Hi smyk,

Reaction of SO3 with water seems instanteneous evolving great heat of reaction. So, the most part of the SO3 shall be absorbed in Oleum or c-Sulfurcid Acid intead of water. The sulfuric acid can be produced by diluting the SO3- or H2SO4-rich fluids with water.

The plant capacity is not small at all. Quite limited data are available in generic domain, so why not refer to the major licensors such as Monsanto Enviro-Chem etc.?
