Erratum: Techno-economic analysis and performance comparison of aqueous deep eutectic solvent and other physical absorbents for biogas upgrading (Applied Energy (2018) 225 (437–447), (S0306261918306809) (10.1016/j.apenergy.2018.04.112))

The authors regret to inform that there are errors in the vertical axis of Figs. 4 and 5 as well as corresponding text. The corrected versions are given below. (Figure presented.) Fig. 4b: the left y-axis should read “$·Nm^-3 CH₄” instead of “k$·Nm^-3 CH₄”; The corrected version of Fig. 5 is shown below. Abstract: The text at the end of Abstract: ‘For the case with …respectively’ should read: “…with AQ_50wt.%DES and PC decrease by…” instead of “…with PC and AQ_50wt.%DES decrease by…” Section 3.3.2: The text at the end of paragraph 5: ‘The results of specific TAC of using…than that using water, respectively. ’ should read: “…using AQ_50wt.%DES and PC decrease by ….” instead of “…using PC and AQ_DES decrease by…” “…using AQ_50wt.%DES and PC increase up to…” instead of “…using PC and AQ_50wt.%DES increase up to…” The text at the end of paragraph 6: ‘While, using…raw biogas capacity. ’ should read: “…and 25% than water…” instead of “…and 50% than water…” Conclusion: The text at the end of paragraph 2: ‘The results of specific TAC of using PC …than PC should be developed.’ should read: “…using AQ_50wt.%DES and PC decrease by…” instead of “…using PC and AQ_50wt.%DES decrease by…” “…using AQ_50wt.%DES and PC treated with…” instead of “…using PC and AQ_50wt.%DES treated with…” The above errors do not reflect any calculations errors and do not compromise the findings of the paper. The authors would like to apologize for any inconvenience caused.
