Tricanter Three Phase Decanter Centrifuge Aging Oil Treatment For Liquid Purification

General introduction of aging oil treatment

Based on the results of the aged oil test, the following processes are recommended for the separate treatment of the aged oil that cannot be recovered:

(1) The aging oil after dosing is pumped to the heating furnace for heating and heating, and the temperature rises to between 60 and 70 °C. The heated and aged oil is settled in the oil-water separator, the settled crude oil enters the oil system, and the separated sewage enters the sewage collection tank. Due to the poor quality and small amount of the separated sewage, these sewage cannot be directly entered into the sewage treatment system and must be treated in the next step. After the separated sewage reaches a certain amount in the sewage collection tank, the sewage pump and the sewage collection tank are used to form a circulation loop, and chemicals are added to circulate the sewage in the tank. After the chemicals and sewage are completely mixed, they will settle for a period of time, and then the bottom sewage will be input into the sewage treatment system, and a small amount of waste oil in the upper part will be sent back to the sewage oil treatment system.

(2) Due to the ubiquity of aged oil, it requires a large investment to build an aged oil treatment system in each combined station. Therefore, it is recommended to build a mobile aged oil treatment device, which can meet the requirements of the above-mentioned fixed treatment system. At the same time, it has great flexibility and can be used in rotation among the joint stations, which not only reduces equipment investment but also solves practical problems.

Process of decanter centrifuge for aging oil treatment

The centrifugal separation process is that demulsifier and flocculant are added to the aged oil by the automatic dosing device, and then sent to the centrifuge. Cylinder, the separated solid impurities are discharged by screw conveyor, and the commonly used centrifugal device also includes hydrocyclone. The centrifugal separation efficiency is higher than that of thermal sedimentation, and the equipment occupies a small area. In foreign countries, this process is often used to incinerate or biologically harm the separated solid impurities5. Take Unpure Company in the United States for example, first heat the aged oil to 150℃, above 1.03MPa, add a flocculant, then flash under reduced pressure through a venturi tube, and then send the pretreated aged oil to a centrifuge for centrifugation. The process can open the cage formed by solid particles to achieve the purpose of separation of solids, water and oil.

Characteristic of treating aging oil by decanter centrifuge

The disadvantage of centrifugation is that the one-time investment is large. Since its separation efficiency increases with the increase of rotation speed, centrifugation is used alone to achieve the ideal treatment effect, which requires high equipment and high operating costs. However, the centrifugal method occupies a small area and is especially suitable for use in areas with strict space requirements such as offshore platforms.
