Problems have arisen in the Aspen simulation of the natural gas desulfurization process

During the simulation of using MDEA to absorb in the Aspen process, problems arose with the cycle structure of the desorption tower. How should this be adjusted? Block: R102 Model: RADFRAC * WARNING: Reactive flash failure inside the loop. RMSERR = 5.7523D-04; RMSERR outside the loop = 4.2711D-05. Information: Reactive flash failure inside the loop – RMSERR = 2.5787-03; RMSERR outside the loop = 2.9432D-05. The composite feed flash failed to converge; column calculations continue. If the calculations fail, perform a supply T-test, and optionally also a X-est and Y-est test. No errors occurred during simulation when no loops were used, but problems arose as soon as loops were incorporated. I would appreciate it if the experts here could give some advice
