Abstract:
1. A dense fluid spray cleaning apparatus for producing a stream containing a solid particulate comprising: a dense fluid propellant generator fluidly connected to a dense fluid supply for producing a heated, dense fluid propellant; an Enhanced Joule-Thompson Condensation Reactor fluidly connected to a dense fluid supply for producing a solid particulate from the dense fluid; a premixer for indirectly mixing the heated, dense fluid propellant received from the propellant generator and the solid particulate received from the enhanced Joule-Thompson Condensation Reactor, the premixer including inner and outer coaxial tubes, the inner coaxial tube in fluid connection with the Enhanced Joule-Thompson Condensation Reactor and the outer coaxial tube in fluid connection with the dense fluid propellant generator; and a mixer for directly mixing the heated dense fluid propellant and the solid particles received from a premix chamber to produce a stream containing the solid particulates.
