Tata Chemicals Process Engineer Interview Questions and Answers

Design steps for a shell and tube heat exchanger

• Determine the heat duty and fluid flow rates

• Select the appropriate materials for the tubes and shell

• Determine the number of tube passes and tube layout

• Design the baffles and tube supports

• Calculate the heat transfer area and pressure drop

• Specify the inlet and outlet connections

• Prepare detailed fabrication drawings

Pressure drop in a column refers to the decrease in pressure as fluid flows through the column.

• Pressure drop is caused by frictional resistance to flow and changes in direction of the fluid.

• It can be calculated using Bernoulli's equation or by measuring pressure at different points in the column.

• Pressure drop can affect the efficiency of the column and may require adjustments to the operating conditions.

• Factors that ca...read more

Heat exchangers are devices used to transfer heat between two or more fluids.

• Shell and tube heat exchangers

• Plate heat exchangers

• Double pipe heat exchangers

• Spiral heat exchangers

• Air-cooled heat exchangers

Cooling tower is a heat rejection device that removes waste heat from a process system.

• It works on the principle of evaporative cooling

• Water is circulated through the tower and is exposed to air, which causes some of the water to evaporate

• The heat from the process system is transferred to the water, which is then released into the atmosphere

• The cooled water is then recirculated back into the process system

• The tower can...read more
