Chemical Engineering Interviews Questions


Material Construction question and answers

Q.1 What are the main factors to consider when selecting materials for chemical plant construction?

Key factors include chemical compatibility, mechanical strength, temperature resistance, corrosion resistance, cost, and availability. The material must withstand the operating environment and the chemicals it will come in contact with .

Q.2 Explain the significance of corrosion resistance in material selection.

Corrosion resistance is crucial to ensure the longevity and safety of equipment. Materials that resist corrosion minimize maintenance costs, prevent leaks and failures, and ensure the integrity of the chemical processes.

.

Q.3 What are some common materials used in the construction of chemical reactors? .

Common materials include stainless steel, carbon steel, glass-lined steel, and various alloys like Hastelloy and Inconel. Each material offers specific benefits in terms of corrosion resistance, mechanical strength, and temperature tolerance.


Q.4 Describe the use of stainless steel in chemical engineering.

Stainless steel is widely used due to its excellent corrosion resistance, strength, and durability. It's suitable for handling a variety of chemicals and is commonly used in piping, reactors, storage tanks, and heat exchangers.

Q.5 Why is carbon steel often used in chemical plant construction, despite its susceptibility to corrosion?

Carbon steel is chosen for its cost-effectiveness and good mechanical properties. It is often used with protective coatings or linings to mitigate corrosion in less aggressive environments.


Q.6 What are the advantages of using composite materials in chemical engineering applications?.

Composite materials, such as fiber-reinforced plastics, offer high strength-to-weight ratios, excellent corrosion resistance, and the ability to be tailored for specific applications. They are used in storage tanks, piping, and other structures where weight reduction and corrosion resistance are critical.

Q.7 How is glass-lined steel used in the chemical industry, and what are its benefits?

Glass-lined steel is used for vessels, reactors, and piping that handle highly corrosive chemicals. The glass lining provides a chemically inert and smooth surface, preventing contamination and corrosion while being easy to clean. .

Q.8 What role does thermal expansion play in the selection of materials for chemical engineering applications?.

Thermal expansion is the tendency of materials to expand when heated. Selecting materials with appropriate thermal expansion properties ensures dimensional stability and integrity of equipment under varying temperature conditions, preventing mechanical stress and potential failure.

Q.9 Explain the importance of mechanical strength in the selection of construction materials.

Mechanical strength determines a material’s ability to withstand forces and pressures during operation. It ensures the structural integrity of equipment, prevents deformation, and ensures safety and reliability under operating conditions.

Q.10 What considerations must be made when selecting materials for high-temperature applications in chemical engineering?

For high-temperature applications, materials must have high thermal stability, maintain strength at elevated temperatures, resist thermal fatigue, and prevent oxidation. Materials like stainless steels, nickel-based alloys, and ceramics are often selected for their high-temperature performance.
