Falling film reactor sulphonation

WebMar 28, 2007 · ABSTRACT A mathematical model is developed to simulate a falling film reactor for sulfonation/sulfation. In the model, the reaction rate is considered to be controlled by the mass transfer in the gas phase or in the liquid phase. WebFig -2: Sulfonation scheme in a falling film reactor (FFR) 4. CONCLUSIONS In the process of sulfonation with sulfuric acid or oleum the reaction mixture contains a residue of sulfuric acid. Water is a by-product of the reaction so spent acid is inevitable. This spent acid is neutralized along with the
