Facilities for floating liquefied natural gas (FLNG) production, liquefaction, and storage offer an innovative method of doing so. These offshore platforms offer flexibility in accessing remote gas reserves because they are built to process natural gas at sea. Heat exchangers are an essential part of FLNG systems and are essential to the liquefaction process. The principles of heat exchanger design for FLNG, taking into account the particular difficulties and requirements that these cutting-edge offshore installations present.

Understanding the FLNG Process

In essence, FLNG facilities are floating liquefaction plants that make it possible to extract, liquefy, and store natural gas at sea, shell and tube heat exchangers for floating liquefied natural gas FLNG. There are multiple crucial steps in the process:

Production platforms or subsea systems are used to produce natural gas from offshore wells.

In order to prevent contaminants from interfering with the liquefaction process, such as carbon dioxide, water, and sulphur compounds, the extracted gas is treated.

The processed gas condenses into liquefied natural gas when it is cooled to extremely low temperatures, usually below -160 degrees Celsius (-256 degrees Fahrenheit) (LNG). The gas must liquefy in order to be transported and stored in smaller volumes.

The produced LNG is loaded into carriers to be transported to markets after being stored in abroad tanks.

The Role of Heat Exchangers in FLNG

Heat exchangers play a crucial role in the FLNG facilities’ liquefaction process. Managing the heat transfer necessary to chill natural gas to the liquefaction stage is their main duty. This entails managing very low temperatures and making sure that heat is exchanged across various process streams effectively. Important considerations for creating heat exchangers for FLNG include:
