The nozzle reactors are 0.55 x 10¯³ m³ 1.52 x 10¯³ m³ and 5.13 x 10¯³ m³ respectively, and flow visualizations have been studied by injecting a tracer into the inlet and at the walls of the reactors.

Fast reactions studies involving aqueous solut­ions of sodium carbonate (Na₂Co₂) and sulphuric acid (H₂SO₄) were carried out at varying molar ratios and flow rates in 0.55 x 10¯³ m³ and 5.13 x 10¯³ m³ nozzle reactors respectively. The product samples were determined volumetrically; the yield of the product and the amount of the excess acid reacted in each reactor were determined from stiochiometry. A modified residence time distribu­tion model was developed with the designed equations for a CSTR and plug flow to determine the conversion of the limiting reactant concentration. Neutralization reaction was carried out involv­ing Linear alkyl sulphonic acid (Dodecylbenzene sulphonic acid) with aqueous solution of sodium carbonate and at varying viscosity of the surfactant in 0.55 x 10¯³ m³ nozzle reactor. Studies were conducted at varying flow rates of Dobanic acid and sodium carbonate, and the percentage of the active detergent was analyzed volumetrically.","abstract_html":"A study of fast reactions in three nozzle reactors of the same geometry has been investigated.
