Problems with gas diversion in the ammonia synthesis process transformation
Thread Content
In the ammonia synthesis process, during the conversion of gas flow, one of the converters is used for warming the pipes; there are no temperature and pressure gauges in front of the inlet valve of that converter. How can one determine whether the pipe warming process is complete?； Are there any requirements for the load air volume in terms of transformed gas guidance?
How is it possible that there’s no design table, but voltage transformers are always present? Otherwise, how could emptying be carried out? Wait until the draining is complete and all the liquid has flowed to the area in front of and behind the inlet valve, then take a temperature reading using a handheld thermometer on site. . . . .
There should be temperature measurement points from the gasification stage to the single-stage furnace; without temperature data, it’s impossible to control the temperature entering the furnace
I don’t understand what you mean. Before introducing gas, shouldn’t one first replace the air, ensure airtightness, and raise the temperature? Once these conditions are met, gas can be introduced. If steam is used to warm the pipes, it’s sufficient that the steam contains no water. Specifically, it is related to the actual conditions of the device, catalysts, etc.
Just use a temperature gun to check at the outlet, or remove the insulation and attach a surface thermometer.
There must be a thermometer at the inlet of the first converter; otherwise, how can the temperature at that inlet be controlled? A temperature gun can be used to measure the temperature of the drain valve flange.
Backflow generally occurs only during startup and shutdown; the pressure can be kept under control. The temperature can also be checked using a thermometer – as long as it is above the steam dew point, there should be no water present. In many cases, experience-based methods can also be used instead.
