Maximizing Biogas Production Efficiency with Desiccant Dryers

Regarding new renewable energy solutions, Biogas has emerged as a promising alternative to fossil fuels commonly used worldwide today.

While its production offers significant environmental benefits, one key challenge is managing the moisture content in the biogas stream.

What is Biogas?

Biogas is a biofuel that naturally occurs from the decomposition of organic waste. In an anaerobic environment, the organic waste starts to break down and releases gasses such as methane, carbon dioxide, hydrogen, and/or ammonia. These gas mixtures can be used as a source of renewable energy for heat and electricity, helping to reduce carbon emissions and create a sustainable energy source.

But again, managing moisture content in the biogas stream is the challenge—this is where we think our Van Air Biogas dehydration technology comes into play the best, offering energy-efficient solutions for biogas dehydration and helping enhance the overall production efficiency.

Case Study & Examples

We first encountered this challenge while working with different engineering firms to help design a system where we can essentially fit a series of PLD Pipeline Deliquescent Natural Gas dryers and filter into an existing Biogas production plant using a TEG system.

New biogas treatment facilities have noticed that when a biogas production facility is first started up, there is excessive moisture in the lines (which is not found after they’re up and running for a while).

This created an issue where the gas was too saturated to be produced as a sales gas. So, they needed a system that could replace these existing systems to keep moisture control in the biogas stream. When Van Air provided them with the PLD natural gas dryer system, it helped remove extra moisture that was not picked up through the TEG system during the initial startup.

Other benefits of removing the excess moisture include preventing any type of corrosion from starting to form on the equipment, which could cause damage. Removing moisture also helps protect any downstream equipment, such as compressors or engines.

We have also provided these plants with an Emergency Shutdown Drying solution. If their TEG system were to fail, our industrial biogas solution would be available with the turn of a bypass valve.

There are many cases where a shutdown can cause plant equipment damage, operational downtime, and a reduced gas quality. With our Emergency Shutdown Dryer system in place, there would be no need for downtime as our system will already be in place, and with the flip of a valve, you will be actively drying immediately.

The Future of Sustainable Energy Production

We see industrial biogas solutions incorporating deliquescent desiccant dryers as helping pave the way for more sustainable energy production worldwide. Companies are now also seeing the benefit of being able to produce high-quality biogas that can be used for not only electrical generation but also heating and - eventually - vehicle fuel.

This shift in promoting green energy from waste not only helps in reducing dependence on fossil fuel but also promotes the recycling of organic waste, thus minimizing landfill use and methane emissions.

Integrating biogas dryers will help ensure compliance with environmental regulations and standards, further solidifying biogas as a viable eco-friendly solution.

Conclusion

As the world moves towards more sustainable energy solutions, the role of Van Gas PLD Dryers in biogas production cannot be overstated. By ensuring effective moisture control in biogas, our dryers will not only help in enhancing fuel quality and operational efficiency but also help contribute to show all the environmental benefits. Investing in these Biogas dehydration technologies will be a critical step in shaping the future renewable energy landscape.
