Frequently Asked Questions

How long does one charge of desulfurization agent last?

Service life depends on inlet H₂S concentration, gas flow rate, and bed volume. For typical agricultural biogas (1,000–2,000 ppm H₂S), a properly sized bed lasts 3–6 months. We provide free bed sizing calculations with every inquiry — just share your gas volume and H₂S concentration.

Can the media be regenerated to extend its life?

Yes. The spent media can be partially regenerated by controlled air exposure (oxygen-assisted regeneration). Typically 2–4 regeneration cycles are achievable before the media needs full replacement. We supply operating guidelines for safe regeneration procedures with every order.

Is the spent media hazardous waste?

Spent media contains iron sulfide compounds. In most jurisdictions it is classified as non-hazardous solid waste and can be landfilled. However, it must be wetted before disposal to prevent pyrophoric ignition risk. Always follow local environmental regulations. We provide SDS and disposal guidance documentation with all shipments.

What inlet H₂S concentrations can this product handle?

Our standard media handles inlet concentrations from below 500 ppm up to 5,000 ppm H₂S. For very high-concentration streams (>5,000 ppm), we recommend a two-stage setup or using our liquid desulfurization solution as the primary treatment stage.

What is the minimum order quantity and lead time?

Minimum order is 500 kg (1 pallet). Standard lead time is 7–14 business days for stock items; customized particle sizes or large-volume orders may require 3–4 weeks. We ship globally via sea freight and air freight with full export documentation.

Do you provide technical support for system design and installation?

Yes. Our engineering team provides bed sizing calculations, system design recommendations, and troubleshooting support via email and video call at no extra charge. On-site commissioning support is available for large projects (fees apply). We are a manufacturer, not just a reseller — our team understands the chemistry and application deeply.
