What is the typical production rate for double-pressurized platinum nitrate mesh?

In actual production, what is the typical production rate for platinum mesh in dual-pressure nitric acid plants?
The consumption of platinum nitrate mesh under double-pressure conditions is around 100–120 mg, and this is closely related to the factory’s operational management level
Expert upstairs: What you are referring to is the consumption of platinum mesh, while my question concerns the production rate of platinum mesh – the two are different things.
The production intensity of platinum mesh in double-pressure nitric acid plants is generally 900–1500 kg NH3/d·m2
Typical platinum mesh has a strength of 343 MPa, with a force of around 3,000 kilograms
The “strength” referred to by the resident on the 5th floor is mechanical strength, whereas what the original poster is talking about is production capacity – they are two completely different concepts.
The production capacity of the platinum mesh in double-pressure nitric acid plants is generally 900–1500 kgNH3/d·m2. In our old plant, which operates at atmospheric pressure, the production capacity is around 800 kgNH3. The new plant, designed using pressurized methods, is intended to achieve a production capacity of 1100 kgNH3. It’s still in the adjustment phase; if things proceed at the same pace as in the old factory, it shouldn’t be a problem to reach 1400 kg in the future
What are the reasons for the increased production efficiency of the new platinum mesh device?
Reply to 8# lxq700918: The new factory site uses the double-pressure method. In this method, the oxidation furnace is equipped with more layers of platinum mesh; therefore, even with an increased amount of ammonia used, the oxidation rate can still meet the production requirements. The only downside is that more platinum is consumed. But at normal pressure it doesn’t work; the platinum mesh in the oxidation furnace using normal-pressure methods consists of only three layers. If too much ammonia is used, the strength of the platinum mesh is not sufficient, resulting in high losses of platinum. Moreover, the oxidation rate does not meet the production requirements, and there are significant losses of ammonia, which makes it uneconomical.
