Air Liquide will supply the BW Magna floating storage and regasification unit (FSRU) with two Turbo-Brayton cryogenic units.

A first for the industrial gas giant, the cryogenic units will help store the natural gas in liquid for in the best possible conditions.

Once complete, BW Magna will store and regasify natural gas that is transported by sea from production regions of the world.

Shipping company BW LNG has signed a 23-year contract to store and regasify natural gas at sea before transferring it to the electricity generation plant operated by Gas Natural Açu.

For this project, Air Liquide supplies a Boil Off Gas reliquefaction solution in order to maintain the cargo at cryogenic temperature based on the principle of subcooling. 

Air Liquide’s Turbo-Brayton cryogenic units sub-cool the liquid natural gas and send it back directly in the tanks, preventing it from evaporating and increasing the pressure.

In cases when the energy dispatch of the Açu thermoelectric plant is not required, the Turbo-Brayton will prevent the cargo losses on the FSRU.

The commercial operation of the first plant of the complex is to start in the second quarter of 2021.
