Bench scale Quickfit™ equipment allows for reaction of samples (rock, soils, metal fittings, etc.) with fluids and carbon dioxide, to investigate the role of CO₂ in leaching metals and metallic elements from samples.

The equipment has previously been used to determine extent of steel corrosion, but primarily for the determination of trace metal concentrations, which can be leached from CCS reservoir sandstones with CO₂. In the UK context this may pose an environmental risk, if metal leaching is significantly higher than current oil and gas activities.

Fluid:sample ratios, temperatures, and CO₂ flow rate can be adjusted, for experiments at atmospheric pressure. Fluid samples can be taken for analysis e.g. pH, dissolved inorganic carbon, cation and anion concentrations. The laboratory is self-contained with respect to sampling and storage of samples. pH measurement (in-situ, or of samples) can be undertaken within the laboratory.

  • 250mL Quickfit™ borosilicate flasks and condensers with heating elements (x4)
  • Gaseous CO₂ flow to flasks at 1atm
  • Working temperature range 20-100°C
