Dual Inlet Separators!

"Dual Inlet Separators"

Say WHAT?

"where they are used in a plant?"

What do they separate?

Inlet separators are used to separate oil,water and gas from a pipeline emmulsion. Two phase separation is oil/water and is normally accomplished using heat and some settling, which makes the vessels relatively large.

Dual inlet separators means there are two in parallel before the plant.

Hi!

Maybe you mean dual outlet Separators, seldom is there a two feed separator. The Alfa Laval KRPX model is a dual outlet separator.This is normally used for separating coffee sludge from coffee extracts and also removing coffee oil from the same extracts. Oil is separated out from the central point of the separator by centripetal force, while the sludge is discharged out of the bowl peripherals drained to the bottom.

This is what I'm talking about! This vessel has two inlets of 3 phase fluid (water, condensate and gas)... The amount of Gas to oil ratio is high as the fluid is coming from a gas reservoir.

The two vessels shown are the "duel inlet separators" The first separates gas from the inlet. The gas is removed via stream #5. The second separtor receives the liquid (oil and water) from the first separator via stream #4. In the second separator the oil and water are separated. The oil being taken off as stream #7 and the water taken off as the stream coming from the bottom of the second separator. (Sorry, i can't quite make out the vessel tag numbers or all of the stream numbers)

As you can see these separators are in series not parallel.

This is a common installation just after the well head at a gas or oil well. There may or may not be some processing in terms of heat or chemical injection to aid the separation upstream of the separator inlet.

Ok, the drawing makes a clear description of what you have in mind. The inlet stream is from a single pipe from the source, but is feed or injected to the tank (separator) in two branched pipes. The dual inlet pipe is designed to reduce the inlet pressure from the pipeline, or could also be to distribute the spray inlet to the separator tank on both section of the vessel. The separator is normally under controlled vacuum so that the boiling point of either the gas or condensate is different from the water, allowing this to be removed as a gas phase, while the water condenses and is removed at the bottom side of the separator. Normally, there is a flash cooling effect when hot liquid is injected to a vacuum.
