  • System and method for producing and delivering vapor
    Patent number: 7680399
    Abstract: Systems and methods for producing and delivering vapor are disclosed. A vaporizer tank containing a liquid may be heated such that liquid within the tank is heated and vapor generated. The flow of this vapor to a destination may then be regulated. Embodiments of the present invention may control the temperature of this liquid such that a saturated vapor condition is substantially maintained in the vaporizer tank. The vaporizer tank is coupled to a mass flow controller which regulates the delivery of the vapor to downstream components. By substantially maintaining the saturated vapor condition within the vaporizer tank the pressure of vapor at the mass flow controller can be substantially maintained and a stable and consistent flow rate of vapor achieved.
