wOur successful Application oil come-up from water promptly wash oil tech, by the washing layer, improved water-oil separating speed, ascent rate is accelerated greatly.
(3) add thermal Release Technology
Separation temperature is high more, and separating effect is good more, but the energy consumption increase, therefore under the situation of guaranteeing the crude oil good separating effect, separation temperature is low more good more.Establish heater from device more than the oil-water interfaces in efficient small-sized oil and gas and water, reduced sewage intensification hear rate as far as possible, it is about 5% to save hear rate, and oil heats up 4～5 ℃, strengthens the oil-water ratio method of double differences, is convenient to dehydration, has reduced equipment manufacturing cost simultaneously.
(4) stainless steel dual damascene calendering filler is assembled dehydration technique
Select stainless steel dual damascene calendering filler, for providing more impact surfaces, amasss drop, the double wave card constantly changes because of the sheet separation, the cross section, fluid passage constantly changes, quicken breaking of emulsion droplet, promoted the coalescent of profit particle, increased particle diameter, improve sedimentation and ascent rate, accelerated water-oil separating speed.Preferred stainless steel dual damascene calendering packing layer thickness has satisfied droplet congregating and separation requirement.
(5) effect of air supporting dehydration
Under controlled pressure, a large amount of solution gas is arranged in the oil, and bubble is little, be evenly distributed, reduced oil phase density, strengthened the oil-water ratio method of double differences, oil emulsion easily adheres on the bubble, utilizes the buoyancy of gas, has increased ascent rate, as particle diameter is the oil droplet of 1.5 μ m, ascent rate is not more than 0.001mm/s, stick on the bubble after, ascent rate increases about 900 times, along with water-oil separating and oil reservoir rise, pressure diminishes, and gas expands, and it is big that bubble diameter becomes, even bubble breaks, be convenient to assemble and Gravity Separation, quickened oil, moisture can obtain better dehydrating effect from speed.
(6) other
A, efficient minitype vertical type oil and gas and water are separated through liquid distributor free water major part from device, having reduced sewage enters the heating separating layer and enters stainless steel dual damascene calendering packing layer, surfaceloadingrate diminishes and uses heat to reduce, and helps improving dewatering efficiency, the apparatus arrangement compactness;
B, at the less characteristics of associated gas, simplified gas fractionation unit energetically;
Pneumatic control instrument, automatic control level advanced person have been adopted in C, oil, gas, the control of water three tunnel flow processs.
