Finorchem Assistant Manager Operations Interview Questions, Process, and Tips

Draw reactor P&ID with safety equipment

• Include reactor vessel, heat exchanger, pumps, valves, and instruments

• Add safety equipment such as relief valves, pressure gauges, and emergency shutdown systems

• Label all components and connections clearly for easy understanding

HAZOP stands for Hazard and Operability Study, while PSSR stands for Pre-Startup Safety Review. They are both important processes in ensuring safety in operations.

• HAZOP is a systematic and structured approach to identifying potential hazards and operability issues in a process plant.

• PSSR is a review conducted prior to the start-up of a new or modified process to ensure that all safety systems are in place and functioni...read more

I studied various unit operations including material handling, quality control, inventory management, and process optimization.

• Material handling techniques such as batching, mixing, and packaging

• Quality control methods like statistical process control and Six Sigma

• Inventory management strategies such as ABC analysis and Just-In-Time

• Process optimization tools like Lean manufacturing and Kaizen

Types of reactors include batch, continuous stirred-tank, plug flow, and fluidized bed reactors.

• Batch reactors: operate for a fixed amount of time before being emptied

• Continuous stirred-tank reactors: have continuous flow of reactants and products

• Plug flow reactors: have perfect mixing in the axial direction

• Fluidized bed reactors: solid particles are suspended in a fluid and react with the fluid

Types of pumps include centrifugal pumps, positive displacement pumps, and axial flow pumps.

• Centrifugal pumps: use a rotating impeller to increase the pressure of a fluid.

• Positive displacement pumps: move fluid by trapping a fixed amount and forcing it through the discharge.

• Axial flow pumps: move fluid parallel to the pump shaft.

• Examples: Centrifugal pump - water pump, Positive displacement pump - diaphragm pump, Axial

The thickness of an autoclave can vary depending on the model and manufacturer.

• The thickness of an autoclave chamber typically ranges from 6mm to 12mm.

• The thickness of the autoclave walls can be influenced by factors such as pressure rating and material composition.

• Some autoclaves may have additional insulation layers to maintain temperature and pressure.

• It is important to consult the manufacturer's specifications for
