The production of ethylbenzene is described in Appendix B, Project B.2. From the PFD (Figure B.2.1) and accompanying stream table (Table B.2.1), determine the following:

1. The single-pass conversion of benzene

2. The single-pass conversion of ethylene

3. Overall conversion of benzene

4. Overall conversion of ethylene

Suggest two strategies to increase the overall conversion of ethylene and discuss their merits.
