Honeywell and Technip Energies Partner to Accelerate Commonwealth LNG Project
Honeywell and Technip Energies have formed a strategic partnership to accelerate the Commonwealth LNG export project in Louisiana, deploying advanced modular pretreatment and liquefaction technologies. The collaboration aims to shorten construction timelines, reduce risk, and deliver a high-efficiency 9.5 MTPA LNG facility to meet rising global energy demand.

Honeywell recently announced a strategic agreement with Technip Energies, a leading engineering, procurement and construction (EPC) contractor, to provide integrated liquefied natural gas (LNG) pretreatment and liquefaction solutions. This technology is destined for Commonwealth LNG's planned export facility in Cameron Parish, Louisiana. Honeywell's modular technology will enable Commonwealth LNG to expedite project timelines, simplify execution, mitigate construction risks, and enhance production efficiency to meet increasing energy demand.
Modular Liquefaction: Scaling 9.5 Million Tonnes Per Annum
Commonwealth LNG, part of the Caturus platform, will use Honeywell's single‑mixed refrigerant liquefaction process technology and six modularized coil wound heat exchangers (CWHEs) to produce a projected 9.5 million tonnes per annum of LNG. Honeywell's CWHEs provide the highest throughput of natural gas within a compact footprint, maximizing processing capabilities with a space-saving design, while enhancing safety and operational reliability.
Cost-Efficient Pretreatment with Honeywell UOP SeparSIV
Additionally, Honeywell UOP SeparSIV® pretreatment technology will be used to remove water and heavy hydrocarbons to meet the required LNG specifications. The technology can be used with varying feed compositions and can save operators up to 50% of lifecycle cost versus traditional removal processes. This flexibility is vital for North American export facilities receiving gas from diverse upstream sources.
Strategic Global Energy Security and ROI
"Honeywell's end-to-end LNG solutions and modular delivery model options can help customers reduce construction timelines, increase speed to market and ultimately enhance the return on their investment," said John Palamara, vice president and general manager of Honeywell's LNG business. "The combination of our innovative technologies with our deep industry expertise can help to optimize every phase of the LNG process, supporting global energy security needs." "This significant capital investment in the Commonwealth LNG platform is a key milestone, along with the financing process, which is well underway, and illustrates our level of commitment to developing this global-scale LNG project," said Caturus Chief Executive Officer David Lawler. "The Commonwealth project is a crucial component of Caturus' wellhead-to-water strategy, and this is another important step toward building the nation's leading independent integrated natural gas company."
Leading the Global Shift to Modular LNG Infrastructure
Honeywell is a global leader in LNG process technology and automation, including pretreatment and liquefaction technologies along with cutting-edge automation and software technologies to help optimize the overall LNG process scheme. The company is responsible for liquefying about two-thirds of the world's LNG and provides integrated pretreatment for about 40% of global LNG capacity. Honeywell provides customers with various options for modular LNG technology solutions that can be built off-site and shipped to export facilities, helping reduce risk and expedite construction timelines to enable LNG facilities to enter operation quicker than those built with traditional construction methods.
