Abstract:     A separator for substantially resolving at least one component of a process stream, such as from the exhaust of an internal combustion engine. The separator includes a body defining a chamber therein. A nozzle housing is located proximate the chamber. An exhaust inlet is in communication with the nozzle housing and the chamber. A nozzle assembly is positioned in the nozzle housing and includes a nozzle moveable within and relative to the nozzle housing. The nozzle includes at least one passage formed therethrough such that a process stream entering the exhaust inlet connection passes through the passage formed in the nozzle, which imparts a substantially rotational flow to the process stream as it enters the chamber. A positioning member is configured to position the nozzle relative to the nozzle housing in response to changes in process stream pressure to adjust flowrate of said process stream entering into the chamber.

First Claim:
Show all 36 claims
We claim:     1. In a system producing at least one process stream of varying pressure, a separator for facilitating management of components of the at least one process stream, the separator comprising:
  • a body defining a chamber;
  • a nozzle housing;
  • an exhaust inlet connection in flow communication with said nozzle housing and said chamber; and
  • a nozzle assembly substantially disposed in said nozzle housing so that said process stream entering said exhaust inlet connection passes through at least a portion of said nozzle assembly and into said chamber, said nozzle assembly configured to adjust flowrate of said process stream into said chamber in response to changes in process stream pressure and to impart a substantially rotational motion to said process stream passing into said chamber so as facilitate substantial resolution of at least a first component of said process stream.
