Embodiment Construction

[0021] figure 1 An experimental crude oil deacidification device is shown, which mainly includes: deacidification agent tank 1, deacidification agent transfer pump 2, crude oil tank 3, crude oil transfer pump 4, packed tower 5, crude oil tank after deacidification 6. Sedimentation and separation device 7, electrode plate 8 and alkali slag tank 9.

[0022] As the name implies, the deacidification agent tank 1 and the crude oil tank 3 are respectively used to accommodate the deacidification agent and crude oil to be treated, while the deacidified crude oil tank 6 and the alkali residue tank 9 are respectively used to accommodate the deacidified crude oil and alkali scum. The deacidification agent transfer pump 2 is connected to the deacidification agent tank 1 to transfer the deacidification agent, and the crude oil transfer pump 4 is connected to the crude oil tank 3 to transfer crude oil to be treated.

[0023] The packed tower 5 is connected to the deacidifying agent transf...

Abstract

The present invention provides a crude oil deacidification apparatus, which comprises: a deacidification agent tank for accommodating a deacidification agent and a crude oil tank for accommodating crude oil requiring a treatment; an after-deacidification crude oil tank for accommodating the deacidified crude oil and an alkali residue tank for accommodating alkali residue; a deacidification agent transmission pump connected with the deacidification agent tank and a crude oil transmission pump connected with the crude oil tank; a filler tower, wherein a filler is arranged inside the filler tower, and a deacidification agent and crude oil are respectively conveyed to the filler tower through the deacidification agent transmission pump and the crude oil transmission pump, and are subjected to a reaction in the filler tower; and a sedimentation separation device, wherein the sedimentation separation device is connected with the filler tower and receives a deacidification agent and crude oil mixed liquid from the filler tower after the reaction. The present invention further provides a crude oil deacidification method. According to the present invention, the filler tower is adopted as a chemical reactor in the crude oil deacidification apparatus, such that the crude oil and the deacidification agent can be subjected to a complete reaction so as to achieve a good deacidification effect; and with the filler tower, emulsification phenomenon can be significantly improved.

Description

technical field [0001] The present invention relates generally to chemical reaction devices and methods, and more particularly to crude oil deacidification devices and methods. Background technique [0002] With the sustained, steady and rapid growth of the national economy, my country's oil demand is also increasing year by year. On the other hand, with the deep exploitation of oil resources, the output of high acid value crude oil is increasing year by year. High acid value crude oil not only has a high acid value, but also contains various impurities, so it is difficult to refine and process, but its price advantage is very obvious, so it is still widely used. The study found that when the acid value of crude oil is higher than 0.3mg(KOH) / g, it will have a certain impact on the refining process. If the acid value of crude oil is higher than 0.5mg(KOH) / g, it will cause obvious corrosion to crude oil transportation and refining equipment. [0003] Crude oil mainly contai...
