Refining equipment decoloring effect on oil in the oil refining process

2020-11-21 15:36:17


There are many different kinds of device of the valve and classification method is very much also. According to the valve body material can be divided into cast iron valve, cast steel valves, forged steel valves, etc. Common are classified according to the valve structure characteristics, can be divided into the gate valve, globe valve, check valve, plug valve, safety valve, pressure reducing valve, etc. According to the drive mode can be divided into manual valve shutoff valve parts, power drive valve (solenoid valve, hydraulic valve, pneumatic valve, electric valve, etc.) and automatic valve (on line in the medium of energy to drive the valve itself, such as check valve, safety valve, pressure reducing valve, etc.). According to the nominal pressure can be divided into valves, low pressure valves, medium pressure and high pressure valves.

Refining equipment daily testing, refining equipment of all kinds of pipeline external inspection at least once a year, a comprehensive inspection at least every 6 years I, Ⅱ, Ⅲ pipeline key check at least once a year, Ⅳ, Ⅴ pipeline key check at least once every two years. Pipeline is the main external inspection observation pipe outside surface crack, corrosion and deformation defects, such as connecting flange have unbiased mouth, loose fasteners is complete, the presence of corrosion, the phenomenon such as use to listen to the sound method to check whether there is any foreign body on the tube of impact, friction, etc.

The present part of the big, medium, small equipment, refining equipment manufacturer small oil refineries with waste plastics, waste tires, waste oil refining gasoline and diesel, in its process due to the unreasonable process and raw material problem, make the end product of chromaticity, smell not meet user requirements, and later oil refining process of decoloring and for long-term storage of the oxidation, and can not meet the national standard. The oils are decoloring to MSG system must be taken to remove the hydrogen sulfide odor, oxidated gum, colloidal make dark, dirty oil, crystal clear, product appearance, transparency, odor removal, increase the security, stability, and to use standard, improve the economic value.
