment of the liquid.
