This was the question frequently asked. I feel pity for one of our friend who came for the interview. He didn't prepare. Only the first question. What do you know about MLNG ? He said "I don't know but his answer was, I am a degree holder". The interviewer said....we don't care about your degree but you must know what job and what the company is dealing about and what are you applying for. Go and do research and apply later. Very SAD. I just revealed some question for those who are interested. To help a friend if any Bidayuh might apply for this job. This site is exclusive. Don't look for taki kasung because he doesn't exist. I don't bear that name.
Q. What is MLNG as you may know?
(You are Applying MLNG. You should know about the company. What is MLNG?)
MLNG come from the word Malaysia Liquefied Natural Gas. A gas from offshore is piped to the plant(onshore), processed and liquefied to -161 degree and later transported to Customers (Japan, Korea or Taiwan) using Ships( Tenaga 1, Tenaga 2, Puteri Dilema, Amman Hakata, Aman Sendai, Puteri Intan, YK Sovereign ,Puteri Zamrud, ect...)
Q. Why do we need to liquefied Natural Gas or NG?
It is cheaper to transport Natural Gas (NG) in liquid form. By converting it to liquid, we can reduce the volume from the ratio of 600 to 1 volume. 600 volume of gas is equivalent to 1 volume of liquid LNG.

Simple SCIENCE Questions.
Q. What is Joule - Thompson (JT) effect across control valves or restrictor with respect to flow in cooling?
When there is a flow across a restrictor or control valve, there is a drop of temperature within it. The temperature effect will absorb heat from its surrounding.
Q. What is Ohm’s law?
V (voltage) =I (Current) R(Resistance)
Q. what is our Natural gas content?
It is gases taken from the ground consisting
1) Hydrocarbon gas namely methane, ethane, propane, butanes, pentane, heptanes, octane, ect.
2) Acid gas such as carbon dioxide and hydrogen sulphide
3) Water (Treated in offshore in Glycol unit)
4) And some other traces element such as nitrogen,Ferrous Iron Oxide and metals e.g. mercury.
Q. What is associated gas and non associated gas?
Associated gas = Gas coming out with heavy Hydrocarbon or condensate.
Non associate gas = Gas only.
Q. What is Acid Gas?
Acidic gas such as Carbon Dioxide (CO2) and sulphur gas( H2S). They also present in our Natural gas.
What are the four (4) most important Hydrocarbon components in making LNG?
Methane, Ethane, Propane and butane
Q. What is Pressure or do you know Pressure. Explain in words?
Pressure is a force exert on the wall. (Pressure=Force X Area)
Example: Air pressure inside a balloon.
Q. What is Dalton’s Law of partial pressure?
PV = nRT. P is directly proportional to n if V and T remain constant. As n goes up, so would P. Or the reverse
Q. What is temperature?
Degree of hotness measured in degree Celsius/degree Farenheight.
What is -375 degree K?
Lowest temperature and point the molecules are inactive. That is measured in degree Kelvin.
Q. What is the relation of pressure, Temperature and volume? Describe.
PV = nRT (as above)
If you add temperature, pressure increase in constant volume or vice versa.
Q. If you increase temperature to a fixed volume, what happened to pressure?
Q. How is the piping connected or joint?
They are bolted up with correct specification gasket in between.
Q. Running equipment such as Pumps or Compressors or other Engines. What shall be check there?

4. Meter / Ammeter reading or gauges if any.
5. No leakages
6. No wear and tear seen or bad corrosion.
7. Abnormalities such as smells
8. Any flow or not.
Q.What are the processes in MLNG or how the gas is treated?
1. Removal of slug. Liquid and gas separation in slug catcher.
2. Meter the gas intake in gas metering.
3. Gas treated using Shell’s Sulfinol Solution to remove acid gas such as carbon dioxide and hydrogen sulphide.
4. Gas is dried using 4 Armstrong molecular sieve or drier bed.
5. Cooling down using stages propane system
6. Cool down using Main cryogenic heat exchanger( 3 bundle tower)

Q.Bidayuh has a lot of land but we pity those who have no land. Why don’t you plant Oil palm or planting other crops?
We have no more land. Our kampong is all surrounded by another Kampongs leaving for us no more land. No more forest. Our entire brother/sisters are working with Chinese firm.
