Trains of reactors with interstage

Figure 8-S shows the temperature-conversion trajectory for a train of reactors with interstage heating. Now consider replacing the interstage heating with injection of the feed stream in three equal portions as shown below ...

The subsequent step, the epoxidation of propylene by EBHP, is carried out in the liquid phase over a proprietary heterogeneous catalyst, to produce crude PO and MPC. The feed to the reactors consists of make-up and recycle propylene and EBHP in EB. The reaction train consists of a number of adiabatic fixed bed reactors with interstage cooling. Deactivated catalyst is replaced, incinerated to remove residual hydrocarbons, and dispersed in a landfill.
