1 Description Tubular reactors are continuously operated reactors. Tubular reactors make possible the cost-effective production of large product quantities with consistent quality. The main component of it is the tubular reactor with ten temperature-controlled sections. Two pumps convey the reactants from the receiving tanks into the preheating sections and then into the reactor. The preheating sections consist of a coiled tube located in the hot water tank. After preheating, the reactants are mixed just before they enter the reactor. The electrical conductivity of the reaction mixture is measured at the inlet, in the centre and at the outlet of the reactor. While the reaction mixture flows through the reactor, the reactants react to the products. The mixture of products and unreacted reactants leaves the reactor and is collected in a tank. The volumetric flow rates of the reactants and thus also the retention time in the tubular reactor are adjusted at the pumps. The ten sections of the tubular reactor consist of tubular heat exchangers. The reaction mixture flows in the inner tube of the heat exchanger and the hot water flows in the outer tube. This hot water circuit is temperature controlled. The controller on the switch cabinet makes it possible to set the desired temperature and displays the current temperature in the hot water tank. Three stirring machines ensure uniform mixing and temperature distribution in the reactant tanks and in the hot water tank. Sensors record the temperatures and electrical conductivities. The measured values are read from digital displays and can be transmitted simultaneously via USB directly to a PC where they can be analysed using the software. The reaction is analysed using the measured electrical conductivities and the conversion rate calculated from this. 2 Specification continuous tubular reactor to carry out a saponification reaction 10 tubular heat exchangers as reactor 2 identical pumps to convey the reactants adjustment of the volumetric flow rates of the reactants at the pumps preheating of the reactants with 2 stainless steel coiled tubes T-piece for mixing the preheated reactants measurements for electrical conductivity: at the inlet, centre and at the outlet of the reactor hot water tank with temperature control measurement of conductivity and temperature with 3 combined sensors software for data acquisition via USB under Windows 8.1, 10 3 Technical data Tubular reactor Ø inner: approx. 8mm reactor volume: approx. 0,5L material: 1.4571 Reactant pump max. flow rate: 0,3L/min max. head: 20m Tanks reactants: 2x 25L products: 1x 50L water: 1x 30L Hot water circuit heater power: approx. 4kW temperature: max. 55°C Stirring machines speed: max. 310min-1 Measuring ranges volumetric flow rate: 2x 2…320mL/min temperature: 4x 0…80°C conductivity: 3x 0…100mS/cm 400V, 50Hz, 3 phases 400V, 60Hz, 3 phases, 230V, 60Hz, 3 phases UL/CSA optional Dimensions and weight LxWxH: 1900x790x1950mm Weight: approx. 250kg Required for operation Ethyl acetate, caustic soda (for saponification reaction) PC with Windows recommended
