The following error is displayed during operation – how to resolve it? Block: T1202 Model: RADFRAC *** SEVERE ERROR: A liquid feed/pump circuit around the top stage is required when “Q1=0” is specified in “COL-SPECS”; the required feed/pump circuit has zero flow. * WARNING: The rest of the block has been bypassed due to this severe error.

There needs to be a liquid-phase stream at the top of the absorption tower; if it’s not a problem with the settings, it might be caused by a value of 0 for the material at the tower top in the circulation calculations
