Successful Application of Nitrogen Turboexpanders-Compressors to Floating and Land-Based Liquified Natural Gas (LNG) Facilities
MetadataShow full item record
LNG production in the form of large land-based Mega-trains and floating production, storage and offloading facilities (FPSOs) have been of particular interest in recent years. The task of designing and building these facilities and the successful integration of equipment into them can be challenging. Considerations in the scope of the equipment, design features and goals as well as the applications specific needs and end user desires must be considered to end up with a successful design. This paper will explore the differences and similarities in the successful development and application of nitrogen turboexpander-compressors (companders) for both land based and floating LNG (FLNG) applications. The intent is to share general learnings from specific projects and present a roadmap to assist in the successful development and execution of such a product effort. In addition, specific takeaways on the application of machinery to both land-based and shipboard applications will also be presented.
