The authors wish to correct Table A1 of the published paper in Processes []. Flow values were reported instead of temperature and pressure values. The correct version of Table A1 is given on the following page. We apologize for any inconvenience caused to readers of Processes by this change.

Table A1. The stream data for the methanol to olefins (MTO) process.
