Which device converts LNG from liquid to gas by adding heat?

The process of converting liquefied natural gas (LNG) back into its gaseous form is achieved through the use of a vaporizer. A vaporizer adds heat to the LNG, allowing it to change from a liquid state to a gas. This is particularly important during the distribution and utilization of natural gas, as it allows the LNG, which is stored in a cryogenic liquid state, to be transformed into a gas that can be used for combustion or other applications.

The function of the vaporizer is critical because it facilitates the safe handling and delivery of natural gas at the required pressure and temperature conditions. As the LNG absorbs heat from its surroundings or through mechanical means, it vaporizes, enabling the gas to flow through pipelines and be utilized in various sectors such as transportation, residential heating, and industrial applications.

Other devices mentioned, like compressors, pressure regulators, and heat exchangers, play different roles in the handling and management of gases and liquids but are not primarily responsible for converting LNG from liquid to gas. Compressors typically increase the pressure of the gas, pressure regulators control the flow and pressure of gas in pipelines, while heat exchangers transfer heat between fluids without mixing them, rather than directly converting states of matter.
