Chart receives BAHX orders

Chart Energy & Chemicals Inc., a subsidiary of Chart Industries Inc., has been awarded a contract by Babcock to provide brazed aluminium plate fin heat exchangers (BAHX) for its patent-pending ecoSMRT® LNG reliquefaction system that recovers excess boil-off gas (BOG) on-board LNG vessels.

BOG recovery is fundamental to increasing cost efficiencies and environmental credentials of today’s LNG ship fleets and ecoSMRT is a highly versatile solution that can be installed on new vessels as well as retrofitted onto older ships, and deployed on both large and small carriers as well as bunkering vessels.

BAHX characteristics are fundamental to ecoSMRT’s key features. The multi-stream capability enables an ecoSMRT plant to incorporate single mixed refrigerant (SMR) cooling within the BAHX, which removes the need for a separate refrigeration plant. The turndown capability of BAHX enables ecoSMRT to operate at 30% to 100% reliquefaction capacity to match the BOG system requirements. Engineers at both Babcock and Chart have also worked extensively on the overall design to ensure that the system is as compact and lightweight as possible.

George Arnett, Chart Energy & Chemicals Inc. Vice President Global Energy Sales & Marketing, said: “Chart prides itself on being at the vanguard of LNG technology and we are delighted with this latest award and the opportunity to team up with Babcock LGE and assist in introducing a highly innovative solution into the marketplace.”

Neale Campbell, Babcock LGE Managing Director, added: "Babcock’s recent ecoSMRT contract to Chart highlights our ongoing collaboration within the LNG market. Similarly, Babcock is developing an increasing footprint across the LPG, ethane and ethylene carrier markets through our supplementary technologies.”

Babcock’s selection of Chart BAHX solidifies its approach to deliver proven, reliable technology. There are more than 500 Chart BAHX in LNG service around the globe, from small peak-shaving plants right through to large baseload facilities, including some built in the 1970s that are still operating today. As well as land based plants, Chart has also supplied BAHX offshore and it was a Chart unit that earned the distinction of being the first to produce LNG on-board a floating vessel.
