Spentex Industries Engineer Trainee Interview Questions and Answers

Ammonia is produced through the Haber process, which involves reacting nitrogen and hydrogen at high temperature and pressure.

• Nitrogen and hydrogen are reacted in a 1:3 ratio

• The reaction is catalyzed by iron

• The process is carried out at high temperature (400-500°C) and high pressure (200-400 atm)

• Ammonia is formed as a gas and can be liquefied for storage and transportation

DM plant process involves removal of impurities from water using ion exchange process. Parameters include flow rate, pH, conductivity, etc.

• DM plant stands for Deionization plant

• Water passes through ion exchange resin beds to remove impurities

• Parameters to monitor include flow rate, pH level, conductivity, pressure, temperature

• Regular regeneration of resin beds is necessary for efficient operation

Urea plant process involves distillation feed with specific parameters and number of plates.

• Urea plant process includes synthesis of ammonia and carbon dioxide to produce urea.

• Distillation feed in urea plant is typically a mixture of urea, water, and other byproducts.

• The number of plates in distillation column depends on the desired purity of urea product.

• Efficient separation of urea from impurities is crucial for high

The type of compressor used determines the height of the piling tower.

• The height of the piling tower will vary based on the type of compressor being used.

• For example, a centrifugal compressor may require a taller piling tower compared to a reciprocating compressor.

• Factors such as the volume of air being compressed and the pressure requirements will also impact the tower height.

The type of conveyor used for transporting neem coated urea solution can vary depending on the specific requirements of the application.

• Conveyors commonly used for transporting liquids include belt conveyors, screw conveyors, and pneumatic conveyors.

• Neem coated urea solution may require a conveyor with special lining or material to prevent corrosion or contamination.

• The choice of conveyor will depend on factors such as...read more
