Discuss whether the tower wall temperature in the CO2 gas synthesis tower increases from bottom to top?
Inside the synthesis tower, about 20% of the ammonia and carbon dioxide continue to react; the heat released by this reaction is 119.2 kJ/mol. The reaction involving the dehydration of methylammonium to form urea is endothermic, with the dehydration of liquid NH4COONH2 absorbing 15.5 kJ/mol of heat. It is evident that the heat released during the formation of methylammonium is much greater than the heat absorbed during the formation of urea through dehydration; therefore, the temperature increases gradually from bottom to top
