Dehydration of Crude Oil for ASTM D2892, Distillation of Crude Oil according to annex X1
D2892 requires that crude oil contain less than 0.3% water. But many crude oils contain more than 0.3% water and cannot be tested until they are dehydrated.
The B/R crude oil dehydration system performs a quick, atmospheric distillation. The light portion of the crude oil and the water are distilled into a chilled receiver shaped like a funnel.
Two phases are formed with water on the bottom and the light crude oil fraction on the top. Chilling of the receiver prevents any loss of the volatile components. Butane is collected separately in special butane traps.
When the process is complete, it automatically stops. Water can be drawn off the bottom through a valve. The light crude oil fraction is returned to the boiling flask (after cooling)
Now the crude oil is dehydrated and D2892 can be successfully performed.
Why can't I perform D2892 on a "wet" crude oil?
Distilling "wet" crude oil is difficult and yields poor quality results.
ASTM D2892 requires crude oil to have less than 0.3% water content.
The B/R dehydration system successfully separates all types of water contained in crude oil regardless of the form. It fully complies with ASTM D2892 requirements.
