You have been asked by a leading energy production company to investigate the feasibility of improving the efficiency of an existing coal-fired power plant by moving towards a new coal-biomass fuelled carbon capture site. The upgrade will involve four sections of the overall power plant chain:
1. Evaluating the combustion process – The company would like to understand the air requirements of the coal-biomass blend in order to maximise CO2 for potential carbon capture and storage.

2. CO2 absorption reactor design – The flue gases from the combustion process are to be transported further downstream to an absorption reactor which is required to remove 95.0% of the CO2 emissions from the gas stream using an alkanolamine solvent.

3. Capillary curves – Porous reservoirs are frequently saturated by multiphase mixtures, e.g. oil and water, or oil and natural gas, or oil and CO2. Due to gravity heavier phases are predominantly located at the bottom of the reservoir, and lighter phases lie on top. The boundaries between the phases are smeared by capillary effects. The capillary pressure data are particularly required for predictions of reservoir initial fluid saturations.

4. Reservoir evaluations using permeability curves – The presence of a second phase can, depending on its distribution in the porous network, hinder the flow of the first phase. Various attempts have been made at describing two-phase flow in porous media where the extension of Darcy’s law is a very commonly used approach. Within this approach, the principle functional relationship remain as in the single-phase Darcy’s law, but coefficients are generally made phase-specific and permeability is made saturation dependent.
