Sulfatech

High-Performance Bioreactor for Anaerobe Applications

SULFATECH is an anaerobic gas scrubber used to sweeten sour gas in oil refineries and remove harmful sulfur emissions from gas in “waste to energy” projects fully biologically.

Advanced biological solutions for controlling sulfur emissions

Our proven SULFATECH System offers an efficient, cost-effective solution for reducing sulfur emissions. It eliminates over 99.5% of H2S and SO2. Unlike amine treatment, thermal oxidation, or caustic scrubbing, AZZURO’s technology handles H2S, SO2, COS, CS2, and mercaptans with higher reliability and lower maintenance. It also comes at a significantly reduced 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

An adaptive, self-regulating process that operates without chemicals and at ambient temperature and pressure.

Reliability

Provides consistent performance with few moving parts, ensuring extremely high reliability and minimal maintenance.

Versatility

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

Cost Savings

Allows for simple installation, minimal disruptions to operations, and reduced 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. Then, it pumps the gas into an aerobic biotrickling filter, which oxidizes the H2S into sulfuric acid (H2SO4).

The biogas flow remains in the anaerobic zone, where a “biological slurry” washes it to absorb and dissolve the H2S. The aerobic biotrickling unit drains 3-5% sulfuric acid, which is then recirculated into the biogas washing chamber. This chamber, still containing the biological slurry, is ready to scrub the H2S out of 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.

Pollutants

Hydrocarbons

Hydrocarbon recovery is best served with our bioreactor versus amine or caustic scrubbing—thanks to higher reliability, reduced maintenance and lower capital cost.
