Fluid Treatment of High Emulsification Degree

———

Aiming to promote the technological breakthrough and efficient development of shale oil in China, basingon the dehydration problems of Shengli shale oil, including small particle size of droplet, high interface filmpressure and high emulsification degree, an integrated device for shale oil dehydration with full gravitybalance has been independently developed.lt can realize the high efficiency and rapid dehydration of shale oilin a cost effective way.
Return to Product Introduction

Shale oil difficult dehydration treatment technical service project ( dehydration treatment scale 3000m³/d)

 

The integrated device integrates oil-gas-water separation, high-frequency pulse intelligentdehydration, natural gas multi-stage separation, demisting and buffering as a whole, belonging to a kind of apressure-closed and short process dehydration technology for shale oil.

 

The integrated device has been successfully applied to shale oil treatment in Shengli National Shale OilDemonstration Station, with total treatment capacity as 3,000m³/d, The incoming liauid water cut is 5% 68%, and the index is 0.1 8% at outlet on average, meeting the oil export index (water content < 1.5%). Foroutlet water, the oil content is 7.85 mg/L on average.

 

Compared with traditional process, the treatment temperature is 75 '℃, reduced by 5 '℃ ~ 10 ℃, thedemulsifier concentration is 300 mg/L,reduced by 60% ~ 70%, and the energy consumption of oiltreatment per ton (4.04 kgce) is reduced by 20%~30%, The land occupation is reduced by 62%, and theoperating cost per ton of oil is reduced by 35% to 40%.
