Honeywell and Argent LNG have entered into an agreement that could reshape the future of liquefied natural gas exports from the United States. Central to the partnership is a plan to develop a large-scale LNG export terminal in Port Fourchon, Louisiana. The facility is expected to produce up to 12 million tons per year of LNG, with the potential to expand to 25 million tons annually. This would position it among the most substantial LNG export terminals in the world.

Port Fourchon, located along the Gulf Coast, plays a crucial role in the country’s energy infrastructure. Argent LNG’s decision to build in this location reflects its logistical strengths and the growing global demand for US LNG. With Honeywell’s advanced pretreatment technologies, the project aims to optimize output while meeting rigorous safety and quality standards.

How Honeywell’s pretreatment technologies improve gas readiness

Honeywell’s contributions to the Port Fourchon facility include three key technologies: the Mercury Removal Unit (MRU), the Acid Gas Removal Unit (AGRU), and the SeparSIV Unit. Each serves a specific purpose in the LNG preparation process.

The MRU addresses mercury removal, which is essential to prevent corrosion of aluminum cryogenic exchangers. The AGRU eliminates acid gases like carbon dioxide and hydrogen sulfide. The SeparSIV Unit provides the final stage of dehydration and removal of heavy hydrocarbons, ensuring the gas is suitable for liquefaction.

The SeparSIV Unit stands out due to its adaptability to varying feed compositions. It is a modular solution that can reduce lifecycle costs by up to 50 percent compared to traditional pretreatment methods. For Argent LNG, this approach supports both cost control and project scalability.

Port Fourchon’s rising profile in the global LNG landscape

Traditionally known as a support base for offshore oil and gas operations, Port Fourchon is evolving into a major LNG hub. Its access to Gulf shipping routes, coupled with a supportive regulatory framework, makes it an ideal site for high-capacity LNG infrastructure.

The Argent LNG project strengthens the port’s importance in the global LNG supply chain. As countries seek to reduce dependence on coal and diversify their energy sources, well-located and efficient LNG export terminals are becoming increasingly valuable. Honeywell’s involvement signals strong technical and operational backing for the facility.

Meeting global LNG demand with flexible and cost-effective systems

Global demand for LNG is projected to increase by 60 percent by 2040, according to the Shell LNG Outlook. This growth will largely come from regions prioritizing energy security and emissions reductions, including parts of Asia and Europe.

To respond to this shift, LNG producers are under pressure to develop facilities quickly and cost-effectively. Honeywell’s modular pretreatment systems are designed for rapid deployment and operational flexibility.

Cleaner and more efficient LNG production is central to energy transition strategies worldwide. Honeywell’s technologies support this direction by improving gas quality and reducing the environmental footprint of export terminals.
