Batch Reactor
A batch reactor is a type of container or vessel used in chemical manufacturing where ingredients are mixed together to create products in separate, individual batches. Think of it like a large cooking pot in an industrial setting - materials go in, are processed under controlled conditions, and the finished product comes out before the next batch begins. This is different from continuous production where materials flow through constantly. Companies use batch reactors when they need to make different products in the same equipment or when the process needs careful control of temperature, mixing, and other conditions.

Example Interview Questions
Senior Level Questions
Q: How would you improve batch reactor efficiency while maintaining product quality?
Expected Answer: A senior engineer should discuss process optimization strategies like temperature control, mixing efficiency, batch scheduling, and cleaning procedures. They should mention monitoring systems and quality control measures.
Q: How do you handle scale-up challenges in batch reactor processes?
Expected Answer: Should explain how to safely increase production volume, considering factors like heat transfer, mixing patterns, and safety protocols when moving from small to larger batches.
Mid Level Questions
Q: What safety measures do you implement when operating batch reactors?
Expected Answer: Should discuss pressure relief systems, temperature monitoring, emergency shutdown procedures, and proper handling of chemicals and materials.
Q: How do you troubleshoot common batch reactor problems?
Expected Answer: Should describe systematic approach to identifying issues like temperature control problems, mixing issues, or product quality variations, and how to resolve them.
Junior Level Questions
Q: What are the basic components of a batch reactor system?
Expected Answer: Should be able to describe main parts like the vessel, agitator, heating/cooling system, and basic control instruments.
Q: Explain the difference between batch and continuous processes.
Expected Answer: Should explain that batch processes make products in separate lots while continuous processes run non-stop, and describe basic advantages of each.
