The oil industry is currently inclined to establish large oil storage units. As air, light, heat and metal effects lead to low oil quality, the establishment of oil storage tanks should therefore be characterized by the following:
1 - being a buffer in a way that does not absorb the oil because any absorption rate leads to bad results for the storage of oils later.
2. Building materials for tanks should be physically and chemically inactive for oil.
3 - to be isolated from light and air, which accelerate the process of oxidation.
4. The temperature should be kept about 15 degrees to avoid changes caused by oil freezing at low temperature or accelerated oxidation at high temperature.
Underground tanks seem to be ideal and storage is ideal if accompanied by a good interior coating. Particular importance should also be given to the materials used to paint tanks from the inside. Since glass is considered the most important inert material, this material has been successfully used to cover the internal parts of the tanks, but the exposure to fracture makes it expensive. As for ceramics, it seems to cause some problems as a result of the partial absorption of oil.
Particular importance should be given to the joints so that they are not affected by the acidity of the oil, the effluents caused by the impurities and the water deposited in the bottom of the reservoirs.
Recently, the use of special epoxy resins has yielded good results if this material is inert for oil, easy to paint and durable for a long time, due to the ease of working in reservoirs located above the surface of the earth and the low cost compared to the built under the ground has been established reservoirs Of stainless steel and fiberglass tanks (PVC). The results obtained were very good.
The periodic lubrication of good oils during storage is necessary and very important in order to remove the water and various impurities from the bottom of the reservoirs, which usually contain a large amount of fermented sugars and corrosive protein materials, which usually lead to the corruption of oil and conveying unpleasant odors. However, the buildup leads to increased oil ventilation and thus leads to increased oxidation. In order to get rid of the spoiling process, the base of oil tanks is built in an upside down pyramid. This method allows deposition of impurities and water to the bottom of the pyramid where it is easy to get rid of them by means of a special faucet installed to this end at the bottom of the tank.
