Agricultural Biogas Production and Use

Agricultural biogas produced in farm-based anaerobic digesters or covered lagoons can be used as a fuel source to power generator sets, or converted to compressed natural gas on-site or at third-party compressor stations through utility pipeline transmission. These processes help you save time and money and allow your facility to run much more efficiently. H2S removal systems are much more efficient and beneficial to your company's bottom line and convert agricultural biogas into a fuel source.

 

When used as a fuel source, the presence of H2S in the biogas will have a damaging effect on reciprocating or turbine engine life, increase maintenance costs, and shorten the time between rebuilds. Generator set manufacturers have begun setting limits on H2S concentrations as part of their conditions imposed on the user to maintain warranty coverage. This means that you need to partner with a company that understands the inherent challenges throughout the process. We work with you from design to implementation and are involved in every step in between. This allows your team to focus on their core work.

 

In order to meet sulfur dioxide emission limits on engine exhausts, H2S may need to be removed prior to combustion. In cases of extremely low general emission limits, where a catalytic converter is necessary, the H2S must be removed prior to combustion, or the life of the expensive catalyst will be reduced substantially. This means the system must be designed to meet the emission limits. Accordingly, all of our systems are designed to meet this need.

 

A well-designed system means that you won't be trying to make improvements on the fly just to get an okay result. Our systems work right from the start and provide amazing results. The impact that these systems have on the overall efficiency of the facilities in which they're in use is significant. You'll be pleasantly surprised by the positive impact your new disposal system will have on the optimization of your plant or agricultural firm.

 

If the biogas is converted to CNG, those specifications include very low limits on H2S. When the gas is transported via a utility pipeline to a CNG compression station, even lower pipeline specifications will have priority. Our team can help you prioritize your systems to ensure that you can create an efficient environment while meeting all regulations and industry standards. However you choose to approach your H2S process, we can provide systems and solutions that meet your needs. Unscheduled maintenance and repairs that take your systems offline will no longer be of concern once we've created the right system that's tailor-made for your facility's unique needs.

FAQs

 

What is Agricultural Biogas?

Agricultural biogas is a renewable energy source produced from the anaerobic digestion of organic materials such as crop residues, livestock waste, and other agricultural byproducts. This process, which occurs in the absence of oxygen, generates biogas that typically consists of carbon dioxide (CO₂), methane (CH₄), and hydrogen sulfide (H₂S). Agricultural biogas offers a sustainable solution for waste management while contributing to the global effort to reduce reliance on fossil fuels.

 

What Are Common Uses of Agricultural Biogas?

Agricultural biogas is a versatile energy source that can be used for various applications. It is commonly utilized to generate heat and electricity in combined heat and power (CHP) systems. In these systems, the biogas is burned to produce electricity, with the resulting heat captured and used for heating agricultural facilities or nearby structures. Additionally, agricultural biogas can be upgraded to biomethane, which can be injected into the natural gas grid or used as a transportation fuel. This makes agricultural biogas a sustainable energy source and a valuable commodity in achieving energy independence and reducing greenhouse gas emissions.

 

How is Agricultural Biogas Typically Produced?

Agricultural biogas is produced through anaerobic digestion, where microorganisms break down organic materials in the absence of oxygen. This process takes place in covered lagoons or digesters, which are specifically designed to provide the ideal environment for biogas production. Organic matter, such as crop residues or livestock manure, is placed into the digester, where it decomposes and generates biogas over time. This natural and efficient process allows agricultural operations to turn waste materials into a valuable energy source.

 

Why is H₂S Removal Essential in Agricultural Biogas Systems?

H₂S (hydrogen sulfide) is a common component of biogas that can harm agricultural equipment and the environment. H₂S is corrosive and can damage engines, pipes, and other machinery if not properly removed. Additionally, H₂S is toxic and contributes to air pollution, making its removal essential for environmental compliance. By implementing H₂S removal systems, agricultural biogas operators can protect their equipment, reduce maintenance costs, and ensure their facilities meet local and global emissions standards.

 

Are There Environmental Benefits of Using Agricultural Biogas?

Yes, there are numerous environmental benefits associated with agricultural biogas. The production and use of biogas help manage waste efficiently by converting organic materials that would otherwise contribute to pollution into a renewable energy source. Furthermore, using agricultural biogas reduces greenhouse gas emissions, as it captures methane—a potent greenhouse gas—before it can be released into the atmosphere. By replacing fossil fuels, biogas also contributes to reducing the carbon footprint of various industries and supports the transition to a more sustainable energy future.

 

What is the Role of H₂S Removal Systems in Agricultural Biogas?

H₂S removal systems are crucial for ensuring the safety and efficiency of agricultural biogas operations. These systems are designed to extract hydrogen sulfide from the biogas, preventing it from causing corrosion or damage to equipment and engines. By removing H₂S, these systems help maintain the performance of catalytic converters and other machinery, extending their lifespan and ensuring compliance with emissions standards. The removal of H₂S also enhances the quality of the biogas, making it more suitable for various applications, including injection into the natural gas grid.

 

How Do I Choose the Most Suitable H₂S Removal System for My Agricultural Biogas Facility or Business?
