Liquefaction plants are facilities designed to convert natural gas into a liquid form, known as liquefied natural gas (LNG). This process involves cooling the gas to extremely low temperatures, which reduces its volume significantly, making it easier to transport and store. These plants play a crucial role in the global energy market, allowing countries to export and import natural gas efficiently. By transforming gas into a liquid, liquefaction plants help meet energy demands while minimizing environmental impact during transportation.
