Commissioning Field Operator Interview Questions and Answers
Q1. How to monitor delta D on steam line?
Delta D on steam line can be monitored using differential pressure transmitter.
Install a differential pressure transmitter across the steam line.
Calibrate the transmitter to measure the pressure difference between two points.
Convert the pressure difference to delta D using the known properties of the fluid.
Monitor the delta D reading regularly to detect any changes in the steam line.
Take corrective actions if the delta D reading exceeds the acceptable limit.
Q2. what is saturated steam?
Saturated steam is steam that is in equilibrium with liquid water at the same temperature and pressure.
Saturated steam is commonly used in industrial processes for heating and sterilization.
It is often produced by boiling water in a closed vessel, such as a boiler.
Saturated steam has a high heat content and can transfer heat efficiently.
It is important to control the quality of saturated steam to prevent damage to equipment and ensure safety.
Saturated steam is often used in p...read more

Q7. Give a Ejector working principle?
An ejector works on the principle of converting pressure energy into velocity energy to create a vacuum.
An ejector consists of a motive fluid nozzle, a suction chamber, and a diffuser.
The motive fluid, usually a high-pressure gas or liquid, is forced through the nozzle, creating a high-velocity jet.
This high-velocity jet entrains and mixes with the suction fluid, which could be a gas or liquid at a lower pressure.
The mixing of the motive and suction fluids results in an incre...read more
Q8. What is absorbtion?
Absorption is the process by which one substance is taken in or incorporated into another.
Absorption occurs when a substance is absorbed or soaked up by another substance.
It is a common process in various fields such as chemistry, biology, and physics.
In chemistry, absorption refers to the process of a substance being dissolved or taken up by another substance.
In biology, absorption refers to the process by which nutrients from food are taken up by the body.
In physics, absorp...read more
