Plaquemines LNG 20 MTPA Export Facility

Plaquemines LNG 20 MTPA Export Facility

Venture Global has set out to disrupt the LNG industry paradigm by taking a bottom-up approach to capital cost. Our customers will benefit from our savings with a low-cost, reliable supply of LNG.

Overview

Plaquemines LNG key project features include a liquefaction plant consisting of 18 liquefaction blocks developed in two phases, with each block having a nameplate capacity of 1.2 million metric tonnes per annum (MTPA) and consisting of two SMR liquefaction units and ancillary support facilities. It will also contain four 200,000-cubic-meter LNG above-ground storage tanks with cryogenic pipeline connections to the liquefaction plant and berthing docks.

Additionally, the facility will include up to three marine loading berths for ocean-going ships capable of receiving LNG carriers up to 185,000 cubic meters in capacity. It will also include a utility dock on the Mississippi River to handle waterborne deliveries of equipment and material during both construction and project operations.

Plaquemines LNG will use a combined-cycle gas-turbine (CCGT) power plant with a generating capacity of approximately 611 megawatts (MW) plus an additional 25 MW gas-fired turbine for phase one. The power plant will be expanded in phase two to include an additional 611 MW of generating capacity plus an additional 25 MW gas-fired turbine.

Modular Design

The modular design enables a broad range of equipment suppliers, including compressors, valve piping commodities, etc. This design also means:

  • Our LNG liquefaction “blocks” consist of two cold boxes with a integral heavy hydrocarbon removal sections.
  • Three integrated pre-treatment units consisting of 50 percent plant capacity each will feed the nine “blocks.”
  • Our technology choice is an industry standard single mixed refrigerant (SMR) process that has proven high reliability metrics.
  • LNG facilities using the modular concept of .626 MTPA can build plant capacity in incremental steps if desired.
  • Electric motors sized for .626 MTPA are easier to start than larger motors.
  • The modular design enables quicker assembly in the field and is key to our cost reductions.

Combined-Cycle Gas-Turbine Power Plant

Per phase, each 611 MW inside-the-fence CCGT power plant will use feed-gas, together with boil off gas, to produce the power required to drive the electric motors of the liquefiers. Our “5 on 2” gas turbine to steam turbine configuration allows for significant flexibility for maintenance or down times, allowing the facility to have extremely high availability for production. There will also be one aeroderivate gas turbine per phase for startup and peaking needs.

Lateral Pipelines

The project will be interconnected via two lateral pipelines reaching to existing interstate and intrastate pipelines.
