Greenhouse Gas Reduction

Climate Change due, at least in part, to GHG (GreenHouse Gas) emissions of human-origin has become a major scientific and political issue. In order to deal with it, many countries have ratified the Kyoto Protocol in 2005 and decided to regulate GHG emissions. Transportation and refining activities contribute respectively to 15% and 6.4% of these emissions. To improve the environmental impact of refineries, Axens offers services to refiners to reduce their GHG emissions.

Services

Energy efficiency and Clean Development Mechanisms
The evolution of recent regulations has altered the refining landscape. To adapt to these new rules but also to reduce their costs, refiners will have to implement energy efficiency improvements and projects such as CDM (Clean Development Mechanism) or JI (Joint Implementation). Axens provides a comprehensive Energy Efficiency Improvement offer to achieve GHG emission and production cost reductions.

Biofuels

Meeting future fuel demand is not the sole reason why non-hydrocarbon oil based biofuels are emerging. These fuels will be required to supply a significant share of the motor fuel market in order to reduce pressure on petroleum resources but also to reduce the transportation sector’s carbon footprint and to reduce risks associated with energy security of supply. Axens has developed and continues to work on new processes to produce biofuels.

Esterfip-H™
Axens is present in the first-generation biodiesel market, which involves vegetable oil transesterification. This is a highly efficient, continuous, heterogeneous catalyzed process that produces high-quality diesel and glycerin while generating no waste products. Esterfip-H™ received the Kirkpatrick Award for Chemical Engineering Achievement by the US magazine Chemical Engineering in 2007.

Production of ETBE or TAEE
An alternative approach now viewed as an option for sustainable development is to add ethanol to gasoline. However, direct blending of ethanol in the gasoline pool gives rise to potential problems such as increased RVP, volume reduction, phase separation and logistics. Axens offers performing processes to incorporate ethanol via the etherification routes producing ETBE (Ethyl Tert-Butyl Ether) or TAEE (Tertiary Amyl Ethyl Ether), both very interesting for their excellent octane properties.
Etherification

Gasel™ – a key to clean fuels
The motor fuel sector faces a double challenge: provide an increasing quantity of ever-cleaner fuels and find sources that do not rely on crude oil. Our Gasel™ technology suite answers this challenge through the conversion of synthesis gas (H2+ CO) from various origins (including biomass) into Paraffins that are hydrocracked to produce high quality liquid fuels without impurities.

Other Processes for GHG reduction

Revivoil™
This process, developed jointly with Viscolube Italiana SpA, goes far to put spent oil rerefining on the fast track to success. Unlike traditional spent oil processing, Revivoil™ is successful when it comes to quality, yields, ecology and economics to produce lube bases from spent oils.
