(a) Complete a steady-state simulation of the vinyl-chloride process in Figure 2.6. First, create a simulation flowsheet. Assume that:

Cooling water is heated from 30 to \(50^{\circ} \mathrm{C}\)

Saturated steam is available at \(260^{\circ} \mathrm{C}(48.4 \mathrm{~atm})\). 

If using ASPEN PLUS, use the UNIQUAC option set for thermophysical properties.

(b) Carry out process integration and repeat the steady-state simulation.
