Coromandel International Interview Questions, Process, and Tips

Q1. How to design heat exchanger?
Ans. 
Designing a heat exchanger involves determining heat transfer requirements, selecting appropriate materials, and optimizing the design for efficiency.
• Determine heat transfer requirements based on the fluids involved, flow rates, and temperature differentials.

• Select appropriate materials based on the compatibility with the fluids, operating temperatures, and pressure requirements.

• Optimize the design for efficiency by co...read more

Q2. What is enthalphy?
Ans. 
Enthalpy is a thermodynamic property that represents the total energy of a system, including internal energy and the amount of energy required to create or release the system.
• Enthalpy is denoted by the symbol H and is expressed in units of energy (such as Joules or calories).

• It is defined as H = U + PV, where U is the internal energy of the system, P is the pressure, and V is the volume.

• Enthalpy change (ΔH) is commonly...read more

Q2. Tell about distillation?
Ans. 
Distillation is a process of separating components of a mixture based on their boiling points.
• Distillation involves heating the mixture to vaporize the component with the lowest boiling point.

• The vapor is then condensed and collected as a separate liquid.

• This process is commonly used in the production of alcoholic beverages, petroleum refining, and purification of water.

• Fractional distillation is a variation of distill...read more

Ans. 
1. Direct vaporisation at heating surface is called? 2. Formula for steam consumption in kg/hr in an evaporator?
• 1. Direct vaporisation at heating surface is called film boiling.

• 2. Steam consumption formula: (C/E) x (LMTD/1000) x 3600

• C = capacity of evaporator, E = economy of evaporator, LMTD = log mean temperature difference
