Abstract
A substance dispensing system including a first pressure vessel defining a first interior space; a first substance positioned in the first interior space; a first portion of a first propellant positioned in the first interior space; and a first portion of a second propellant positioned in the first interior space. At least 90 percent by weight of the first propellant is at least one of carbon dioxide, nitrous oxide, and combinations thereof. At least 90 percent by weight of the second propellant is at least one of nitrogen, argon, helium, oxygen, and combinations thereof.
Claims20
A substance dispensing system comprising:
- a first pressure vessel defining a first interior space;
- a first substance positioned in the first interior space, the first substance being in a liquid phase;
- a first portion of a first propellant positioned in the first interior space;
- and
- a first portion of a second propellant positioned in the first interior space;
- wherein the first propellant is at least one from the group consisting essentially of carbon dioxide, nitrous oxide, and combinations thereof,
- wherein the second propellant is at least one from the group consisting essentially of nitrogen, argon, oxygen, helium, and combinations thereof, and
- wherein a weight ratio of the second propellant to the first propellant in the first interior space is from 1:100 to 50:100.
A substance dispensing system comprising:
- a first pressure vessel defining a first interior space;
- a first substance positioned in the first interior space, the first substance being in a liquid phase;
- a first portion of a first propellant positioned in the first interior space;
- a first portion of a second propellant positioned in the first interior space, and substantially in a gas phase of the first interior space;
- a second pressure vessel defining a second interior space;
- a second substance positioned in the second interior space, the second substance being in a liquid phase;
- a second portion of the first propellant positioned in the second interior space;
- and
- a second portion of the second propellant in the second interior space and substantially in a gas phase of the second interior space;
- wherein a weight ratio of the second propellant to the first propellant in the first interior space is from greater than zero to 50:100,
- wherein a weight ratio of the second propellant to the first propellant in the second interior space is from greater than zero to 40:100, and
- wherein the first propellant and the second propellant are free of hydrocarbons, hydrofluorocarbons, and chlorofluorocarbons.
