FERC approves Texas LNG project and supplying pipeline

The Federal Energy Regulatory Commission on Dec. 30 approved an August 2012 application from Corpus Christi Liquefaction LLC for approval to site, construct, and operate liquefied natural gas (LNG) export and import facilities on the northern shore of Corpus Christi Bay in San Patricio and Nueces counties, Texas.

Also in August 2012, Cheniere Corpus Christi Pipeline LP filed an application for a certificate of public convenience and necessity to construct and operate a 23-mile-long, 48-inch-diameter pipeline in San Patricio County to transport natural gas bi-directionally between the Liquefaction Project and existing interstate and intrastate natural gas pipeline systems.

“We conclude that, with the conditions required herein, Corpus Christi Liquefaction’s project results in minimal environmental impacts and can be constructed and operated safely,” said the Dec. 30 approval. “Accordingly, we find that, subject to the conditions imposed in this order, Corpus Christi Liquefaction’s proposal is not inconsistent with the public interest. We will also authorize Cheniere Pipeline’s proposal under section 7(c) of the [Natural Gas Act] to construct and operate the Pipeline Project.”

Corpus Christi Liquefaction is a subsidiary of Corpus Christi LNG LLC, which is a subsidiary of Cheniere LNG Inc., which is a subsidiary of Cheniere Energy Inc. Cheniere Pipeline is a subsidiary of Cheniere Pipeline Co., which is a subsidiary of Cheniere Energy Inc.

The proposed Liquefaction Project would have the capability to liquefy for export approximately 15 million metric tons per annum (MMTPA) of LNG and vaporize approximately 400 million cubic feet (MMcf) per day of imported natural gas. Corpus Christi Liquefaction states that Cheniere Marketing LLC would export and import the LNG by LNG carriers, totaling between 200 and 300 trips per year through Corpus Christi Bay.

Specifically, Corpus Christi Liquefaction proposes to construct three liquefaction trains, each with a liquefaction capacity of approximately 5 MMTPA. Pending export, the LNG will be stored in three proposed 160,000 cubic meter (m3) full containment LNG storage tanks, each equipped with five in-tank well columns and safety and monitoring systems. The Liquefaction Project will also include two trains of ambient air vaporizers, each with an average vaporization capacity of approximately 200 MMcf per day of natural gas.

Each liquefaction train will contain:

  • facilities to remove carbon dioxide, hydrogen sulfide, and sulfur compounds from the feed gas;
  • facilities to remove water and mercury from the feed gas;
  • facilities to remove heavy hydrocarbons (e.g., benzene, toluene, ethylbenzene, and xylene) from the feed gas;
  • six gas turbine-driven refrigerant compressors;
  • waste heat recovery systems for regenerating the gas driers and amine system; and
  • induced draft air coolers.

Cheniere Pipeline will transport domestic natural gas to Corpus Christi Liquefaction’s proposed LNG terminal for liquefaction and export, as well as to transport regasified imported LNG from the LNG terminal to interconnections with the existing pipeline systems of Texas Eastern Transmission, Kinder Morgan Tejas Pipeline LLC, Natural Gas Pipeline Co. of America, Transcontinental Gas Pipe Line, and Tennessee Gas Pipeline. The proposed pipeline will have a peak capacity of 2.25 Billion cubic feet (Bcf) per day.
