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.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
