From the refinery to the user, the oil has to go through multiple links, and the evaporation loss during loading and unloading is quite large. According to the actual value of oil and gas recovery in the United States, it is estimated that each loading and unloading has a volatile loss of 0.18%, and the loss rate is 0.72% for four loading and unloading. Therefore, ZS-221 solar heat reflection and anti-corrosion coating technology can also be used for storage tanks, pipelines, tank trucks, etc., to protect against sun exposure and reduce oil temperature, which is beneficial to reduce evaporation loss during loading and unloading.
Water cooling is a common method used in the summer of vaulted gasoline tanks. Spray with a lower temperature water, t table can be lower than the t ring. Using ZS-221 solar heat reflection and anti-corrosion coating technology of Beijing Zhisheng Weihua Chemical Co., Ltd., the tank top t table is higher than the t-ring, and its surface cooling effect is not as good as that of watering, but it has the following advantages:
(1) It takes a long time to reduce evaporation loss. “Little Breathing†and “Big Breathing†are available all year round. According to Shanghai Petroleum Corporation, the average "small breath" loss of the 5000m3 vaulted gasoline tank is 197kg when the oil temperature is only 10 °C. It can be seen that the loss in the spring and autumn season is also quite a lot. With the water spray method, it will not stop all year round; and Zhisheng ZS-221 solar heat reflective anti-corrosion coating technology is working all the year round.
(2) It is more convenient to use. Although the water spray cooling operation is simple, it cannot be uninterrupted water spray, so it is necessary to correctly grasp the start and end time of the spray water. Spraying with water tends to exacerbate the corrosion of the tank and cause the tank to become rusty. Relatively speaking, ZS-221 solar heat reflective anti-corrosion coating technology has anti-corrosion function, which is also conducive to the beauty of the tank area.
(3) Saving valuable water resources and power resources, as well as environmental protection and safety benefits. From the ZS-221 solar heat reflection and anti-corrosion coating technology, it has excellent weather resistance, water resistance, yellowing resistance, non-powdering, heat and humidity resistance, salt spray resistance and mildew resistance. It is more than 8 years old. The service life also reduces maintenance costs.
(4) ZS-221 solar heat reflection and anti-corrosion coating technology (thickness 0.25mm). A 5000m3 tank can save about 15t of gasoline per month. For vaulted gasoline tanks and internal floating roof tanks with frequent operations, the cost can be recovered in less than half a year.
Technology and technology are the key. The preliminary application and analysis of ZS-221 solar heat-reflecting anti-corrosion coating technology using new technology shows that the “sunlight over-temperature†on the surface of the tank and the temperature of the oil and gas in the tank can be significantly reduced, and the heat insulation effect is obviously good. In silver paint. In the summer, the floating roof tank can be lowered by more than 20 °C, and the vaulted tank can be lowered by 10 to 20 °C, which can replace the water spray to cool down. It is estimated that the "small breath" loss of the vault canister can be reduced by more than 80%, and the "big breath" loss can be significantly reduced.
In the past decade or more, China's coating manufacturing technology has been greatly improved. According to our understanding of the anti-solar radiant heat raw materials and the best insulation effect construction methods and coatings development experience, as well as a large number of facts and experimental data listed above, using ZS-221 solar heat reflection insulation anti-corrosion coating technology It is indeed feasible to achieve high-efficiency energy-saving storage tanks that make the storage tanks "not hot" and reduce the storage loss of oil and gas reservoirs, and the application fields are very wide: various industrial and civil equipments and facilities that are afraid of heat. Such as: petroleum (chemical) system of various open-air oil (gas) pipelines, pressure vessels, gasoline tanks, kerosene tanks, light diesel oil tanks, liquefied petroleum gas tanks, movable board houses, galvanized iron workshops (top), high-end buildings Walls, containers, limousines and special transport compartments (tanks) and the surface of the ship.
“Sunburn†is a special function of ZS-221 solar heat reflective anti-corrosion coating technology: it can reduce energy consumption, reduce evaporation loss of light liquid products, prevent overheating and boosting of compressed gas storage tanks, and reduce fire and explosion accidents. Hidden dangers, preventing the shipments from spoiling too quickly; and ZS-221 solar heat reflective anti-corrosion coating technology has excellent weather resistance and water resistance, yellowing resistance, no powdering, heat and humidity resistance, salt spray resistance, mildew resistance Performance; its service life of more than 8 years also reduces maintenance costs. For indoor objects that are afraid of being heated by the infrared radiation of other heat-generating objects (such as liquefied petroleum gas cylinders, etc.), they also have a good heat-proof effect. ZS-221 solar heat reflection and anti-corrosion coating technology will not only save electricity, water, environmental protection and safety, but will also obtain better economic benefits and huge social benefits.
