Evonik has delivered SEPURAN membranes to over 1,000 reference plants

Since the product launch in 2011, Evonik has delivered gas separation membranes in more than 1,000 reference plants worldwide as of the end of 2021. Within just one decade, the specialty chemicals company has become a globally recognized technology leader in polymer-based SEPURAN membranes for efficient gas separation. The Group is experiencing continued strong demand in biogas, nitrogen (N2), hydrogen (H2) and natural gas applications. The expansion of existing production capacities at the Austrian site in Schörfling am Attersee is progressing. 

"Having developed and established the biogas industry in close cooperation with our partners, we are establishing now our SEPURAN membranes in demanding nitrogen, hydrogen and natural gas applications," says Dr. Iordanis Savvopoulos, Head of the Fibers, Foams and Membranes Product Line at Evonik. "We celebrated the 500th biogas reference plant just under a year ago, and now the next market success for the entire membrane portfolio is hitting us, giving us an important boost for further growth. The market is convinced of our innovative membrane technology." 

At the heart of Evonik's SEPURAN membrane technology are polymer-based hollow-fiber membranes made of the high-performance polymer polyimide developed in-house. Evonik is the world's only backward-integrated manufacturer of highly selective gas separation membranes. 

"Backward integration is the key driver of our innovative strength," emphasizes Dr. Goetz Baumgarten, head of the Membranes Innovation Growth Field at Evonik. "Thanks to our many years of expertise in polymer chemistry, we already adjust the membrane properties at the development stage of the base material—our high-performance polymer—in order to produce particularly selective, productive, and robust membranes that can be used even under extreme process conditions-such as those found in the oil and gas industry or in aviation."

Polymer-based membrane technology for gas separation 

SEPURAN membranes make it possible to separate gases such as methane (CH4), N2, or H2 from gas mixtures. The advantages of Evonik's membrane technology are more precise separation of the gases and higher productivity. SEPURAN N2 membranes for efficient nitrogen generation are used, for example, to inert aircraft tanks. SEPURAN Noble membranes extract hydrogen transported through natural gas pipelines selectively from the CH4/H2 gas mixture at the delivery points. SEPURAN NG membranes enable efficient natural gas processing from gas sources with high CO2 concentration. 

Evonik launched its first membrane product—SEPURAN Green, for efficient upgrading of biogas—on the market in 2011, laying the foundations for future business in membranes. This was followed by further membrane products for N2, helium, H2, natural gas, and nanofiltration applications. The membranes, which are now being successfully used in more than 1,000 system installations worldwide, are produced at Evonik’s site in Schörfling, Austria. The high-performance polymer-based material is produced in neighboring Lenzing.

FEATURED COLUMNS

Editorial Comment
-Lee Nichols
The gas processing/LNG sector is investing in new technologies to mitigate carbon emissions from both operations and its supply chain.
Industry Focus: Maximizing the performance of your ETRM system
-Teresa Kroh, Brad York
Energy trading and risk management (ETRM) systems are vital for the support of business processes associated with trading energy commodities such as crude oil, refined products, natural gas, natural gas liquids (NGLs) and electric power, as well as facilitating the movement and delivery of those energy commodities and associated risk management activities.
Sustainability
-Oz Rodriguez, Catriona Penman
More than 100 participating countries at the 26th UN Climate Change Conference of the Parties (COP26) signed the Global Methane Pledge, in which they agreed to take action to reduce methane emissions at least 30% by 2030 vs. 2020 levels.


Optimizing Gas Distribution: Accounting for Changeovers, Regulators, and More

Gas distribution systems are critical to the effective operation of many industrial facilities around the world. Despite the importance of these systems, however, opportunities to improve their performance and cost-effectiveness are often missed or misunderstood. Increasing changeover pressure may seem like a good way to improve system flow, for example, but it often does so at the expense of bottled gas. Adding regulators may help you control supply pressure, but it also adds cost to your system. So, how do you know what the ideal gas distribution setup is for you?

Attend this webinar to:

  • Gain a basic understanding of the fluid dynamics that affect pressure control in gas distribution systems, learning to interpret flow curves and recognize phenomena like lockup, droop, and supply pressure effect (SPE)
  • Learn how inlet pressure affects regulator performance and when to specify certain regulator types and configurations to effectively control gas system pressures

Understand the inherent trade-offs between gas utilization and flow capacity and how to select both the right changeover pressure and automatic changeover panel design for your operations.
