Natural Gas Treatment

BASF Natural Gas experts have a diverse portfolio of products to custom design a solution and help you meet your Natural Gas treatment needs.

BASF has been serving the natural gas treatment market for over 60 years. The Sorbead portfolio is used for the simultaneous removal of water and heavy hydrocarbons for pipeline transportation and underground storage of natural gas. BASF has extended this knowledge and expertise to serve the LNG pre-treatment market with its Durasorb® portfolio.

Why BASF?

Durasorb® is BASF’s innovation platform for the LNG industry and a custom-tailored solution that combines superior adsorbents with BASF’s expert designs.

Natural gas experts use proprietary design software to model the performance of the adsorbents in all parts of the vessel and optimize the temperature swing adsorption process. Based on the design calculations, BASF natural gas experts choose the ideal combination of adsorbents from the comprehensive BASF portfolio. The resulting installation ensures more efficient removal of contaminants, increases feed gas flexibility, and extends unit lifetime.

Portfolio of Products

BASF provides the full LNG pre-treatment package with its Durasorb® and OASE Gas Treatment technology.

Innovative products and technologies solve problems at the plant by removing impurities and providing reflux resistance to increase unit lifetime. Depending on the gas feed conditions, the HRU and Dehy unit can be combined into a single unit, Durasorb® LNG MAX, capable of removing heavy hydrocarbons and water to cryogenic specifications.

Durasorb® LNG MAX
Our innovative technology with dual-purpose performance: removal of heavy hydrocarbons, including BTX, and water to cryogenic specifications in a single unit.

ExxonMobil awards BASF Durasorb™ Cryo-HRU with technology qualification for LNG pre-treatment

BASF received the ExxonMobil technology qualification for its Durasorb™ Cryo-HRU technology following extensive discussions and technical evaluation. Durasorb Cryo-HRU is an LNG pre-treatment technology that removes both heavy hydrocarbons (HHCs, including C8+ and BTEX) and water from natural gas prior to entering the liquefaction section of the plant.  Removal of HHCs and water in a single unit saves capital expenditure and operational costs and prevents freezing in the cold section of the plant. Cryo-HRU is suitable for new units and retrofits. By increasing efficiencies in the production process, Durasorb Cryo-HRU helps to decrease energy consumption and the CO2 footprint of LNG production.

Shell qualifies BASF Durasorb™ Cryo-HRU technology for removal of heavy hydrocarbons and water from natural gas

Leveraging the extensive know-how and experience of BASF adsorption experts, Shell has qualified BASF Durasorb™ Cryo-HRU technology for deployment in Shell gas processing plants with lean feed gas streams. Use of Durasorb Cryo-HRU technology, in the pre-treatment section of an LNG production plant offers an effective solution for the removal of trace HHCs, BTEX (benzene, toluene, ethylbenzene, xylene), and water to cryogenic specifications in a single unit. HHCs and BTEX impurities are known to cause freezing in the coldbox resulting in plant downtime and are especially challenging due to the need to remove deeply even from lean feed gas streams. Durasorb Cryo-HRU effectively removes these impurities while also removing water to cryogenic specifications. Implementing Durasorb Cryo-HRU in the LNG pre-treatment section ensures reliable operation and provides operational flexibility to the plant.
