Patent ID: 8380446

Claim:
A system for determining the phase envelope of a gas condensate, comprising: a microfluidic device defining an entrance passageway, an exit passageway, and a microchannel in fluid communication with the entrance passageway and the exit passageway; an input sample bottle in fluid communication with the entrance of the microfluidic device; a first pump operably associated with the input sample bottle for urging the gas condensate, disposed in the input sample bottle, into the entrance of the microfluidic device; an output sample bottle in fluid communication with the exit passageway of the microfluidic device; a second pump operably associated with the output sample bottle for pressurizing the gas condensate, disposed in the output sample bottle, in opposition to the first pump; and a temperature control device for controlling the temperature of the gas condensate in the microchannel, wherein the first pump and the second pump are operable to provide a desired pressure drop across the rnicrochannel of the microfluidic device.
