A method for removing particles from a high pressure flow stream entails flowing
the high pressure flow stream into an inlet of a high pressure trap and flowing
the flow stream from the inlet into a tube in the high pressure trap. The tube
is adapted to accelerate the flow stream. The flow stream leaves the tube and de-accelerates
as the stream flows into a chamber. The method continues by contacting the flow
stream with a plate wound helically around an outside surface of the tube. The
plate creates a cyclonic effect with the flow stream to remove particles from the
flow stream. The particles are collected in a reservoir. The remaining particles
are removed by flowing the flow stream towards a side outlet over the plate. The
methods end by collecting the remaining particles in a reservoir forming collected
particles and dumping the collected particles from the reservoir.
