Task 1: You are tasked with developing a piping and instrumentation diagram (P\&ID) for the process described below. Waste water from an aquaculture facility is to be dosed with sodium hypochlorite solution prior to discharge to the ocean to kill off any diseases or micro organisms that might be present. Waste water from the aquaculture tanks drains under gravity into a common in-ground sump. The waste water is then pumped out of the sump under level control using a positive displacement pump with variable speed drive (VSD). The waste water flowrate is measured using a turbine style flowmeter with a check (non-return) valve downstream to prevent reverse flow (and false flow readings). Sodium hypochlorite solution (12.5\% in water) is stored in a 1,000 L intermediate bulk container (IBC) and is dosed into the waste water stream downstream of the flowmeter and check valve using a diaphragm dosing pump (variable speed) to achieve 30 ppmv chlorine in the waste water under ratio control. The chlorine content of the waste water is measured by an analyser downstream of the injection point to verify the required dosage is achieved with a low alarm set at 28 ppmv to notify the operator. The sodium hypochlorite IBC is provided with a low level switch activating a low level alarm to notify the operator when it needs refilling. The mixture of waste water and sodium hypochlorite then flows into a holding tank. The holding tank drains under level control into a dissipation pond (to allow the chlorine to dissipate from the water prior to discharge). The dissipation pond discharges treated waste water to the ocean under gravity. All piping is constructed from PVC. Wastewater piping is DN 50 in size up to the tank (pump connections are DN 40). Piping from the tank to the pond is DN80 and the pond outlet line to the ocean is DN150. The dosing pump lines are 12mm plastic tubing. Use the P\&ID Legend Sheet - Prawn Farm provided on MyUni for symbology and list it as a reference on your P\&ID. Relevant equipment data is presented below: As part of your P\&ID you are required to: 1. Name and tag all equipment and present the equipment data in an appropriate format. 2. Tag all instrumentation and lines. 3. Display all instrumentation and control functionality using the correct symbology. 4. Provide manual valving as deemed necessary for isolation and maintenance purposes and display any other required fittings. 5. Demonstrate the correct process flow. Task 2: You are tasked with developing a process description and cause and effect diagram for the process detailed on the P\&ID attached (UOFA-PS1-PID-0001-rA Stripper P\&ID). The process description should follow the process flow, include reference to parameters that are monitored vs controlled and make mention of safety functions (i.e. trips and PSV's etc.). Please refer to the P\&ID Legend Sheet - Residue Cracking Unit (refining) and use the Cause and Effect template provided.
