Italian industrial gas specialist SIAD Macchine Impianti (SIAD MI) will supply four air separation units (ASUs) for the North Field East (NFE) liquefied natural gas (LNG) development project in Ras Laffan Industrial City, Qatar.

Selected for its ability to produce tailor-made plants, the company will provide GNT 4750-type plants, designed to generate high purity nitrogen through cryogenic air separation. 

Delivery of the plants will be accompanied by two auxiliary storage and vaporisation systems.

Claimed to be the largest LNG development project in the world, NFE is expected to increase the LNG production capacity of Qatar from 77m tonnes per annum (Mtpa) to 110Mtpa by 2025. 

The second phase of the North Field expansion – known as the North Field South project – is expected to increase Qatar’s LNG production capacity from 110Mtpa to 126Mtpa by 2027.

Project operator Qatargas is currently handling 14 LNG trains at Ras Laffan. 

SIAD MI expects delivery of the ASUs and auxiliary systems to be completed by September 2023
