Did you know there can be 5x more air pollution inside your house than outside of it? Indoor Air Quality (IAQ) refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. Understanding and controlling common pollutants indoors can help reduce risk of indoor health concerns. BASF offers the widest portfolio of adsorbent technologies for a broad spectrum of applications in industries such as refining, petrochemical, chemical, and gas processing. The BASF portfolio includes proprietary alumina, silica, alumino-silica gels and a broad line of base metal oxide guard bed materials, including the PuriStar family. At BASF, our Fluid Catalytic Cracking (FCC) catalyst and additive offerings together with our expert technical services build the right solution to create value within any unit’s constraints. The increasing demand for energy and resources is what drives us to develop more sustainable solutions, while addressing the need for energy efficiency and conservation.

Novel process developed to recover high value products from natural gas

  • New process successfully combines treatment of natural gas for pipeline transportation with the simultaneous recovery of valuable helium, liquid hydrocarbons, and purified CO2
  • Customers benefit from purified natural gas for pipeline transportation and additional value streams from their process
  • Access to a new highly profitable helium source, employing a non-cryogenic process
  • Joint presentation by Linde and BASF during Gastech conference from September 17-19 in Houston

Ludwigshafen, Germany and Pullach, Germany, September 9, 2019 – Linde developed a novel process to recover high value products from natural gas successfully combining leading technologies of BASF and Linde.

The process simultaneously recovers valuable helium, liquid hydrocarbons, and purified CO2 in addition to conditioning natural gas for pipeline transportation adjusting the water and heavy hydrocarbon dew point, as well as the CO2 concentration.

Helium is commonly recovered from natural gas when a cryogenic separation is employed. The hybrid process eliminates the need for cryogenic conditions, giving access to a new highly profitable helium source.

The process consists of two stages of Linde’s HISELECT® Powered by Evonik membranes, an upstream BASF Durasorb™ hydrocarbon removal unit (HRU), an integrated BASF OASE® acid gas removal unit (AGRU) and an integrated Linde Helium PSA unit. The two HISELECT® membrane stages are simultaneously used for helium enrichment and adjustment of CO2 to pipeline specification. The Linde Helium PSA purifies the enriched helium up to 99.999% with highest yield. BASF’s OASE® AGRU is used to selectively remove the CO2 from an internal recycle without any helium or methane loss. BASF’s DurasorbTM HRU removes heavy hydrocarbons and water to meet pipeline dew point, produce liquid hydrocarbons as valuable byproduct and to ensure high membrane performance.

The combination of these technologies and the expertise of the companies allows for optimization of performance and the generation of additional value streams from the gas treating process. A project utilizing this approach will generate additional revenue, resulting in a high ROI and short payback period.

”The newly developed process changes project economics and helps our customers to generate additional value. As an additional high value stream can be generated, we’ll see more projects move forward,” says Detlef Ruff, Senior Vice President Process Catalysts at BASF.

“It is exciting to see how the combination of technology from three leading companies result in such a unique, efficient and sustainable process,“ says Tobias Keller, Head of Linde Engineering’s Adsorption and Membrane Plants.
