Gas adsorption Isotherm System Unconventional reservoir Instruments

The system determines the adsorption isotherm for a combination of adsorbate (e.g. methane, CO2) and adsorbent (coal, shale, etc.). In other words, the apparatus evaluates at equilibrium the maximum volume of gas adsorbed onto an adsorbent at a specific temperature and pressure. This is achieved by means of the isothermal volumetric method in which the pressures and volumes of a reference and test cell held at constant temperature are continuously monitored.

The apparatus is fully automated, allowing computer-controlled gas injection, pressure monitoring and data acquisition. Up to four testing chambers can be integrated into the system to allow simultaneous and independent testing.
