UPSC CSE Prelims 2005

Correct Option (b):

Statement 1 is correct.

• Liquefied Natural Gas (LNG) is produced by cooling natural gas to extremely low temperatures, typically around -162°C, at near-atmospheric pressure. This cryogenic process converts natural gas into a liquid state, significantly reducing its volume, which facilitates its efficient storage and transportation in specialized cryogenic vessels.

Statement 3 is correct.

• Natural Gas Liquids (NGL) are a group of hydrocarbons, including ethane, propane, butane, and natural gasoline, which are extracted from raw natural gas. While LPG (Liquefied Petroleum Gas) primarily consists of propane and butane, NGLs represent a broader category of products separated from natural gas. The statement implies a distinction between NGLs as a general category and LPG as a specific blend, both derived from natural gas.

Incorrect Options:

Statement 2 is incorrect.

• The first LNG terminal in India was established at Dahej, Gujarat, which became operational in 2004. It was not built in Hassan.
