Process Science                                               

In this section the final chosen design of process for the plant is explained. This involves an overview of the plant diagram, which is done in conjunction and reference to the PID. Each line present is analysed and its constitution explained. This is also
done for each major piece of equipment with a corresponding design methodology presented for the respective piece. For each of these pieces there is also a sub-section detailing the approach that was taken to arrive at the final design with any calculations
required presented and justified.

Plant Overview

This is a systematic run through of the process flow diagram providing the methodology behind the design while also providing the compositions and flow rates throughout each pipe and vessel through the system. It also details the design specifications of
the vessels, reactors and pumps.

T002 is a storage tank for the beet molasses with a volume of 60m³. This volume allows for storage of up to 3 days worth of beet molasses. The flow from this tank, stream 1, is at a rate of 0.82m³/hr. This flow goes through the reciprocating
pump, P103, which takes it to a mixing vessel, M001. The viscosity of this flow is very high and in the range of 4.4Pa.s. The tank T001 is a storage tank for the sugar cane molasses and has a volume of 20m³, which also accommodates for a
3 day supply.

The flow from this tank, stream 1, is at a rate of 0.21m³/hr. This similarly goes through a reciprocating
pump, P101, due to the high viscosity of the flow, to M001. T003 is the storage tank for the mixing water. This flow, with µ equal to 1.15×10^-3 at 15°C, can be pumped through stream 6 via a centrifugal pump, P105, to M001.

The supply of the mixing water is at a rate of 1.22m³/hr. The temperature of the substances in all of these tanks and through each respective pipe is assumed to be that of the surroundings temperature. This is assumed to be an average throughout
the year of 15°C.
