Durasorb™ Cryo-HRU

Innovative, step-change technology with dual-purpose performance: removal of heavy hydrocarbons and water to cryogenic specifications in a single unit.

This new technology provides a simplified pre-treatment line-up and increases feed gas flexibility. Proprietary adsorbents ensure the removal of trace hydrocarbons, including BTX, which can cause freezing in the coldbox and unplanned plant shutdowns. Durasorb Cryo-HRU ensures reliable plant operations and continuous LNG production.

Our Team

On this page


BASF Natural Gas Treatment experts, positioned around the world, work closely with the customer to provide a tailored solution for the most challenging cases, including heavy gas feeds, gas feeds that contain light mercaptans, and light gas feeds that contain trace heavy hydrocarbons and BTX. Our global network of experts respond quickly to customer inquiries and provide unmatched technical support through the lifetime of the unit.


Leveraging decades of experience designing TSA units for the treatment of natural gas, BASF has developed a multi-layer bed that is resistant to liquid hydrocarbon and water carryover and removes trace heavy hydrocarbons, BTX, and water to cryogenic specifications. With an extensive portfolio of adsorbents at their fingertips, technical experts design the bed to address challenging gas feeds and model all aspects of the adsorption unit to ensure continuous operation for more than 4 years. The newly developed product, Durasorb BTX, has 30% greater capacity for benzene, toluene, and xylenes compared to other commercially available materials.

Using proprietary modeling tools, BASF technical experts provide unit simulations, including dynamic adsorption and regeneration profiles. This level of detail allows the customer to fully optimize the plant around the adsorption unit, resulting in CapEx and OpEx savings.
