New heat exchanger technology for air-cooled LNG facilities

Together with Wieland Thermal Solutions and Technip, this company has developed a new technology to boost efficiency for air-cooled liquefied natural gas (LNG) facilities, known as Diesta (short for dual internally and externally structured tube for air-coolers). Diesta (photo) is a combination of two established technologies for the outside and inside of a tube, the key component of an air-cooler. Diesta technology typically allows increase in LNG production by 2 to 3%, while taking advantage of compression power savings. Moreover, the equipment footprint can be reduced by up to 20% due to a more compact design. Finally, the reduction in specific fuel-gas consumption lowers CO2 emissions, says the company. — GEA Batignolles Technologies Thermiques SAS, Nantes, France
