LNG export facility will use online gas chromatographs to monitor product quality
ABB to provide process analyzers for Cheniere Energy’s new Sabine Pass LNG export facility on the gulf coast.
Cheniere Energy has selected ABB to supply process analyzers, system integration, and related services for its new Sabine Pass LNG (liquefied natural gas) export facility in Cameron Parish, La. The new export facility is currently being built by EPC contractor Bechtel as an expansion of Cheniere’s existing Sabine Pass natural gas storage and import terminal. When completed, it will be able to accommodate up to four LNG trains capable of processing approximately 2 Bcf/d (billion cubic feet of natural gas per day) to liquefy the gas for transport and potential export. The initial project under construction includes two trains with a liquefaction capacity of 1 Bcf/d.
The analyzers will help measure and control LNG quality at all points in the process by providing precise, continuous online measurements of critical variables as the gas is turned into liquid. The scope of supply encompasses a range of online process analyzer systems, including ABB’s PGC 5000, PGC 1000 process gas chromatographs, and AO 2000 continuous gas analyzers for both LNG trains and environmental enclosures to protect the devices. The gas sample systems will extract product from different parts of the process and then return it so no product is lost during analysis. The analyzers will measure the ppm level of various chemical components, as well as physical properties of the gas such as pH, conductivity, and density to ensure optimal product quality and process stability. ABB will integrate the analyzer systems with other site systems, and will also provide project management and system design services, system fabrication and testing, and related documentation.
