The invention provides an
oil field two-stage
dehydration treatment system and method. The
system comprises a control cabinet and a two-stage
dehydration device, the two-stage
dehydration device comprises a temperature sensor, a liquid level meter, a
pressure sensor and an
electric control part, wherein the temperature sensor, the liquid level meter, the
pressure sensor and the
electric control part are all electrically connected with the control cabinet, and the control cabinet is used for giving an alarm according to temperature, pressure and liquid level signals and controlling starting andstopping of the
electric control part. The pressure
transmitter and the temperature
transmitter are arranged on the ball receiving
barrel, so that the safety of a
station yard and equipment are protected; a liquid level meter is added to the dosing device, and dosing time is mastered at any time; the first
heating furnace is provided with a full-automatic
combustor, so that remote automatic ignition and
flameout protection are achieved, and the production
operation safety of
station personnel is improved; an associated gas outlet pressure remote
transmission function is added to the
buffer tank, and pressure remote transmission, over-limit alarm pump stopping, remote switching of the two pumps and emergency shutdown functions are added to the output pump, so that the number of times of on-site manual operation is reduced; meanwhile, a double-proportion drain valve is additionally arranged at the outlet of the associated gas separator to realize automatic drainage.
