What is the effect of the ammonia-to-carbon ratio on the top and bottom temperatures of the synthesis tower?
Thread Content
What is the relationship between the ammonia-to-carbon ratio in the carbon dioxide stripping process (vertical high-pressure ammonium methoxide condenser) and the temperatures at the top and bottom of the synthesis tower?
The reflected temperature in the synthesis tower is the ammonia-to-carbon ratio at the highest temperature; regardless of whether this ratio is high or low, the temperature will decrease
2.2.3.1 Control of temperature in the synthesis tower (201-D) (gas phase TI-208, liquid phase TI-217). Control range: TI-208 180-185℃； TI-217: Control range of 180–185°C; target accuracy: not more than ±1°C. Relevant parameters: NH3/CO2, H2O/CO2, system pressure PI-201, low-pressure steam pressure PIC-915, and heating steam pressure at 201-C PIC-918. Control method: Manual adjustment. Normal adjustment: Influencing factors and adjustment methods – For NH3/CO2: If the levels of NH3/CO2 are too high, TI-217 and TI-208 will decrease; if these values fall below the specified range, it is necessary to accurately assess the situation and appropriately reduce the amount of ammonia in the system. 2. When NH3/CO2 levels are too low, TI-217 and TI-208 increase; if these values exceed the specified limits, it is necessary to make an accurate assessment and appropriately increase the ammonia level in the system. A comprehensive judgment is needed.
