***General Introduction***

This dataset contains data collected during experiments on optimising alkaline solvent regeneration through bipolar membrane electrodialysis for carbon capture. It is being made public both to act as supplementary data for publication and in order for other researchers to use this data in their own work.
This work was performed at Wetsus, European Centre of Excellence for Sustainable Water Technology, between July 2022 and January 2023. 
File: 2023_dataset_parametric_study_BPED_CO2_regneration.csv - includes the acquired data during the equibrium phases of the experiments in the parametric study.

All calculations are included in the manuscript. DOI: to be added

Current density (A*m-2): the applied current density
Theoretical L_K+ (n/a): the applied potassium load ratio, which is a dimensionless parameter representing the fraction of K+ ions that are expected to be transported across the CEM at a given current
Theoretical active [K+] (mol/L): the concentration of “active” potassium that can interact with CO2,
Influent Q (mL/min): influent flowrate to the BPED system,
Avg CO2 flowrrate (ml/min): measured average flow rate of CO2 exiting the regeneration system,
STDEV CO2 flowrrate (ml/min): calculated standard deviation in flow rate of CO2 exiting the regeneration system
pH acidic (n/a): pH measured inline of the acidic compartment
pH alk (n/a): pH measured inline of the alkaline compartment

[K+] effluent (mol/L): the potassium concentration measured in the effluent
[K+] acid (mol/L): the potassium concentration measured in the influent
[SO42-] influent (mol/L): the sulphate concentration measured in the influent 
[SO42-] effluent (mol/L): the sulphate concentration measured in the effluent

TIC influent (mol/L): the TIC concentration measured in the influent 
TIC effluent (mol/L): the TIC concentration measured in the effluent
TIC acid (mol/L): the TIC concentration measured at the sample point after acidic compartment and before the alkaline compartment
