Honeywell has announced an agreement with Technip Energies to supply integrated liquefied natural gas (LNG) pretreatment and liquefaction solutions for Commonwealth LNG’s planned export facility in Cameron Parish, Louisiana. The use of Honeywell’s modular technology is expected to help Commonwealth LNG speed up project timelines, simplify execution, reduce construction risks, and improve production efficiency.
The facility will employ Honeywell’s single-mixed refrigerant liquefaction process technology along with six modularized coil wound heat exchangers (CWHEs). This setup is projected to produce 9.5 million tonnes per annum of LNG. According to Honeywell, the CWHEs offer high throughput of natural gas within a compact design, which maximizes processing capabilities while improving safety and operational reliability.
Honeywell UOP SeparSIV pretreatment technology will also be implemented at the site to remove water and heavy hydrocarbons from the gas stream. This technology can handle different feed compositions and may save operators up to half of lifecycle costs compared to traditional removal processes.
John Palamara, vice president and general manager of Honeywell’s LNG business, stated: “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. 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.”
David Lawler, Chief Executive Officer of Caturus, commented: “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. 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.”
Honeywell states that it provides process technology for about two-thirds of global LNG production and integrated pretreatment for around 40% of worldwide capacity. Its modular solutions are designed so they can be built off-site then shipped directly to export facilities—an approach intended to reduce risk and allow faster start-up than conventional construction methods.
