Introduction

Digester Gas Storage, Transport & Flaring Solutions

What Kind of Digester Gas Solutions Do We Offer?

Under the Shand & Jurs Biogas brand, we offer a complete “Gas Train”—an end-to-end solution that manages digester gas from production to destruction. Our portfolio includes:

Transport & Gas Conditioning

Systems designed to clean, dry, and safely convey gas, including:

  • Sediment Traps
  • Foam Separators
  • Drip Traps (manual & automatic)
  • Thermal Shut-Off Valves

These components remove moisture, solids, and foam—protecting downstream equipment.


Flaring & Gas Destruction

Open "Candlestick" Flares (e.g., 97301) for simple waste-gas burning.

Enclosed Burners (e.g., 97311) for smokeless, high-temperature destruction near population centers.

Flame Arresters

Critical devices like the 94306 prevent flame flashback into the digester tank—one of the most essential pieces of biogas safety infrastructure.

Shand & Jurs Model 94306 Vertical End-of-Line Flame Arrester

Gas Safety & Storage

Pressure/Vacuum Vents (e.g., 94020) to protect digesters from structural failure.

Digester Covers with position indication for monitoring gas storage volume.

02

Where Are These Solutions Used?

These systems are standard across Wastewater Treatment Plants, Landfills, Dairies, and Breweries.

01

Key Applications

  • Anaerobic Digestion & methane production.
  • Odor Control systems
  • CoGeneration / Combined Heat & Power (CHP) using biogas to fuel boilers, turbines, or generators.
02

Services

  • On-site Safety Surveys for compliance evaluation.
  • Start-Up & Commissioning for flares and gas train systems, ensuring proper burn ratios and performance.
03

Why Are Digester Gas Solutions Critical?

Digester gas is valuable, but also explosive, corrosive, and environmentally regulated.

Safety — Explosion Prevention

Without flame arresters and properly tuned vents:

  • Flashback from the flare can travel back into the digester.
  • Pressure spikes can rupture tanks.
  • Both scenarios pose catastrophic safety risks.

Equipment Protection

Biogas contains:

  • Moisture
  • Hydrogen sulfide (H₂S)
  • Solids & foam

These destroy downstream components without proper traps and separators.

Environmental Compliance

Methane is a potent greenhouse gas. Facilities must:

  • Burn excess gas
  • Meet EPA emissions standards
  • Avoid atmospheric venting

Our flaring systems ensure complete, clean combustion.

Introduction to Digester Gas Solutions

Transforming waste into renewable energy requires a system built for safety, reliability, and efficiency. In anaerobic digestion—whether at a municipal wastewater plant, a landfill, or a dairy—methane is both a valuable fuel and a hazardous substance.

Cognesense delivers the industry’s most complete portfolio of Digester Gas Storage, Transport, and Flaring solutions. Powered by the proven engineering of Shand & Jurs Biogas, we provide the entire Gas Train—a fully integrated system that collects, conditions, conveys, and safely destroys or utilizes biogas.

How It Works & Key Advantages

01

The Safety First Gas Train

Every system begins at the digester.

  • Pressure/Vacuum Vents protect the tank from collapse or over-pressure.
  • Flame Arresters prevent fire from traveling backwards through the pipeline into the digester—a critical life-safety function.
02

Cleaning & Conditioning the Gas

Biogas is inherently “wet” and dirty.

Our Sediment Traps, Foam Separators, and Drip Traps remove moisture, corrosive condensate, and particulates before the gas reaches your boilers or CHP engines—dramatically extending equipment life.

03

Efficient Flaring & Environmental Protection

If biogas cannot be used, it must be destroyed. Our flaring systems provide:

  • Stable Pilot Ignition
  • Stoichiometric Combustion
  • Smokeless Operation
  • High efficiency, even in variable wind conditions.

This ensures compliance with environmental regulations while minimizing visible emissions.

04

Superior Seal Performance

Only Shand & Jurs vents use ExpandaSeal™ technology, which:

  • Uses internal tank pressure to enhance the seal.
  • Minimizes fugitive methane emissions.
  • Reduces Odor
  • Preserves valuable gas for energy recovery.

Installation & Retrofit Considerations

Skid Mounted, Plug and Play Options

We offer turnkey skids where:

  • Traps
  • Valves
  • Piping
  • Instrumentation are prebuilt and tested at our factory—reducing field installation time and errors.
Corrosion & Material Options

Because biogas streams often contain H₂S, components are available in:

  • Stainless Steel
  • Aluminum
  • Exotic Alloys
  • PTFE & corrosion-resistant coatings

This ensures long-term reliability in harsh environments.

Why Cognesense?

Cognesense is the home of Shand & Jurs, the global authority in digester gas safety since 1922.

While some suppliers offer isolated components, Cognesense is the single source for a fully engineered Gas Train—from relief vents to flare tips.

Our Advantages Include:
  • Perfectly matched system components.
  • American-made reliability.
  • Deep expertise in gas handling and safety.
  • A holistic approach that eliminates compatibility issues.
