Honeywell has partnered with Technip Energies to provide integrated pretreatment and liquefaction solutions for the Commonwealth LNG export facility in Cameron Parish, Louisiana. Utilizing Honeywell’s modular technology, the project aims to accelerate construction timelines, reduce execution risks, and maximize production efficiency to address growing global energy needs.

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.

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.

"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.”
