Sustainability

During the development of the Sulaway® process, the basis was to make a system which would clean gas without producing any waste materials. Existing H2S removal processes all have waste products or high running costs due to continuous requirement of, for example, fresh water, filter replacements or activated carbon. The operational costs are relatively high as well, due to destruction or removal of the corrosive waste products. This is a difficult, time consuming and therefore expensive job. The production of biogas itself is already a sustainable process and an alternative energy source. The Sulaway® unit only adds to this sustainable process by providing usable output with no waste.

Gas vs. Electricity

The trend in sustainable energy production is that (bio) gas production facilities all have the goal to upgrade the gas and create electricity with it. However, we believe this does not have a future in many countries and does not present a viable business case.

Low electricity price, low energy efficiency and lack of storage possibilities for electricity make it more interesting to produce and use green gas. The best opportunity for gas producing facilities, such as large cattle farms or wastewater facilities is to seek a nearby user of natural gas and supply the cleaned gas from the Gazpack unit to the gas turbines of that user. Simply mixing the natural gas with the cleaned (bio) gas will leave the total gas flow within the boundaries of turbines and severely decreases the usage (and costs) of the natural gas.

Green image

The best example of sustainability however can be found in the fact that reducing the natural gas usage and increase its green gas usage will give your company the opportunity to have a green image, a priceless but valuable appearance in today’s world. This statement is enforced by the benefits of the Gazpack system on both technology and environment.

  1. Reduction of toxic exhaust gas particles: NOx CO and SO2
    Clean biogas produced by the Sulaway® unit burns better than raw biogas, reducing the dangerous and toxic exhaust particles in the air.
  2. Decrease of carbon dioxide (CO2) content
    The gas purifier does not only remove Sulfur but is also capable of removing CO2 from the biogas reducing its carbon footprint.
  3. Lethal Sulphur (H2S) converted into a usable product
    Sulfur is an unusable product when mixed within the gas. When removed using other methods Sulfur is often bonded to a carrier. Carrier and Sulfur are often burnt by waste removal companies producing a high amount of toxic gas particles in the air. Gazpack removes the Sulfur and generates a high concentrated H2S gas stream to be used for different purposes. The carrier is regenerated to be used for the next cycle of cleaning gas.
  4. Solid build
    Gazpack installations are build according to the latest standard and industrial, safety and environmental requirements.
  5. No more odor and gas leakages
    The Sulaway® unit is completely enclosed, leak free and equipped with state of the art safety devices ensuring a safe working environment.
  6. Sulabead® is mechanically strong
    Oxygen, Cyanide and other aggressive elements do not harm the Sulabead®
  7. Increased fertilizer quality ( for biogas only)
    The ammonium removed from the air of the stables produced by the scrubber can be used as a fertilizer to significantly enhance the quality of manure.
