$($v$)$ Caustic soda solution: $5$ wt percent NaOH,$293K$

$($v$)$ Electricity: $440V,50Hz,3$ phase

Scope of design work required

$(1)$ Prrocess Design

$($a$)$ Prepare material balance for the process including an analysis of each reactor stage On stream time may be taken as $330$days per year.

$($b$)$ Prepare energy balance for the $1^{st}$ reactor and for the chlorobenzene column $($take the reflux ratio for the column as twice the minimum reflux ratio$).$

$($c$)$ Prepare a process flow diagram for the plant. This should show the major items of equipment with an indication of the materials of construction and of the internal layout. Temperature and pressure should be included.

$(2)$ Chemical Engineering Design

Prepare a sieve column design for the chlorobenzene distillation and make dimensioned sketcheds showing details of the plate layout including the weire and the downcomer.

$(3)$ Mechanical Design

Prepare a mechanical design of the chlorobenzene column estimating the shell thickness, the position and sizes of all nozzles and method of support for the for the plates and the column shell. Make a dimensional sketch suitable for submission to a drawing office.

$(4)$ Safety

Indicate the safety measures required for the plant, bearing in mind the toxic and inflammable materials handled.
