Raw material
1. Sulfur dioxide, SO2
Process
Purified SO2 is then oxidised by atmospheric oxygen at between 400 and 600 °C over a catalyst consisting of vanadium pentoxide (V2O5) activated with potassium oxide K2O on kieselguhr or silica support. Platinum also works very well but is too expensive and is poisoned (rendered ineffective) much more easily by impurities.
Product
Sulfur trioxide, SO3
Used for
In process plant environment, SO3 gas is mixed into flue gas from combustion to make the ashes charged up before flowing through electrostatic precipitators. The electrostatic precipitators will then trap the ashes, making cleaner process emission possible.

Export

Excellent! This is product specific. It is something I expect of a chemical engineer like you to produce. Just one thing; it would be better if you name the process to produce SO3 using this production route. I’m in fact surprise you did not mention the name of the process. It is something fundamental and I would certainly expect from an informed professional.
