Atlantic LNG Train 4: the world's largest LNG train.

Author(s) : DIOCEE T. S., HUNTER P., EATON A., et al.


The Atlantic LNG facility located in Point Fortin, Trinidad, is comprised of three LNG trains using the Phillips Optimized Cascade LNG Process and each producing approximately 3.3 MTPA of LNG. A fourth LNG train, designed for a nominal production capacity of approximately 5.2 MTPA, is the world's largest LNG Train currently under construction. Atlantic LNG Train 4 is scheduled to be started up in the 4th quarter of 2005. In this paper the authors present the design premise for the fourth LNG train and discuss how the "Two-trains-in-one" concept was maintained while increasing the capacity. The changes to plant layout, equipment, and piping and instrumentation are addressed, as are the dynamics of the plant. The selection processes for major equipment are also discussed. General areas of concern were addressed during the conceptual phase of the project, and the authors discuss how these concerns were overcome. The paper also discusses some of the decisions made concerning the use of multiple pieces of equipment versus a smaller number of larger pieces of equipment.
