I applied via Walk-in and was interviewed in Oct 2022. There were 3 interview rounds.
Line sizing is calculated based on the flow rate, pressure drop, and fluid properties.
Determine the required flow rate for the process
Calculate the pressure drop based on the length of the line and the fluid properties
Select a pipe size that can handle the required flow rate and pressure drop
Consider factors such as corrosion, erosion, and velocity limitations
Use industry standards and guidelines for pipe sizing

Relief valves are of two types - pressure relief valves and safety relief valves. Their size is calculated based on the flow rate and pressure.
Pressure relief valves are used to protect equipment from overpressure and are typically set at a specific pressure level.
Safety relief valves are used as a last line of defense and are typically set at a higher pressure level than pressure relief valves.
The size of a relief val...
NPSH Available is the amount of fluid pressure available at the suction of a pump.
NPSH Available is the difference between the absolute pressure at the suction of the pump and the vapor pressure of the fluid being pumped.
It is important to ensure that the NPSH Available is greater than the NPSH Required for the pump to avoid cavitation.
NPSH Available can be increased by increasing the pressure at the suction of the pum...
Cavitation in pumps can be troubleshooted by identifying the root cause and taking corrective actions.
Check for low suction pressure or high discharge pressure
Inspect the impeller and casing for damage or wear
Ensure proper alignment of the pump and motor
Verify that the pump is properly primed
Consider changing the pump design or increasing the size of the suction pipe
Install a cavitation eliminator or inducer
Monitor the...

I applied via Company Website and was interviewed before Feb 2023. There was 1 interview round.
The overall refinery setup typically includes crude oil distillation units, catalytic cracking units, hydrotreating units, and various other processing units.
Crude oil distillation units separate crude oil into different fractions based on boiling points
Catalytic cracking units break down heavy hydrocarbons into lighter products like gasoline and diesel
Hydrotreating units remove impurities like sulfur from products to ...
I applied via Indeed and was interviewed in Sep 2023. There were 2 interview rounds.

Desalination is the process of removing salt and other minerals from seawater to make it suitable for drinking or irrigation.
Desalination can be done through processes like reverse osmosis, distillation, and electrodialysis.
Countries with limited freshwater resources, like Saudi Arabia and Israel, heavily rely on desalination plants.
Desalination can be energy-intensive and expensive, but advancements in technology are
