“As part of initial commissioning of midscale liquefaction Train 4, Cheniere and EPC contractor Bechtel will begin startup/commissioning operations,” according to a report filed by Corpus Christi Liquefaction with the Texas Commission on Environmental Quality.
“Cheniere will be utilizing good engineering practices during the startup/commissioning activities. The thermal oxidizer, furnace, and ground flares will be maintained and operated during startup/commissioning activities to ensure hydrocarbons are properly combusted, ” the company said.
Separately, CCL also received approval from the US FERC on Wednesday to introduce propane into the midscale Train 4 thermal oxidizer and hot oil furnace for the Stage 3 project.
Seven trains
Cheniere’s Corpus Christi plant currently liquefies natural gas at three operational trains, each with a capacity of about 5 mtpa.
In June 2022, Cheniere made the final investment decision on the Corpus Christi Stage 3 expansion project, worth about $8 billion, while compatriot Bechtel officially started construction on the project in October of the same year.
The project includes building seven midscale trains, each with an expected liquefaction capacity of about 1.49 mtpa.
In March 2025, Cheniere achieved substantial completion of the first liquefaction train at the Corpus Christi Stage 3 expansion project, while the company completed the second liquefaction train in August.
Cheniere is also nearing the completion of the third train.
Last week, FERC granted CCL’s request to introduce feed gas and refrigerants to the cold end of the midscale Train 3 – string 1, and hydrocarbons to the train 3 condensate system.
Cheniere said in its second-quarter results that it still expects substantial completion of Train 3 and first LNG from Train 4 before the year-end of 2025.
The Stage 3 expansion project was 87.9 percent complete as of the end of July.
