The turnover and storage process often involves several operations such as reconciliation, tank dumping, loading and unloading, etc. In the process of oil transportation turnover and oil storage, the volume of gas phase space in the storage tank is affected by the changes of pressure, temperature and other factors. The physical characteristics of some oil components are higher than their boiling points, which leads to the evaporation loss of oil and gas. There are potential safety hazards in the whole storage process. When the concentration of oil vapor in a closed environment reaches a certain level, it is easy to cause fire and explosion, which not only pollutes the ecological environment, but also wastes energy. Evaporation of oil products not only causes the natural loss of a large number of existing oil resources, but also causes the density of oil products to change and the quality of oil products to decline. These problems have already attracted the attention of oil companies, and relevant laws, regulations, norms and standards have been formulated from the aspects of environmental protection, industry technology, safety management and resource recovery, and oil and gas recovery facilities of oil loading system have been set up. At the same time, in order to effectively control the evaporation of oil products and reduce the research results of air pollution, many different types of oil and gas recovery facilities have been applied in oil depots. It can ensure that the discharge of the treatment medium completely meets the treatment efficiency and tail gas emission concentration limit stipulated by the national laws and regulations, and complete the treatment of oil and gas pollution and the recycling of harmful substances. The reasonable selection scheme of oil and gas recovery facilities is economically applicable to the safe production and operation of the product oil depot, and the corresponding conclusions and suggestions are given.展开更多

Although accidents in oil depots have been greatly reduced in recent years, it is not without accidents. In case of accidents and fires, it is often the fire foam system that plays a key role. The fire sprinkler system is mainly used to cool down and prevent further expansion of the accident. The control of the foam fire extinguishing system has a great impact on the loss of the oil depot. Therefore, the acceptance of the fire sprinkler system in the early stage of the project became the key node of the completion acceptance milestone of the project construction. How to design and control the reasonable application of foam fire-fighting system in fire-fighting code. The safety measures of foam fire-fighting system in oil depot are mainly to determine the inlet pressure based on the number of foam generators, foam feed pump, foam supply volume, foam supply strength and pressure loss of pipelines, so as to enable the foam generators to function and operate to achieve the best fire-fighting effect.展开更多
