GN solids control provides the engineering and design of 3-phase separator internals that target high gas volumes and primary L/L dispersions.

Our scope includes the design, engineering and delivery of

 

  1. a) The inlet gas distributor
  2. b) The foam breaker along with the the L/G separator
  3. c) The dimensional design of the inlet compartmeent, the settling compartment and

the product outlet compartment

  1. d) The separation of the aqueous and hydrocarbon liquid phases utilizing ether plate pack type or wire mesh coalescers Ensepatec provides a process guarantee for

 

1) The removal efficiency of liquid droplets in the gas stream and the maximum liquid content in the outlet gas stream

2) The maximum content of water in the oil phase

3) The maximum ppm-level of oil in the water outlet flow

 

Materials of constructions are high grade stainless steel or nickel-based alloys

 

 This design eliminates the need for a liquid interface controller. Both the oil and water flow over weirs where level control is accomplished by a simple displacer float. The oil overflows the oil weir into an oil bucket where its level is controlled by a level controller that  operates the oil dump valve. The water flows under the oil bucket and then over a water weir. The level downstream of this weir is controlled by a level controller that operates the water dump valve.

The height of the oil weir controls the liquid level in the vessel. The difference in height of the oil and water weirs controls the thickness of the oil pad due to specific gravity differences. It is critical to the operation of the vessel that the water weir height be sufficiently below the oil weir height so that the oil pad thickness provides sufficient oil retention time. If

the water weir is too low and the difference in specific gravity is not as great as anticipated, then the oil pad could grow in thickness to a point where oil will be swept under the oil box and out the water outlet. Normally, either the oil or the water weir is made adjustable so that changes in oil/water specific gravities or flow rates can be accommodated.
