Sulfatech

High-Performance Bioreactor for Anaerobe Applications

SULFATECH is an anaerobic gas scrubber that sweetens sour gas in oil refineries and removes harmful sulfur emissions from gas in “waste to energy” projects using a fully biological process.

Advanced biological solutions for controlling sulfur emissions

Our proven SULFATECH System provides an efficient and cost-effective way to reduce sulfur emissions. It removes over 99.5% of H2S and SO2. Unlike amine treatment, thermal oxidation, or caustic scrubbing, AZZURO’s technology reliably handles H2S, SO2, COS, CS2, and mercaptans with lower maintenance. Additionally, it comes at a significantly lower cost.

Why Sulfatech

Aerobe bioreactor used to remove sulfur emissions

Effectiveness

Eliminates over 99.5% of H2S and other toxic sulfur compounds.

Capacity

Handles flow rates up to 20,000 cfm and H2S concentrations up to 20,000 ppm.

Technology

It’s an adaptive, self-regulating process that works without chemicals and operates at normal temperature and pressure.

Reliability

It delivers consistent performance with few moving parts, which ensures high reliability and low maintenance needs.

Versatility

Features a modular design that is easily configurable for various applications.

Cost Savings

It allows for easy installation, minimal disruptions to operations, and lower steam consumption, enabling CAPEX recovery in as little as 24 months.

Safety

The anaerobic system keeps all gas free of oxygen, reducing explosion risk and avoiding undesirable conditions.

Sustainability

No chemicals or annual media change-outs reduce your carbon footprint and produce no waste by-products.

Compliance

Forward-thinking design meets increasingly stringent government regulations on sulfur emissions, ensuring compliance and environmental safety.

The Sulfatech Process

Patented Technology

First, SULFATECH absorbs H2S from biogas or sour gas in an anaerobic chamber. Next, it pumps the gas into an aerobic biotrickling filter, where the H2S is oxidized into sulfuric acid (H2SO4).

 

The biogas flow stays in the anaerobic zone, where a “biological slurry” washes it, absorbing and dissolving the H2S. The aerobic biotrickling unit drains 3-5% sulfuric acid, which then returns to the biogas washing chamber. This chamber, still containing the biological slurry, is ready to scrub H2S from the methane (CH4) again.

To maintain the correct sulfuric acid concentration and salt level, a small percentage of the flow is refreshed with potable water.

Finally, clean gas exits the unit, and the process starts again. Because of the anaerobic and acidic environment, the biological reduction of methane is minimal.
