Patent ID: 8574408

Claim:
A method of recirculating a fluid in a particle production system, the method comprising: producing a reactive particle-gas mixture from a precursor material and a working gas in a particle production reactor; receiving a conditioning fluid at a fluid inlet of a quench chamber and receiving the reactive particle-gas mixture from the particle production reactor at a reactive mixture inlet of the quench chamber; mixing the conditioning fluid with the reactive particle-gas mixture in the quench chamber, thereby producing a cooled particle-gas mixture, the cooled particle-gas mixture comprising a plurality of precursor material particles and an output fluid, the output fluid including the conditioning fluid; receiving and filtering the output fluid from the quench chamber using a filter element, thereby producing a filtered output; receiving and controlling the temperature of the filtered output using a temperature control module, thereby producing a temperature-controlled, filtered output; receiving and modulating a content ratio of the temperature-controlled, filtered output using a content ratio control module, thereby producing a content-controlled, temperature-controlled, filtered output, wherein the temperature-controlled, filtered output comprises a distinct primary fluid and a distinct secondary fluid, and the content ratio is the ratio of the primary fluid to the secondary fluid; and supplying the content-controlled, temperature-controlled, filtered output to the fluid inlet of the quench chamber using a channeling element, wherein the content-controlled, filtered output is provided to the quench chamber as the conditioning fluid to be used in quenching the reactive particle-gas mixture.
