System and method for determining the phase envelope of a gas condensate

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 inlet pressure sensor operably associated with the entrance passageway of the microfluidic device;
• an output sample bottle in fluid communication with the exit 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;
• an outlet pressure sensor operably associated with the exit passageway of the microfluidic device;
• a temperature control device for controlling the temperature of the gas condensate in the microchannel;
• a camera operably associated with the microfluidic device;
• and
• a computer operably associated with the first pump, the inlet pressure sensor, the second pump, and the outlet pressure sensor for operating the first pump and the second pump to provide a desired pressure drop across the microchannel of the microfluidic device.
