Perennial Energy – Biogas Processing Systems

A design and manufacturing company specializing in biogas processing systems and equipment

About the Company:

Perennial Energy (PEI) is a design and manufacturing company specializing in biogas processing systems and equipment. If your project requires utility flare systems, enclosed flare systems, gas handling systems, blower systems, or compressed gas systems PEI has the pre-engineered, guaranteed system for your application.

In 1980, PEI was developing the science of processing, treating, and utilizing biogas. Since then, they have designed and manufactured fully integrated waste gas co-generation systems, gas boiler and thermal delivery systems, gas destruction systems, and gas handling systems for landfill, agricultural, municipal WWTP, and industrial markets. For over 30 years, they have “set the pace” for quality systems pre-engineered to meet your system requirements.

About the Solution:

PEI designs and manufactures Biogas Processing Systems (Compressor Skids, Blower Skids, Chiller Skids) to extract / receive waste gases from landfills, digesters, and other sources. Systems provide maintainable inlet and discharge pressures to satisfy process requirements as well as gas stream moisture removal and temperature conditioning. Systems range from basic waste gas extraction and combustion to multi-pipeline gas-to-energy projects. Perennial Energy classifies Biogas Processing Systems into two categories: Gas Handling Systems and Gas Compression Systems.

Gas Handling Systems are utilized by sites with basic gas processing requirements. These systems typically have a lower discharge pressure requirement, less than 3psi, and use centrifugal blowers.

Gas Compression Systems are utilized by sites with more aggressive gas processing requirements. These systems typically have a higher discharge pressure requirement, greater than 3psi, and use positive displacement compressors.

PEI Biogas Processing Systems are designed per site project requirements, and are most often provided as completely pre-engineered, pre-packaged, pre-conduited, pre-wired and factory pre-tested. The motor control centers, and digital logical control systems are usually provided on the skid-mounted system, having been designed specifically for the site requirements.

    Solution Strengths, Weaknesses and Critical Indicators

    Anaerobic Digester Associated Technology:

    NOTE: There are several technology types that are used as part of an integrated manure management system that includes an anaerobic digester and are not applicable to manure management in other cases. The impact of these technologies on the critical indicators are represented as those of an entire anaerobic digester system.


    • Long usable life and can be run reliably
    • Creates energy and generates environmental credits
    • Requires proper preparation of the feedstock
    • Requires other technologies for energy utilization
    • Requires other technologies for digestate handling
    • Proper feeding & system monitoring is required to avoid system downtime
    • Proven technology for odor control, GHG reduction and pathogen reduction

    Newtrient Comments/Opinions:

    Perennial Energy has recently been added to the Newtrient catalog. Newtrient will continue to work with Perennial Energy to further refine the cost and performance information on their solutions. Newtrient will update this entry as more information becomes available and as new commercial dairy installations come online.
