Mobile X-ray/MRI/PET cells to image 4D fluid flow in porous media

Project: Equipment only

Project Details


This is a modular and configurable system that enables injection of liquids through porous media (such as sand packs, glass bead packs, and cylindrical rock cores), is compatible with X-ray, MRI and PET imaging, and is suitable for reactive flow experiments e.g. mineral precipitation, dissolution, and biofilm growth.

The main components of this equipment are:
1) Two dual piston isocratic injection pumps (Watrex DeltaChrom P102). Flows from 0.01 to 10 mL/min, 10 MPa max pressure, PEEK flow path for chemical compatability, no limit of injection volume, with pulse dampener.
2) Dual channel syringe pump (Chemyx Fusion 4000) offering pulseless and programmable injection/extraction at extremely low flow rates, volume limited by syringe volume, pressure limited by syringe type.
3) PEEK HPLC columns of various lengths and diameters (30mm length, 4.6mm internal diameter, 100 x 4.6, 250 x 4.6, 50 x 7.5). 10 MPa max pressure. Can be packed with loose sand or glass beads and imaged with X-ray/MRI/PET, but more suitable for X-rays due to their small size.
4) In-house designed and built 1" (25.4 mm) rock core holder. Max pressure 4 MPa at 25 °C. Can be imaged with X-ray/MRI/PET.
5) Digital pressure transducers continuously recording inlet pressure, outlet pressure, and confining fluid pressure (for rock core holders) allowing measurement of permeability.
6) Range of fittings, tubing, backpressure regulators, and sample injection options.
7) Computer for recording data and controlling pumps.
8) Mobile system intended to be moved to different imaging facilities.
