Air Products AS in Kristiansand, Norway recently received its single largest order of PRISM® nitrogen systems for shipboard applications in the last 30 years.
The order, from one of the world’s largest energy companies, involves retrofitting 25 liquefied natural gas (LNG) vessels by replacing a competitive nitrogen system with a new one that incorporates Air Products’ proprietary PRISM® membrane technology.
“This order is evidence of the high performance and reliability of Air Products’ PRISM nitrogen systems for onsite gas generation,” said Rune Damsgaard, business director of Air Products Norway. “The continuous supply of nitrogen that these systems provide onboard LNG carriers is of vital importance in securing the vessels’ safety, both at sea and during loading and offloading of fuels.”
Each of the shipboard nitrogen systems is engineered with Air Products’ PRISM® membrane separators , manufactured exclusively at Air Products’ facility in St. Louis, Mo. PRISM membrane separators contain polymeric hollow fibers that use selective permeation under differential pressure to separate nitrogen from oxygen and other elements.
Air Products AS specialises in the engineering and fabrication of shipboard nitrogen systems, which produce nitrogen onsite primarily for inerting potentially hazardous fueling operations. To date, the company has delivered more than 1,000 PRISM nitrogen systems for a wide variety of ship applications and more than 220 systems for offshore installations.
