Chemfab Alkalis Interview Questions, Process, and Tips

Efficiency of heat exchanger can be found by calculating the heat transfer rate and comparing it with the maximum possible heat transfer rate.

• Calculate the heat transfer rate using the formula Q = U*A*ΔTlm, where U is the overall heat transfer coefficient, A is the heat transfer area, and ΔTlm is the log mean temperature difference.

• Calculate the maximum possible heat transfer rate using the formula Qmax = m*Cp*ΔT, wher...read more

Interlocks and flare systems are crucial for safety in process engineering.

• Flare systems are used to safely dispose of excess or dangerous gases.

• Interlocks and flare systems work together to prevent accidents and protect personnel.

• Examples of interlocks include pressure switches, temperature sensors, and flow meters.

• Examples of flare systems include...read more

A level transmitter measures the level of liquids or solids in a container using various principles like hydrostatic pressure or capacitance.

• Hydrostatic Pressure: Measures pressure at the bottom of a tank to determine liquid level.

• Capacitance: Uses changes in capacitance between probes to measure level.

• Ultrasonic: Sends ultrasonic waves to the surface and measures the time taken for the echo to return.

• Radar: Uses micro...read more

A single line diagram (SLD) is a simplified representation of an electrical system showing components and their connections.
