Estimate the quantities and yearly costs of the appropriate utilities for the following pieces of equipment on the toluene hydrodealkylation PFD (Figure 1.5). It is assumed that the stream factor is 0.95 and that all the numbers on the PFD are on a stream time basis. The duty on all of the units can be found in Table 1.7.

1. E-101, Feed Preheater

2. E-102, Reactor Effluent Cooler

3. H-101, Heater

4. C-101, Recycle Gas Compressor, assuming electric drive

5. C-101, Recycle Gas Compressor, assuming steam drive using 10 barg steam discharging to atmospheric pressure

6. P-101, Toluene Feed Pump
