In an ammonia synthesis plant, can the process gas and ammonia be fed into the same flare?
Generally, it’s not possible; ammonia has rather special chemical properties, and it requires a relatively low Mach number to burn. Moreover, your process gas may contain acidic substances such as CO2 or H2S, which can easily lead to crystallization.
Each follows its own pipeline, converging at the torch flame.
Ammonia gas must be washed before it can enter the flare! Otherwise, the ammonia emissions will not meet the standards; there are indeed control targets in place now!
No. Generally, ammonia pipeline venting must go into a dedicated ammonia flare
There is a lot of exhaust gas consisting of pure ammonia, for example, that comes from the refrigerant in compressors; this gas is also discharged directly for combustion without any washing process

Ammonia gas must be washed in accordance with regulations; however, at present **in some places the requirements are not that strict. There are issues regarding the ammonia storage tanks used for valves, as required by the work safety supervision agency
Please provide some guidelines and terms so I can learn* from them. But I don’t think this is feasible for torches, as it’s in an accident scenario where the emission levels are extremely high, often in the tens of thousands of cubic meters; dealing with such amounts isn’t that simple.
