Calculation of total catalyst loading
Thread Content
For a 3+2 two-stage conversion and two-stage absorption system, what should be the total amount of catalyst loaded? What is the basis for the calculation?
What is the scale of the facility? Imported or domestic catalyst? There’s no data provided – how can it be calculated?
The amount of catalyst loaded is generally calculated based on the required reaction time or space velocity.
On a quantitative basis, factors such as the scale of the sulfuric acid system, the acid production process used, the sulfur dioxide concentration, and the manufacturer of the catalyst all affect the loading amount, which needs to be considered comprehensively.
It needs to be determined by taking into account both the design and the actual process conditions; furthermore, the loading amount of catalysts varies between domestic and foreign applications.
Gas concentration: 8%, converter diameter: 6.8 meters, raw material grade: 46%, annual output of standard acid: 130,000 tons. Please help and provide the calculation result. There is insufficient data; it will be supplemented as soon as it is suggested by everyone. Thank you.
Catalysts are generally evaluated based on their acid production rate per day: domestic catalysts produce 280 L/T, while imported catalysts produce 220 L/T. It is also possible to consult the catalyst manufacturers for more details. The catalyst life is generally 0.15 liters per ton of acid produced.
The catalyst consumption is too high; 0.05 liters per meal is quite a lot
