High Pressure Industrial Systems

The High Pressure Industrial Systems research group addresses challenges related to chemistry, scale-up and engineering materials in industrial processes at high pressure (typically up to 2000 atmospheres and usually at elevated temperature) by conducting detailed fundamental experiments and employing computational methods where appropriate to yield deeper insights.

The core research themes of the group are as follows:

Supercritical Fluids

show research

Focus is currently on the study of environments containing supercritical water (PC = 221 bar, TC = 374A?C) or carbon dioxide (PC = 74 bar, TC = 31A?C):

- Supercritical CO2 found in oil and gas wells and in transport and subsequent sequestration of CO2 deep underground, often together with toxic and/or corrosive contaminants e.g. hydrogen sulphide (H2S) and H2O.

- Supercritical H2O used as a working fluid in the power generation industry: nuclear and super- or ultra-critical power stations burning hydrocarbon-based fuels.

- Supercritical H2O as a reaction medium for oxidation, hydrolysis and/or dehydration e.g. the formation of the oxides and hydroxides of metals from their water-soluble salts.

Reaction Engineering & Catalysis

show research

- Development of a patented confined jet, supercritical water reactor (with Darr group, Dept. Chemistry, UCL) for the continuous manufacture of inorganic nanoparticles.

- Chemical synthesis in high pressure environments.

- Fundamental mechanistic studies of catalytic processes.

Design and Scale-Up Methodologies

show research

- Measurement of transport phenomena in high pressure reacting environments.

- Development of pilot plant and scale-up of confined jet reactor for the continuous production of inorganic nanoparticles (with Darr group, Dept. of Chemistry, UCL).

- Pressure equipment design and fabrication.

Materials Performance

show research

In-situ characterisation of engineering materials in high pressure, high temperature (HPHT) environments, approached from the fundamental perspective of materials science:

- Polymers & composites: thermoplastics, elastomers, thermosets.

- Ceramics, refractories and cements.

- Swelling and plasticisation, viscoelastic properties of polymers.

- Fluid sealing in HPHT environments.

- Chemical reaction and degradation.

- In-situ Raman and FTIR studies.
