Embodiment 1

[0028] In a certain 3 million tons / year atmospheric and vacuum device in China, the modularized combined high-efficiency separation equipment with light-phase dispersed phase of the present invention is used to treat the electric desalination sewage therein.

[0029] Its specific operation process and effects are described as follows:

[0030] 1. Operating conditions of electric desalination wastewater

[0031] The main components are: under the volume flow rate, the oil content in water is 0.2-18%; the operating temperature is 40-65°C, and the operating pressure is 0.4MPa. like figure 1 As shown, since the oil is a dispersed phase and belongs to the process of deoiling in water, the oil bag is set on the top of the shell to recover the dirty oil, and because the content of the dirty oil in the water fluctuates widely, a two-stage combination is used for separation, that is, fluid distribution & Combination of rectification section, primary coarse granulation, primary enhanc...

Abstract

The invention belongs to the field of petrochemical engineering oil-water separation, and discloses a device for high-efficiently separating two-phase non-homogeneous mixed liquid such as petrochemical oil, water / acid / alkali and the like in a modularization manner. The modularization combination high-efficient separation device comprises a shell and an inner member, wherein the inner member consists of a fluid distribution and rectifying section, a coarsening part, an intensifying settling separation part and a nano fiber coalescence separation part. The shell is provided with a mixed liquid inlet part, a light-phase outlet part and a heavy-phase outlet part. The inner member is combined according to the ratio of the dispersion phase in the mixed liquid and the separation efficiency requirement, and the shallow-pool principle, the coarsening technology and the nano modified fiber high-efficiency coalescence technology are combined in a modularization concept, so that the non-homogeneous mixed liquid separation efficiency is high, and the adaptability in the application range is high.

Description

technical field [0001] The patent of the present invention relates to the field of petrochemical technology, in particular to a high-efficiency modularized combined high-efficiency separation method and equipment applied to petrochemical equipment. Background technique [0002] For a long time, the quality of my country's oil products has lagged behind, and the content of sulfur, aromatics and olefins in them is high, which has aggravated the pollution level of motor vehicle exhaust emissions and has become one of the driving forces for the frequent appearance of smog. With the increasingly stringent environmental protection regulations and the continuous upgrading of gasoline quality indicators, the demand for clean fuels in domestic and foreign markets continues to increase. [0003] At present, heavy oil processing technologies include delayed coking, residual oil hydrogenation and other technologies, and oil quality upgrades generally rely on hydrogenation technology.
