ABSTRACT:
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.
