Abstract
A method and apparatus for accurately regulating the compressibility of a compressible fluid in a pumping system utilizing a single zone of controlled cooling. Cryogenic cooling is employed for cooling a pump head and a thermally integrated heat exchanger such that a single source of cryogenic fluid can be applied to the heat exchanger to increase the bulk modulus of the compressible fluid just prior to and during the pumping process.
