1. Crude oil exploitation: In the process of crude oil exploitation, crude oil, gas andwater in the underground oil layer are mixed and produced. Due to the change of formation pressure and stirring in the process of mining,it is easy to produce foam. These foamwill expand the volume of produced liquid in the oil well and affect the normal production efficiency of crude oil. The use of crude oil defoamer can quickly eliminate these foamand improve oil recovery efficiency.
2. Petroleum refining: In the process of petroleum refining, defoamer can effectively control and eliminate the foam in the crude oil refining process (especially in the production of oil-water separation, oil-gas separation section and continuous reforming unit) . Defoamers have the characteristics of high temperature resistance, acid and alkali resistance, saltresistance and mineralization resistance, and can maintain efficient defoaming and foam suppression performance under various harsh conditions.
3. Oil transportation and storage: In the process of oil transportation and storage, defoamer can effectively prevent the generation of foam to ensure the safety and stability of oi1. This helps to reduce the occurrence of safety accidents such as oil spills and reduce therisk of pollution to the environment.
