Abstract

Control system for a degasser comprising: a pipe formed separation chamber with an upstream end where fluid flow that is passed in by use of a spin element in the upstream end is set in rotation and separated to; a heavier fraction that essentially is accumulated along the inner pipe wall of the separation chamber and is taken out through an outlet in a downstream end of the separation chamber; and a lighter fraction essentially accumulated along the longitudinal axis of the separation chamber, from where an outlet pipe is arranged for delivery of the lighter fraction to; a control separator arranged to separate out any entrained heavier fraction from the lighter fraction, which entrained heavier fraction is taken out through an outlet pipe from a bottom zone filled with heavier fraction in the control separator, preferably for delivery thereof to the heavier fraction from the separation chamber, while the lighter fraction is taken out from the control separator through a separate outlet pipe; distinguished in that the control system is comprising a differential pressure transmitter for indication of differential pressure between the zones for the lighter fraction in the separation chamber and the control separator, in that said differential pressure is used as basis for regulating a valve in the outlet pipe for the lighter fraction from the control separator, and a level transmitter for indication of level of the heavier fraction in the control separator, in that said level is used as basis for regulating a valve in the outlet pipe for the heavier fraction from the control separator.
