L&T Energy Hydrocarbon Senior Process Engineer Interview Questions and Answers

Line sizing criteria is based on factors like flow rate, pressure drop, velocity, and material compatibility.

• Consider the flow rate of the fluid being transported

• Calculate the pressure drop allowed in the system

• Determine the velocity of the fluid to prevent erosion or corrosion

• Ensure the material of the line is compatible with the fluid being transported

Line sizing of fluids is crucial for efficient process operation and safety.

• Line sizing is determined based on the flow rate, pressure drop, and fluid properties.

• Proper line sizing ensures optimal flow velocity to prevent erosion and corrosion.

• Consider factors like viscosity, density, and temperature when sizing lines.

• Use industry standards and guidelines for accurate line sizing calculations.

• Examples: API 14E for oil ...read more

Pumps are devices used to move fluids. Types include centrifugal, positive displacement, and submersible. Cavitation is the formation of vapor bubbles in a liquid due to low pressure.

• Pumps are used to move fluids in various industrial processes.

• Types of pumps include centrifugal, positive displacement, and submersible.

• Cavitation occurs when the pressure in a liquid drops below its vapor pressure, leading to the formati...read more
