Coal to ammonia, medium-low temperature shift process
Thread Content
In coal-based ammonia synthesis, with medium and low temperature shift processes, have you encountered such a situation? The carbon monoxide level at the low-temperature outlet is high, but other parameters such as hot water flow rate, steam ratio, hotspot temperature, and pressure are all normal. It’s just the high carbon monoxide level at the outlet – what could be causing this? I’ve been using this low-voltage version for about 6 years; it’s the B303 model. Thank you!
Check if it’s a gauge issue; has it been resolved now?
Check for any leaks in the system, and measure the CO content in each section of the converter
Instrument monitoring, imported CO content, CO content at the middle-stage outlet, adjustment of the gas-to-vapor ratio, determination of whether the catalyst is deactivated, and increase in the catalyst’s hot spot temperature. Check for leaks in the gas composition of the inlet and outlet gases of the heat exchanger.
