Gas liquefaction is the process of converting a gas into a liquid state by applying pressure and lowering the temperature. This transformation is essential for transporting and storing gases like natural gas more efficiently. When gases are liquefied, they occupy significantly less volume, making it easier to handle and move them. The liquefaction process typically involves cooling the gas using refrigeration cycles or expansion methods. Once the gas is cooled to its liquefaction point, it can be stored in specialized containers. This technology is crucial for industries that rely on liquefied natural gas (LNG) for energy and other applications.
