What is the typical pressure drop across a desulfurization vessel?

For clean media: 10-30 mbar. As the media becomes loaded with sulfur, pressure drop can increase to 50-100 mbar. Replace or regenerate media when pressure drop exceeds the blower's capacity.

Can I use the same system for different biogas sources?

Yes, but you must adjust retention time and possibly use a larger vessel if H2S concentration varies greatly. A pre-analysis of the new gas source is recommended.

AI-Powered supplier vetting

SummaryThe supplier is described as a combined company and a technology enterprise covering R&D, design, production, marketing, and after-sales service for dryers, desulfurization equipment, biogas engineering, and drying equipment. It holds ISO 9001 and SHE Audits certifications. Service procedures exist for supplier-service assessment, corrective and preventive actions, and complaint handling, but written records are absent for the latter two mechanisms. The supplier reports no overseas warehouses, showrooms, agents or branches, and no offline trade-show participation. It offers ODM, OEM for well-known brands, and broad customization services. However, no new product information was reported for the past year, and no SDK is available. Production capability is indicated by the stated manufacturing base and product production activities, although detailed capacity metrics are unavailable. Customer cases are not provided.

Supplier typeThe supplier is identified as a comprehensive technology enterprise with R&D, design, production, marketing, and after-sales activities, and its company type is explicitly classified as “Combined.”

CertificationsThe supplier reports holding SHE Audits and ISO 9001 certifications. These are explicit certification holdings relevant to management and quality systems.

Production capacityThe supplier explicitly states that it conducts production and manufacturing of large-scale dryer sets, desulfurization equipment, biogas engineering, and drying equipment, and identifies a production and manufacturing base in Weifang. Detailed production capacity, equipment, or output data are not provided.

Customization capabilityThe supplier explicitly provides customization from samples, customization from designs, full customization, minor customization, and flexible customization, in addition to ODM services. This demonstrates broad stated customization coverage.

Product Q&A

Q:Why is hydrogen sulfide harmful in biogas?

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?

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?

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?

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?

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).
