N2 - Post-combustion carbon capture is a well-established technology for removing CO
from industrial emissions. However, research is still underway to
optimise the process and make it more energy efficient. The current work
aims to present the results from pilot-scale (with a capacity of 1 tonne CO/day) studies of CO
capture conducted at Amager Bakke, a Waste-to-Energy facility in
Copenhagen, Denmark. The pilot operation is fully automated, and the
process control structure helps achieve multiple steady states
at regular intervals. In addition, the pilot is capable of several
configurations which can assist in optimising the energy required for
solvent regeneration. The current work discusses the base case configuration of the pilot plant by employing 30 wt MEA as the solvent. Experiments were conducted to analyse the influence of reboiler duty, solvent flow rate, and gas flow rate
on the pilot’s performance. The influence of these parameters on
several aspects is discussed in detail, and recommendations for the
optimal operation of such plants are provided. An optimum specific
reboiler duty of 3.46 GJ/tonne CO is obtained at a solvent flow rate of 306 kg/h, flue gas flow rate of 113 kg/h, and reboiler duty of 17.5 kW excluding heat loss.
