Film reactor for a gas-liquid, in particular a sulfonation, or sulfatation, reaction

A continuous falling film reactor to obtain a product through a gas-liquid, in particular a sulfonation, or sulfatation, reaction, between a first reagent, in particular in the liquid phase, especially in the form of an organic raw material, and a second reagent, in particular in the gaseous phase, especially in the form of sulphuric anhydride, i.e., of diluted sulphuric anhydride, preferably diluted with air;

• the reactor comprising a reactor body, or outer shell, adapted to house a plurality of chambers, in particular elongated and/or tubular chambers, for a reaction between said first reagent and said second reagent;
• said chambers, in particular elongated and/or tubular reaction chambers having a respective inner surface, in particular for the sliding of said first reagent in the form of a thin film, or layer, introduction means of said first reagent, in particular in the liquid phase, especially in the form of an organic raw material, into said chambers, in particular elongated and/or tubular reaction chambers, and introduction means of said second reagent, in particular in the gaseous phase, especially in the form of sulphuric anhydride, in the respective, in particular elongated and/or tubular, reaction chamber;
• means, or head being provided for the introduction of said first reagent, in particular in the liquid phase, especially in the form of an organic raw material, in the respective, in particular elongated and/or tubular, reaction chamber;
• wherein said means, or head, for the inlet of said first reagent, in particular in the liquid phase, especially in the form of an organic raw material, in the respective, in particular elongated and/or tubular, reaction chamber, comprise, or comprises, corresponding nozzle means, in particular, radially extending nozzle means, for the passage of said first reagent, or organic raw material, in particular a fluid, preferably liquid raw material, towards the respective, in particular elongated and/or tubular, reaction chamber;
• and wherein said nozzle means are in the form of said nozzle means calibrated so as to cause a predetermined load loss of said first reagent, in particular in the liquid phase, especially in the form of an organic raw material, feeding towards the respective, in particular elongated and/or tubular, reaction chamber, and such as to ensure a controlled, in particular a constant or substantially constant, flow rate, of said first reagent, in particular in the liquid phase, especially in the form of an organic raw material, entering the respective, in particular elongated and/or tubular, reaction chamber, and so as to evenly distribute said first reagent, in particular in the liquid phase, especially in the form of an organic raw material, on the respective inner surface thereof.
