The reaction conversion rate is 35%. The temperature increase in heat exchanger 2 is adiabatic. A fresh stream of pure ethylbenzene (25°C) enters a mixing vessel, where it is combined with a recycle stream (from the distillation column, as explained later), which also consists of pure ethylbenzene at 25°C. After mixing, the stream is sent to a heat exchanger (HX1), where the mixture is heated to 200°C. Next, the mixture enters an adiabatic heat exchanger (HX2), where it is further heated to 300°C by adding steam (at 350°C). This steam is used to prevent side reactions and carbon deposition in the reactor. The heated mixture is then fed into the reactor, where the reaction takes place with a conversion rate of 35%. As a result, the mixture cools down to 260°C. The resulting mixture is then sent to HX4, where…arrow_forwardChemical Engineering Questionarrow_forward

The thermal decomposition of nitric oxide at elevated temperatures 2NO → N₂+02 has been studied in a batch reactor where at temperatures below 2000K the rate expression that applies to low conversions is: r = kCm05 Co At high conversions, or when the initial mixture contains a high concentration of O2 the rate expression is given by: r = k' Cм0.5 C15C0,5 To explain these kinetics the following chain reaction mechanism has been proposed: Initiation: Propagation: 2NON₂O +0 k₂ E1=272.0 kJ/mol 0+ NO O₂+ N E₂-161.0 kJ/mol N+NO N₂+0 E3-1.4 kJ/mol K4 20+ MO₂+M E4=14.0 kJ/mol ks Termination: where M is any molecule capable of the energy transfer necessary to stabilize the oxygen molecule. Once appreciable amounts of O2 are present in the reaction mixture, the initiation reaction that is the primary source of atomic oxygen is no longer the first reaction.
