Babcock markets new ethane boil off gas technology

Published by , Editorial Assistant

Utilising Babcock’s existing technologies of SuperCooler and VentGasCooler (VGC), ecoETHN integrates the reliquefaction system with the fuel gas supply system, enabling reliquefaction of methane-rich boil off gas (BOG) that can be used as fuel for main engine and auxiliary power generators. This product achieves reductions in greenhouse gas emissions and promotes safe and efficient vessel operations – providing environmental and commercial advantages.

ecoETHN is designed to handle ethane cargoes with high methane content and also effectively handles methane enrichment in the BOG more efficiently than conventional reliquefaction solutions. It is a cost effective solution that minimises both capital and operational expenditure through the unique combination of reliquefaction and a fuel delivery system.

Neale Campbell, Managing Director, Babcock LGE said: “ecoETHN is a breakthrough addition to our portfolio of gas handling technologies. We continue to challenge ourselves and develop solutions that we believe will meet the current and future needs of our customers while providing environmental and commercial benefits within the gas handling market.

“A key advantage of ecoETHN is that it allows methane content up to 2.0 mol% in the liquid phase to be transported for the next generation of VLEC/ULEC for typical ethane cargoes out of the USA.

“Innovation is at the heart of our business and ecoETHN is already attracting significant interest from a number of global ship owners and shipyards. We are excited by the unique benefits that this technology will deliver for all stakeholders across the ethane value chain.”
