https://doi.org/10.1016/j.ijggc.2015.12.009 ” The flow rate of steam to the reboiler is increased rapidly to 200% at t = 0 and remains at this value for 41 min, while all
https://doi.org/10.1016/j.ijggc.2015.12.009 ” Although similar to the previous scenario, a significant difference is that flue gas is continuously fed to the absorber column during reboiler steam
https://doi.org/10.1016/j.ijggc.2015.12.009 ” Before the capture plant decoupling scenario is initiated, the plant is operating at steady state baseload. The flow rates of steam and gas
https://doi.org/10.1016/j.ijggc.2015.12.009 ” Due to the nature of the shutdown sequence, which involves a continued circulation of solvent at 30% of baseload in order to lower
https://doi.org/10.1016/j.ijggc.2015.12.009 ” The shutdown sequence is initiated at t = 0 min as shown in Fig. 6a. Steam flow rate is ramped down to zero over 10 min at a rate
https://doi.org/10.1016/j.ijggc.2015.12.009 ” A novel liquid sensor which differs from previous online measurement techniques (e.g. van Eckeveld et al., 2014) has been developed in-house at Edinburgh University.
https://doi.org/10.1016/j.ijggc.2015.12.009 ” Calculated real-time solvent capacity measurements are plotted against the temperature at the hottest part of the absorber during baseload operation, at 4.65 m of
https://doi.org/10.1016/j.ijggc.2015.12.009 “Based on the analysis of 14 triplicate measurement sets, 42 measurements in total, the expanded repeatability (k = 2) is estimated to be ±4.54% of the
https://doi.org/10.1016/j.ijggc.2015.12.009 ” To effectively understand the impact of dynamic scenarios on solvent CO2 loading at the absorber inlet and outlet, time-shifting is utilised in order to
