T3.8 Improved LNG line-up

A recent industry development is the use of pipeline gas, rather than natural gas, as the feed source for LNG projects. Despite the limited amount of heavier hydrocarbon components in this feed, pipeline gas projects have continued to require a natural gas liquids (NGL) extraction unit in the line-up because it performs another critical function: deep benzene, toluene, ethylbenzene and xylene (BTEX) removal.

However, a flagship project about to enter the detailed engineering phase has adopted a line-up in which an acid gas removal unit (AGRU) using Shell’s Sulfinol technology undertakes BTEX removal, resulting in major CAPEX reductions. A new gas processing line-up is helping to cut the capital cost of LNG Canada’s proposed LNG export facility in Kitimat, Canada. For a typical design, this is estimated to be upwards of US$100 million. This talk details the proposed new line-up and the advantages that it provides, describes the type of opportunities for which it is best suited and explains the R&D work that has provided LNG Canada with the confidence to build a world-first facility on this basis.
