Error: RADFRAC did not converge within 25 outer loop iterations. **The error: The subcooling temperature specified in the “SC-REFLUX” statement (345.15) is greater than the saturation temperature in Phase 1 (331.47); the final result assumes that the reflux is in liquid form under the specified conditions. ERROR: RADFRAC did not converge after 25 iterations of the outer loop. ** ERROR: The subcooled temperature specified in the “SC-REFLUX” statement (345.15) is higher than the saturation temperature for Stage 1 (331.47); the final results assume that the liquid is in a reflux state under the specified conditions.
