IFFCO Chemical Engineer Interview Questions and Answers

Pump power is calculated using the affinity law, heat exchanger design involves Kern method, and column diameter changes under pressure and vacuum.

• Pump power is calculated using the affinity law formula: P2/P1 = (N2/N1)^3 * (D2/D1)^5

• Heat exchanger design involves using the Kern method to determine the heat transfer area and overall heat transfer coefficient

• Types of heat exchangers include shell and tube, plate heat exc...read more

Yes, I have experience in commissioning chemical projects.

• I have worked on commissioning a chemical plant for a new production line

• I was involved in the startup and testing of equipment to ensure proper functioning

• I collaborated with a team of engineers to troubleshoot any issues that arose during commissioning

Euler's equation is a mathematical formula that relates the values of trigonometric functions to complex exponential functions.

• Euler's equation is e^(ix) = cos(x) + i*sin(x)

• It is used in various fields including physics, engineering, and signal processing

• It is named after the Swiss mathematician Leonhard Euler

Law of motion is a fundamental concept in physics that describes the behavior of objects in motion.

• There are three laws of motion formulated by Sir Isaac Newton.

• The first law states that an object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity, unless acted upon by a net external force.

• The second law states that the acceleration of an object is directly proportional ...read more

PID stands for Proportional-Integral-Derivative, a control loop feedback mechanism used in industrial processes to maintain desired setpoints.

• PID is a control algorithm that calculates an error value as the difference between a desired setpoint and a measured process variable.

• The PID controller then adjusts the process control inputs to minimize the error and keep the process variable close to the setpoint.

• The Proporti...read more

A thermowell in a tank is a protective device used to shield temperature sensors from the harsh environment inside the tank.

• Thermowells are typically made of metal and are inserted into the tank to provide a sealed chamber for the temperature sensor.

• They help protect the sensor from corrosion, pressure, and other damaging factors inside the tank.

• Thermowells also allow for easy removal and replacement of the temperature...read more
