Problems solved by technology

[0002] During the transportation and storage of mineral oil, a large amount of harmful gases such as VOC will be produced. On the one hand, it will cause waste of resources, and on the other hand, it will also cause pollution to the environment; in addition, during the inspection and cleaning of oil tank equipment, volatile Harmful gases such as VOC will bring great harm to the staff
Now in the industry, it is common to introduce nitrogen gas, which can discharge the air, avoid the explosion phenomenon caused by the contact between oil gas and oxygen in the air, and also have a sealing effect to reduce the volatilization of harmful gases such as VOC in the oil body, but this method needs more time. long time, very inefficient
[0003] At present, some liquid materials have been used as sealants for the safety protection of oil and gas equipment. They are placed on the surface of the oil body to form a liquid seal, reduce the volatilization speed of the liquid, and reduce the generation of harmful gases such as VOC, thereby reducing the impact on the staff. However, the current liquid seal materials used on the surface of the oil body spread slowly on the surface of the oil body, the active ingredients are easy to volatilize, the coverage of the oil body is low, easy to settle, and easy to be oxidized. These problems cause liquid The use efficiency of the sealing material is low, the cost is high, and it will cause secondary pollution, and there is a risk of combustion and explosion
