Questions Related to petroleum and natural gas

The strong smelling substance added to LPG is:

  1. ethyl mercaptan

  2. ethanol

  3. ethanal

  4. ethyl butane


Correct Option: A
Explanation:

LPG gas is basically propane and butane, and it is odorless in its natural state. The smell that you notice when there is a leak is actually the stench of an entirely different agent, called ethyl mercaptan ($C _2H _6S$). This substance is added to the gas when it leaves the main storage terminals.

The chemical added to LPG to help detect its leakages is:

  1. isobutene

  2. ethylamine

  3. methyl mercaptan

  4. ethyl mercaptan


Correct Option: D
Explanation:

LPG gas is basically propane and butane, and it is odorless in its natural state. The smell that you notice when there is a leak is actually the stench of an entirely different agent, called Ethyl Mercaptan (C2H6S). This substance is added to the gas when it leaves the main storage terminals.

The main constituent of LPG is:

  1. methane

  2. butane

  3. propane

  4. both B and C


Correct Option: D
Explanation:

LPG constitutes both propane and butane in equal percentages.
Liquefied Petroleum Gas or LPG (also called Autogas) consists mainly of propane, propylene, butane, and butylene in various mixtures. It is produced as a by-product of natural gas processing and petroleum refining. The components of LPG are gases at normal temperatures and pressures.

What odorant is added to LPG to detect the leakage with smell?

  1. alcohol

  2. organo sulphur compounds

  3. coal tar

  4. chlorine gas


Correct Option: B
Explanation:

As LPG is odourless and the organo-sulphur compound has an unpleasant smell.


Hence, to detect the leakage, ethyl mercaptan (ethanethiol) is added to LPG which is an organo-sulphur compound.

Therefore, option B is correct.

  1. Where and when was the world's first oil well dug ?
  1. in 1959 AD in Pennsylvania (USA).

  2. in 1859 AD in Pennsylvania (USA).

  3. in 1849 AD in Pennsylvania (USA).

  4. in 1989 AD in Pennsylvania (USA).


Correct Option: B
Explanation:

The world's first oil well was dug in 1859 AD in Pennsylvania (USA).

___________ is added to LPG to detect leakage .

  1. Propene

  2. Hexanol

  3. Isobutane

  4. Mercaptan


Correct Option: D
Explanation:

A foul smelling chemical (mercaptan) is added to LPG to detect leakage.

Alcohol, CNG and LPG are ________ substances.

  1. gaseous

  2. inflammable

  3. inorganic

  4. none of these


Correct Option: B
Explanation:

Alcohol, CNG [Compressed Natural Gas] and LPG [Liquified Petroleum Gas] burn on ignition. So, these three elements are inflammable substances.

Natural gas is composed primarily of:

  1. Methane

  2. n-butane

  3. n-octane

  4. a mixture of octanes


Correct Option: A
Explanation:

Natural gas is composed mainly composed  of methane, but it also contains small amounts of ethane, propane, butane, and pentane. Methane, a combination of hydrogen and carbon, is formed when plants and animals (organic matter) are present  under the sedimentary layers of the earth.

Hence option A is correct.

Which of the following petroleum product is used for dry cleaning?

  2. Kerosene

  3. Diesel

  4. Petrol


Correct Option: D
Explanation:

Dry cleaning is any cleaning process for clothing and textiles using a chemical solvent other than water. Petrol is a dry cleaning agent.
