Making the shift from fossil to renewable fuels comes with tough challenges – and materials expertise plays a key role in overcoming them. For years, we’ve helped our customers select the right alloys and steels to help reduce operational costs and ensure reliable, long-term performance in demanding environments.
If you’re designing or operating biorefineries, Sustainable Aviation Fuel (SAF) plants, Hydrotreated Vegetable Oil (HVO) plants, or biomass power systems, you know the challenges – high temperatures and corrosive acidic conditions, to name a few. This is where Alleima’s materials expertise can help.
With deep experience in renewable fuel applications, we help you select solutions that improve efficiency, extend equipment lifetime and support the financial viability of your products.
Thermo-chemical conversion processes
Most bioenergy is produced through the chemo-thermal conversion of biomass – that is, plant, algae material or animal waste. This is typically done through combustion, gasification or pyrolysis.
- Combustion is the most well-established method, used to generate heat for electricity or direct heating.
- Pyrolysis breaks down biomas in the absence of oxygen, producing bio-oil that can be refined into biofuels.
- Gasification creates syngas, which can be processed into liquid fuels or other valuable products
These processes – especially when combined with high temperatures and reactive gases – create extremely tough conditions for boilers and production equipment.
That’s why we offer a wide range of corrosion-resistant (CRA) and high-temperature (HT) alloys, as well as industry-leading composite tube materials designed for these harsh conditions.
Applications:
- Heat exchanger tubes in Reactor Effluent Air Coolers (REACs)
- Heat exchangers tubes in feed/effluent systems and gasifiers
- High-pressure steam piping and biomass boilers
