Abstract
An automatic chemical feeding device for crude oil dehydration mainly consists of a settlement tank, a crude oil water content analyzer, a sewage oil content detector, a PLC (programmable logic controller), a frequency converter, a chemical feeding pump, a chemical flowmeter, a static mixer and a chemical tank. The settlement tank is located on an outdoor cement base. A chemical feeding pump chamber is arranged an inlet side of the settlement tank, the chemical feeding pump is mounted in the chemical feeding pump chamber, an inlet of the chemical feeding pump is in pipeline connection with the chemical tank, and the chemical flowmeter is mounted at an outlet of the chemical feeding pump and connected with a produced liquid pipeline from a well. Chemical liquid and produced liquid are mixed sufficiently through the static mixer and enter the settlement tank. Two pipelines are arranged at an outlet of the settlement tank, the crude oil water content analyzer is mounted on the finished oil pipeline, and the sewage oil content detector is mounted on the sewage discharge pipeline. The crude oil water content analyzer, the sewage oil content detector and the chemical flowmeter are respectively connected with the PLC electrically, the PLC is in output connection with the frequency converter, and the frequency converter is in output connection with the chemical feeding pump electrically. By the aid of the automatic chemical feeding device, the process of crude oil dehydration is automatic, quality of crude oil dehydration is improved, labor intensity of workers is reduced, work efficiency is improved, energy saving and emission reduction are benefited, and production management level of oil fields is improved greatly.
