Product Q&A
Q:Why is hydrogen sulfide harmful in biogas?
A:
H2S is corrosive to metal parts (engines, pipes, valves), toxic to humans at >10 ppm, and produces SO2 (acid rain contributor) when burned. Desulfurization is necessary for safe and efficient biogas use.
Q:How often do I need to replace the desulfurization media?
A:
For iron sponge: every 6-12 months depending on H2S load. For activated carbon: every 3-6 months. For biological systems: media does not need replacement; just maintain pH and nutrient levels.
Q:Can I achieve below 10 ppm H2S with a single-stage system?
A:
Yes. Iron sponge and activated carbon units can easily achieve < 10 ppm. Biological systems typically achieve 50-100 ppm without polishing. For < 1 ppm, use activated carbon as a second stage.
Q:Does desulfurization remove other impurities like siloxanes?
A:
No. Standard desulfurization targets H2S only. Siloxanes (found in landfill gas) require separate treatment using activated carbon or refrigeration.
Q:How do I know when the iron sponge media is saturated?
A:
Install a small H2S detector at the outlet. When the reading rises above your target level (e.g., 10 ppm), it is time to regenerate or replace the media. Also, the media changes color from brown (fresh) to black (spent).
