Abstract
Disclosed is a dense fluid spray cleaning apparatus comprising a gas supply (3) for providing a predetermined amount of a gas to an enhanced joule-thompson condensation reactor (2) and for providing gas to a propellant generator (4), a premix chamber (6) for receiving a solid particulate from the enhanced joule thompson condensation reactor and heated gas from the propellant generator, and a mixing chamber (8) for receiving the solid particulate and the heated gas and producing a spray stream containing the solid particulate.
Claims13
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.
A method for producing a spray cleaning stream containing a solid particulate formed from a dense fluid comprising:
- producing a heated, dense fluid propellant;
- producing the solid particulate from a dense fluid using an Enhanced Joule-Thompson Condensation Reactor;
- indirectly mixing the heated, dense fluid propellant and the solid particulate in a premix chamber having inner and outer coaxial tubes, the inner coaxial tube for transporting the solid particulate and the outer coaxial tube for transporting the dense fluid propellant;
- and
- directly mixing the heated dense fluid propellant and the solid particulate received from the premix chamber to produce the spray cleaning stream containing the solid particulate.
