Beschreibung
Zusammenfassung:	The invention discloses a crude oil dehydration method. The crude oil dehydration method provided by the invention utilizes microwave radiation for heating crude oil to be processed. The microwave radiation heating temperature is 40-70 DEG C; and the temperature increase rate of the crude oil heated by microwave radiation is 1 DEG C/min at least. Experiments prove that, compared with the crude oil which is heated by water bath and the crude oil which is not processed, the settlement dehydration speed of the crude oil heated by microwave radiation is greatly improved, the final dehydration rate of the crude oil is increased, the water content in the crude oil after settlement dehydration is reduced, the wall-cling phenomenon of the crude oil after dehydration is weakened, and sewage after dehydration is relatively clear. The crude oil dehydration method brings a new revolution for economic, high-efficient, clean and fast purification and transportation of the crude oil and the ground processing technology of t
