Power and automation technology group ABB has been chosen to supply process analyzers, system integration and related services for Cheniere Energy’s Sabine Pass liquefied natural gas (LNG) export facility in Cameron Parish, La.

Located four miles from the Gulf Coast in southwest Louisiana, 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 billion cubic feet of natural gas per day (Bcf/d) 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.

ABB’s delivery for the project will help to measure and control the quality of the LNG at all points in the process, by providing precise, continuous online measurements of critical variables as the gas is turned into liquid, according to a company statement.

“We are very pleased to be involved in this important energy project,” said Charles Young, head of ABB’s Measurement Products business in the U.S.  “Reliable and accurate information will help the customer maintain consistently high product quality while optimizing efficiency and cost during the production process.”

The scope of supply includes Online Process Analyzer Systems comprised of 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 (parts per million) 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.

The project is scheduled to be commissioned in 2015.
