Recycling Helium from Leak Detection Equipment

heliumElementPrism Membrane separators can be used to recover and recycle used helium from leak detection equipment. Helium is often the chosen molecule for detecting leaks in medical devices or industrial fuel lines because it is a small, fast traveling, inert molecule. Due to the world’s limited helium supply, recycling & reusing the valuable gas after leak testing is an economical and attractive effort.

The same reason why helium is chosen for leak detection also makes it a successful gas application for Prism Membrane separators. Fast permeability behavior assists the helium molecules in separating cleanly at high purities in order to be reused again.

We supply membrane separators to helium recycling equipment builders who package systems for end users. Please contact us if you are searching for a membrane supplier for helium recycling.




New Application- Hypoxic Altitude Training

iStock-868638448.jpgPrism Membrane separators generate nitrogen for a wide variety of applications. One process that is gaining interest is high altitude simulation for athletic training. Carefully controlling a slightly elevated nitrogen content in the training chamber simulates the naturally reduced oxygen environment at high altitudes. Hypoxic training provides the benefit of a competitive athletic edge through improved strength training and weight loss.

The purity of nitrogen required to achieve a safe hypoxic environment is well within the capabilities of Prism Membrane separators. At this time, we are actively evaluating relationships with builders of hypoxic gas systems to determine and supply the best fitting membrane solution.


Big Win! Nitrogen Membrane System for Coral FLNG

News Release

Air Products Wins Nitrogen Contract for Coral Floating LNG Project

December 12, 2017 Lehigh Valley, Pa.

Air Products (NYSE: APD) today announced an agreement with TP JGC Coral France for the supply of its Medium and High Purity Nitrogen Package for a floating liquefied natural gas (FLNG) facility to be located in the Indian Ocean, offshore Mozambique, Africa. This represents the company’s second supply contract with TP JGC Coral France for this project. Earlier this year, Air Products announced an agreement to supply its proprietary cryogenic coil wound heat exchanger technology and liquefaction process license for the facility.

The FLNG facility being built by TP JGC Coral France, an incorporated joint venture formed by TechnipFMC and JGC Corporation, along with Samsung Heavy Industries, will utilize Air Products’ advanced PRISM® Membrane Separators to produce both medium- and high-purity nitrogen. The combined nitrogen production will exceed 100,000 Nm3/day. The FLNG plant will be moored and operate on the surface above 6,500 feet of water in the Indian Ocean, in a natural gas field known as Area 4 of the Coral Field.

“Air Products is very pleased to again be selected as a key supplier to the Coral FLNG project,” said Charles Page, director of Air Products PRISM Membranes. “Our Nitrogen Package, which has been designed in accordance with the consortium’s exacting requirements, leverages Air Products’ unparalleled experience for supplying similar equipment for demanding offshore applications.”

“This project affirms Air Products’ capabilities and world class position for supplying high performance membrane nitrogen generation systems for the marine and offshore market,” added Hallgeir Angel, technical sales manager, Air Products AS Engineered Nitrogen Systems. “It builds on years of experience gained on similar complex projects and integrates well in Air Products’ market-leading Nitrogen Package portfolio.”

In support of the LNG industry, Air Products provides process technology and key equipment for natural gas liquefaction processes. Upstream, Air Products provides both nitrogen and natural gas dehydration membrane systems for offshore platforms. Downstream, Air Products provides membrane nitrogen generators for LNG carriers, and land-based membrane and cryogenic nitrogen systems for LNG import terminals and base-load LNG plants.
