Redox Sulfur Recovery Desulfurizer, also known as Redox Sulfur Recovery Desulfurizer, is a liquid-phase desulfurization technology based on chelated iron solutions. It efficiently removes hydrogen sulfide (H₂S) from gas streams and converts it into elemental sulfur (S) through a redox reaction cycle, enabling resource recovery of sulfur.

This process operates under ambient temperature and pressure, supports continuous operation, and is regenerable, making it one of the most environmentally friendly and efficient tail gas treatment and sulfur recovery technologies in the petrochemical industry.

Main Uses:

Removal of H₂S from gas streams to prevent equipment corrosion and environmental pollution

Sulfur recovery for integrated resource utilization

Compliance with strict environmental regulations, especially for H₂S emission control

Application Scope:

Tail gas desulfurization in petroleum refining units, such as hydrocracking, fluid catalytic cracking (FCC), and coking units

Natural gas processing and purification, suitable for both onshore and offshore gas fields

Desulfurization and sulfur recovery in industries such as coal chemical, coking, and syngas production

Purification of renewable gas sources, such as biogas, landfill gas, and anaerobic digester gas from wastewater treatment plants

Treatment of low-concentration sulfur-containing waste gases in environmental applications, especially well-suited for fluctuating conditions or intermittent gas sources
