Abstract
Provided herein are methods, apparatus, and systems for delivering carbon dioxide as a mixture of solid and gaseous carbon dioxide to a destination.
Claims63
A method for intermittently delivering a dose carbon dioxide in solid and gaseous form to a destination comprising
- (i) transporting liquid carbon dioxide from a source of liquid carbon dioxide to an orifice via a first conduit, wherein
- (a) the first conduit comprises material that can withstand the temperature and pressure of the liquid carbon dioxide, and
- (B) the pressure drop through the orifice and the configuration of the orifice are such that solid and gaseous carbon dioxide are produced as the carbon dioxide exits the orifice;
- (ii) transporting the solid and gaseous carbon dioxide through a second conduit,
- wherein the ratio of the length of the second conduit to the length of the first conduit is at least 1:1;
- and
- (iii) directing the carbon dioxide that exits the second conduit to a destination.
An apparatus for delivering solid and gaseous carbon dioxide comprising
- (i) a source of liquid carbon dioxide;
- (ii) a first conduit, wherein the first conduit comprises a proximal end operably connected to the source of liquid carbon dioxide, and a distal end operably connected to an orifice, wherein the first conduit is configured to transport liquid carbon dioxide under pressure to the orifice, and wherein the orifice is open to atmospheric pressure, or close to atmospheric pressure, and is configured to convert the liquid carbon dioxide to a mixture of solid and gaseous carbon dioxide as it passes through the orifice;
- (iii) a second conduit operably connected to the orifice for directing the mixture of gaseous and solid carbon dioxide to a desired destination, wherein the second conduit has a smooth bore, and wherein the ratio of the length of the first conduit to the length of the second conduit is less than 1:1.
A system for delivering solid and gaseous carbon dioxide in an intermittent manner at doses of carbon dioxide of less than 60 pounds, with a time between doses of at least 5 minutes, wherein the system is configured to deliver repeated doses with a ratio of solid to gaseous carbon dioxide of at average of least 1:1.5 in each dose, in less than 60 seconds per dose, at an ambient temperature of 35° C. or less.
An apparatus for delivering solid and gaseous carbon dioxide in low doses in an intermittent manner of repeated doses of solid and gaseous carbon dioxide comprising
- (i) a source of liquid carbon dioxide;
- (ii) a first conduit, wherein the first conduit comprises a proximal end operably connected to the source of liquid carbon dioxide, and a distal end operably connected to an orifice, wherein the first conduit is configured to transport liquid carbon dioxide under pressure to the orifice, and wherein the orifice is open to atmospheric pressure and is configured to convert the liquid carbon dioxide to a mixture of solid and gaseous carbon dioxide as it passes through the orifice;
- (iii) a valve in the conduit between the source of carbon dioxide and the orifice, to regulate the flow of liquid carbon dioxide;
- (iv) a heat source operable connected to the section of conduit between the valve and the orifice, and to the orifice, wherein the heat source is configured to warm the conduit and orifice between doses to convert liquid or solid carbon dioxide to gas which is vented through the orifice.
