Description
The apparatus generates and maintains the desired confining pressure and temperature during porous media studies. It is particularly useful for NMR, CT scan and linear X-RAY experimental set-ups with composite core holders, when air baths cannot be utilized. The device consists of a high pressure syringe pump, an heated recirculation pump, a pneumatic dual valve, a fluid reservoir and two pressure transducers for pore and confining pressure monitoring. The syringe pump generates and maintains a constant pressure while the recirculation pump assures continuous flow in the confining circuit at high temperature. Consequently, the core sample mounted in the core holder is maintained under the same conditions of temperature and pressure. It can also be used to maintain a constant differential pressure between the pore pressure and confining pressure. By means of an Ethernet connection and a dedicated software, the unit can easily be programmed to perform elaborated pressure and temperature maintenance schedules.
