Question: Design four separate glycol cooling system P&IDs following IChemE chemical engineering standards for a food company application using food-grade propylene glycol as a cooling medium. The four P&IDs should be individual and not combined:
- Glycol system setup including storage tank, reservoir, heat exchanger, pumps (with duty/standby), valves, instrumentation, and control loops for temperature and flow. Include electrical power lines and control signal lines.
- Glycol jacket system around a flour silo to maintain bulk flour temperature using local circulation pump and cascade temperature control loops. Include flow control, temperature sensors, interlocks, and safety devices.
- Glycol jacket system around the transfer pipework from silo to weighing hopper, showing segmented jackets with flow control valves and temperature sensors on each segment. Include thermal relief valves and instrumentation.
- Glycol jacket system around a mixer bowl used in production with internal dough temperature sensor and cascade control loops for tight temperature control. Include hygienic probe fittings, flow control valves, interlocks for flow minimums, and safety relief.
Make sure to:
Use the valve list and line list provided (attached) and integrate them into your drawings.
Add control loops best suited for temperature control based on cascade strategies from the provided information.
Include extra pumps for backup duty/standby operation in the system. Get the best assignment help from our pro-writers.
Use correct IChemE standards for line types, valve symbols, instrumentation, and control loops.
Include notes, labels, legends, and electrical power supply lines where needed.
Follow sanitary and food-grade standards for materials and fittings.
Present clear flow directions, fail-safe actions, and signal lines (pneumatic, electrical) on the P&IDs.
