Abstract
The invention discloses a crude oil pretreatment method. The crude oil pretreatment method comprises the following steps of injecting 6% of fresh water in crude oil; sufficiently mixing the fresh water and the crude oil so that salt particles suspended in the crude oil can be dissolved in the fresh water sufficiently; adding moderate demulsifying agents in the mixture; gradually gathering tiny water drops in the crude oil into large water drops under the effect of a high-voltage electric field; and separating the large water drops from the oil in a settlement manner with the aid of gravity so as to achieve the purpose of desalting and dewatering. The crude oil pretreatment method is easy to operate and high in separation effect.
Description
Technical field
The invention belongs to the process field of crude oil, particularly, relate to a kind of pretreatment process removing salt and water in crude oil.
Background technology
Usually containing salt and water in the crude oil of directly gathering from oil field, if be not first removed through process, then not only can the production equipment of heavy corrosion petroleum product, also can cause waste fuel and cause the problems such as equipment scaling.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of pretreatment process of crude oil.
The present invention's adopted technical scheme that solves the problem is:
A pretreatment process for crude oil, comprises the following steps:
In crude oil, inject the fresh water of 6% and fully mix, the salt grain be suspended in crude oil is dissolved in fresh water fully, then appropriate emulsion splitter is added, under the effect of high-voltage electric field, the small water droplet in crude oil is made progressively to be gathered into larger water droplet, and power of relying on for support is settlement separate from oil, thus reach the object of desalting and dewatering.
To sum up, the invention has the beneficial effects as follows: crude oil upgrading method of the present invention is simple to operate, and good separating effect.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
Embodiment 1
A pretreatment process for crude oil, comprises the following steps:
In crude oil, inject the fresh water of 6% and fully mix, the salt grain be suspended in crude oil is dissolved in fresh water fully, then appropriate emulsion splitter is added, under the effect of high-voltage electric field, the small water droplet in crude oil is made progressively to be gathered into larger water droplet, and power of relying on for support is settlement separate from oil, thus reach the object of desalting and dewatering.
Crude oil upgrading method of the present invention is simple to operate, and good separating effect.
As mentioned above, the present invention can be realized preferably.
The above; it is only preferred embodiment of the present invention; not any pro forma restriction is done to the present invention; according to technical spirit of the present invention; within the spirit and principles in the present invention; the any simple amendment that above embodiment is done, equivalently replace and improve, within the protection domain all still belonging to technical solution of the present invention.
