Safely and reliably supplying power to Ebara’s cryogenic pumps
Fueled by rising demand from energy-hungry economies such as China, India, and other Asian countries, the demand for shipping and storing Liquefied Natural Gas (LNG) is expanding much faster than projects can come onstream. Gas companies are spending billions of dollars building LNG plants.
One fundamental contributor to the effectiveness of such huge investments is extremely reliable, high-performance equipment.
Since 1974, Ebara International Corp.’s Cryodynamics Division has been supplying more than 6000 pumps and expanders for LNG carriers and landbased facilities. Its pumps and expanders are designed to operate completely immersed in cryogenic liquids. This calls for a commitment to safety and quality that embraces all related components. Since the late 1990s, Ebara has therefore increasingly been equipping its installations with glass-to-metal sealed electrical terminal headers made by SCHOTT Electronic Packaging. They serve as the hermetic feedthroughs for the three-phase electrical power.
In the April 2013 issue of „LNG Industry“, Thomas Goettlinger, SCHOTT in Germany, and Don Polkinghorn, Ebara, USA, explain the technology needed to steadily and securely feed LNG pumps with power.
