T2.7 Debottlenecking of LNG plants

Global energy demand is increasing, and gas is likely to make up a significant part of the world’s energy supply for decades to come.

This paper provides an analysis of debottlenecking solutions applied at LNG plants. Shell Projects and Technology (P&T) is responsible for the planning, designing, engineering and constructing oil and gas projects and has extensive experience with LNG plants.

Debottlenecking projects, range from end flash gas debottlenecking, coil-wound heat exchangers replacement, refrigerant compressor re-wheeling, etcetera and which typically demonstrate low cost production increases. These brownfield projects often encounter very challenging circumstances to be able to execute these projects effectively at low costs. Plant turn-around schedule, actual equipment performance and concurrent projects on site can make debottlenecking choices challenging.

A disciplined approach for debottlenecking helps to select through a range of options efficiently to find the most suitable solution.  In a recent project Shell P&T worked closely with the asset team in Oman LNG and a rotating equipment supplier to take into consideration these challenges. A practical methodology for debottlenecking was applied using a competitive scoping staircase, operational and engineering experience together with simulation tools. The selected debottlenecking was de-risked and matured to preserve the project key value drivers.
