Biogas Upgrading Plant - BioBasic

The simple approach to turning biogas into bio-methane is realized with Pentair’s BioBasic, which recovers bio-methane as a replacement for fossil based natural gas while meeting quality requirements in a cost-efficient solution.



Biogas is a key renewable energy source. Pentair is your partner in turning waste streams into sustainable energy solutions and valuable revenue streams. Pentair’s BioBasic is easily integrated with upstream and downstream equipment providing high operational readiness and availability (uptime). The BioBasic is delivered to site after a short and optimized fabrication time allowing for rapid project execution.

The bio-methane can be injected into existing gas grids as a sustainable replacement of fossil natural gas or it can be utilized as fuel – either as Renewable Compressed Natural Gas (Renewable CNG) or Renewable Liquid Natural Gas (Renewable LNG). Utilizing bio-methane eliminates fossil fuel based carbon emissions in industrial and domestic environments, transportation, electricity and heat production.

Did you know that our membrane and amine based upgrading technologies are both compatible with our efficient CO2 technologies? Pentair can provide you with the unique opportunity to add another carbon intensity lowering revenue stream to your biogas plant: food-grade CO2. Needless to say, our products help you control the impurities to produce bio-methane in the most efficient process – with zero methane slip.

Pentair’s Sustainable Gas Solutions specializes in biogas upgrading and CO2 recovery systems. With over 1500 installed plants, including more than 40 biogas upgrading systems, Pentair’s dedication to this core business is widely recognized within the industry. Our R&D department is constantly researching emerging technologies for improving the efficiency and effectiveness of our biogas upgrading solutions. Most importantly: we are there for you when your system is operating -- with global service hubs and dedicated technical support. We diagnose and optimize whenever you need us to keep your plant up and running! That’s why Pentair!

In the pre-treatment, water and contaminants are removed from the biogas. The basic biogas treatment allows for modest contaminations levels of hydrogen sulfide (H2S) and volatile organic compounds (VOC) -- for bulk removal of H2S or VOC’s, other options are available. After pre-treatment, the biogas is compressed to the most OPEX and CAPEX efficient pressure for that allows for removal of CO2. The membranes then remove the CO2 from the methane to meet the required Renewable Natural Gas (RNG) specifications. Upgraded biomethane can be injected into the national grid or further processed to renewable CNG or LNG.
