Why does the bed temperature in the diol synthesis tower show uneven distribution, and how can this be addressed? The ammonia washing tower discharges dirty wastewater with a high ammonia content, which leads to uneven temperature distribution. ② High levels of CO and CO2 at the inlet, along with a high methanol load, also cause uneven temperature distribution. ③ An unsuitable gas composition in the system can affect the bed temperature and lead to uneven distribution. Solutions: ① Increase wastewater discharge, conduct analyses, and coordinate with the control team to address issues related to carbonization and ammonia leakage. ② Reduce the levels of CO and CO2, and use the electric furnace to stabilize the temperature. ③ Operate the electric furnace carefully to gradually restore temperature stability.
