Abstract

An improved vaporization system includes an automated valve and positive displacement pumping system using a pair of pumps operating in opposition to one another to provide continuous and constant volumetric flow at a constant predetermined pressure to an improved vaporizer using a stack of heated disks to flash vaporize the liquid. The valves are improved by providing one way flow.
