Dehydration device for oilfield gathering and transportation

Abstract

The invention discloses a dehydration device for oilfield gathering and transportation. The dehydration device comprises two sets of drying tank devices and one set of storage buffer system; the dehydration result is judged through a control system to determine whether drying is carried out or not; a first drying tank for drying petroleum is included; a spiral first electrode is arranged in the first drying tank; a first end of the first electrode communicates with a first power supply; and electricity is provided to the first electrode through the first power supply. The steam humidity in the petroleum is detected through twice drying, meanwhile, steam detection is carried out on the petroleum which is dried twice again, the petroleum which is not dried up to standard is dried once again through a preparation tank arranged in the middle and the petroleum which is dried up to the standard is transported to an oil storage tank.

Description

technical field [0001] The invention relates to the technical field of dehydration devices, in particular to a dehydration device for oil field gathering and transportation. Background technique [0002] The crude oil extracted from the well generally contains a certain amount of water, and if the crude oil contains too much water, it will cause waste in storage and transportation, increase equipment, and consume more energy; most of the water in crude oil contains salts, which accelerates equipment, pipelines and pipelines. Corrosion; in the external refining process of petroleum, when water and crude oil are heated together, the water will rapidly vaporize and expand, and the pressure will rise, which will affect the normal operation of the refinery and product quality, and even cause an explosion. Therefore, before exporting crude oil, dehydration is required so that the water content does not exceed 0.5%. [0003] In view of the above-mentioned technical defects, the cr...
