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_forward
