The Delta LNG export facility is a 20 million tonnes per annum (Mtpa) natural gas liquefaction plant planned to be developed in Plaquemines Parish, Louisiana, US.
The project also includes a feed-gas pipeline from existing gas pipeline intersections near Alto, Louisiana.
Recommended White Papers
Venture Global Delta LNG, a subsidiary of Venture Global LNG, is the developer and operator of the proposed project.
The pre-filing request for the Delta LNG facility and the associated pipeline was accepted by the US Federal Energy Regulatory Commission (FERC) in April 2019. The project is currently under the environmental review process.
The liquefaction facility is planned to be developed in two phases of 10Mtpa capacity each.
The phase one construction works are expected to be started in the second half of 2021 with the start operations expected in 2024.
Location and site details
The Delta LNG facility is proposed to be developed near mile marker 54 of the Mississippi River to the south of New Orleans in Plaquemines Parish, Louisiana, US.
The facility will be built on an approximately 524-acre site on the west bank of the Mississippi River.
Delta LNG export facility make-up
The Delta LNG export facility is proposed to be developed with a total of 18 liquefaction blocks with each block comprising two 0.626Mtpa liquefaction trains.
Each of the 36 LNG trains at the facility will use a single mixed refrigerant (SMR) natural gas liquefaction process.
The export facility will also feature six natural gas pre-treatment units equipped with amine gas-sweetening and molecular sieve dehydration systems, four aboveground full containment LNG storage tanks of 200,000m3 capacity each, and three berths on the Louisiana River for loading LNG carriers of up to 185,000m3 capacity.
The Delta LNG facility will be powered by a 1.24GW gas-fired combined cycle power plant to be built inside the complex.
The facility is expected to process up to 2.8 billion cubic feet per day (bcfd) of gas when operating in full capacity.
Delta LNG development phases
In phase one, nine integrated refrigerant blocks with a total of 18 liquefaction trains and two LNG storage tanks will be developed, while phase two will involve the remaining nine blocks and two more LNG storage tanks.
Delta Express Pipeline
The proposed 48-inch Delta Express natural gas pipeline will run for approximately 485km-long and consist of two natural gas-fired compressor stations at Alto in Richland Parish and Melville in Pointe Coupee Parish.
The pipeline will supply domestic natural gas from the interstate pipeline system’s interconnection point in Alto to the Delta LNG export facility in Plaquemines Parish.
The pipeline will be developed by Venture Global Delta Express, a subsidiary of Venture Global.
The Delta Express Pipeline will pass through 14 parishes in Louisiana to connect the proposed LNG export terminal.
Venture Global’s LNG projects
Apart from Delta LNG, Venture Global is currently developing two LNG projects namely, Calcasieu Pass and Plaquemines with a capacity of 10Mtpa and 20Mtpa respectively. Located also in Louisiana, both the LNG projects received the FERC approval in 2019.
The Calcasieu Pass facility is expected to be commissioned in 2022 while the Plaquemines LNG terminal is scheduled for commissioning in 2023.
