HYOSUNG CORPORATION Trainee Interview Questions and Answers

Q1. What is the operating law of a centrifugal pump?
Ans. 
The operating law of a centrifugal pump is based on the principle of converting mechanical energy into fluid energy.
• Centrifugal pumps work by using a rotating impeller to increase the velocity of the fluid, which is then converted into pressure energy.

• The pump operates based on the principle of centrifugal force, where the rotating impeller creates a centrifugal force that pushes the fluid towards the outer edges of th...read more

Q1. What do you mean by electrical electric current
Ans. 
Electric current is the flow of electric charge in a conductor.
• Electric current is the rate of flow of electric charge.

• It is measured in units of amperes (A).

• Electric current can be either direct current (DC) or alternating current (AC).

• DC flows in one direction while AC periodically changes direction.

• Examples of electric current include the flow of electrons in a wire and the movement of ions in an electrolyte solutio

Q1. Normal plant process of ammonia
Ans. 
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

Q2. Normal DM plant process and perameter
Ans. 
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

Q3. Urea plant process and perameter distillation feed number of plat
Ans. 
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

Q4. Type of compressor pirling tower height
Ans. 
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.
