Adsorption
Adsorption is a common process used in chemical and environmental industries where one substance sticks to the surface of another substance (like water vapor clinging to the surface of activated charcoal). Think of it like a sponge soaking up water, but at a molecular level. Engineers use this process to purify water, remove pollutants from air, or separate chemicals in manufacturing. It's different from absorption (where things soak all the way through) because adsorption only happens on the surface. Companies often look for engineers who understand this process because it's crucial in designing purification systems, environmental cleanup processes, and industrial separation methods.

Example Interview Questions
Senior Level Questions
Q: How would you approach scaling up an adsorption process from laboratory to industrial scale?
Expected Answer: Should explain how they consider factors like equipment size, flow rates, cost efficiency, and potential problems that might occur when increasing the scale of operations. Should mention experience with industrial-scale implementation.
Q: What factors would you consider when selecting an adsorbent material for a new process?
Expected Answer: Should discuss practical considerations like cost, effectiveness, regeneration ability, and operational conditions. Should demonstrate experience in material selection and process optimization.
Mid Level Questions
Q: Can you explain how temperature affects adsorption processes?
Expected Answer: Should be able to explain in simple terms how temperature changes impact the process, and how this knowledge is applied in real industrial situations.
Q: What methods would you use to monitor the effectiveness of an adsorption process?
Expected Answer: Should describe practical monitoring techniques and measurements used to ensure the process is working correctly and efficiently.
Junior Level Questions
Q: What is the difference between adsorption and absorption?
Expected Answer: Should be able to explain that adsorption is surface attachment while absorption involves the entire volume, using simple examples to demonstrate understanding.
Q: What are common industrial applications of adsorption?
Expected Answer: Should mention basic applications like water purification, air cleaning, or chemical separation, showing fundamental understanding of the process uses.
