Where 𝑉 ̇ is the lean solvent volumetric flow rate, LMTD is the log mean temperature difference, and k is the thermal conductivity. Surface compactness is assumed to be 150m 2 /m 3 as per Zohuri , while thermal conductivity values of 3894w/m 2 .K for the reboiler and 1932w/m 2 .K for the cross heat exchanger were taken from Woods . Log mean temperature difference (LMTD) was maintained at 6 o C for the reboiler and a minimum approach temperature of 5 o C was applied for the cross HX, leading to an LMTD of circa 7 -8.5 o C in all cases. Should high residence times in these pieces of equipment be found to increase degradation excessively, this can be mitigated by increasing the LMTD at the cost of increased irreversibility in the system, however this may results in adverse effects due to higher metal skin temperatures as only bulk liquid temperatures were considered in this analysis. Absorber and desorber sump levels were taken at 1.1 and 5m, respectively, as per Elliot et al. . A flooding limit of 80% of the flooding value was imposed on all columns, and the total solvent inventory was assumed to be 150% of the summation of all equipment volumes and packing holdup. A complete list of model assumptions and equipment residence times is available in Appendix A.
