Given a reaction mechanism involving multiple steps and species, with known kinetic parameters and thermodynamic properties, design a plug-flow reactor system that minimizes capital and operating costs while achieving a target conversion of 90% and selectivity of 95%, considering constraints on pressure, temperature, and catalyst deactivation, and provide a detailed CAD drawing and equipment list, assuming a feed rate of 100 kg/h and a reactor volume of 10 m^3.

Analyze a recent process upset event where the reactor temperature deviated by 10°C from setpoint, resulting in a 20% decrease in yield, and identify the root cause of the upset by examining historical data on feed composition, flow rates, and equipment performance, and provide a detailed report including a fishbone diagram, a list of potential contributing factors, and recommendations for preventative measures, assuming the process is controlled by a PID algorithm with a sampling period of 1 minute.

Optimize the design and operation of a distillation column to separate a binary mixture with a relative volatility of 1.5, given a feed flow rate of 500 kg/h, a feed composition of 50% each component, and a desired purity of 99% for both products, considering constraints on column height, diameter, and reflux ratio, and provide a detailed column design and operating procedure, including a McCabe-Thiele diagram and a calculation of the minimum reflux ratio.

Design a control strategy for a chemical process involving multiple unit operations, including reaction, separation, and purification, to regulate key process variables such as temperature, pressure, and flow rate, and ensure stable operation and optimal performance, considering constraints on equipment capacity, energy consumption, and product quality, and provide a detailed description of the control architecture, including a P&ID diagram, a list of control loops, and a discussion of potential control strategies, assuming a decentralized control system with a sampling period of 10 seconds.
