| description | The invention discloses a desalination and deacidification processing method for crude oil. The method comprises the following steps: the crude oil is unloaded to a tank, a demulsifier is added, gradual heating is carried out, the temperature is kept at 45 to 65 DEG C, dehydration is regularly carried out on the crude oil, and sampling analysis is carried out; after settling separation is completed, lighter crude oil in the upper part of the tank is diverted to a lighter crude oil tank, the demulsifier is added continuously, heating is carried out until the temperature is at 45 to 65 DEG C, and sampling analysis is carried out on the oil body in the tank; dehydration separation continues to be carried out in the lighter crude oil tank, oil body located on the upper part of mudimpurities is poured to another tank, reversed pouring and demulsifier adding are carried out for many times when poured to the another tank until the sample achieves requirements; a chemical light oilproduct achieving the requirements is diverted to a chemical light oil product tank for continuous reforming separation or directly for continuous reforming separation, and a heavy oil product achieving the requirements is diverted to a heavy oil product tank for coking processing or directly for coking processing. The desalination and deacidification processing method for crude oil has the advantages that the operation is safe, the cost is lower, processing effects are better, and better environmentally friendly performance is achieved. |
