Full Sulfur Recovery Catalyst Package for a Gas Processing Plant

Sulfur Recovery

99.5%+
Sulfur Recovery Rate
01

Project Scenario

A large Middle East gas processing plant with high-humidity, high-sulfur feed. The previous imported sulfur recovery catalyst powdered easily, organic sulfur in tail gas exceeded limits, and environmental acceptance failed.

02

Our Solution

Delivered a complete three-catalyst package — Claus main-reaction catalyst, tail gas hydrogenation catalyst, and organic sulfur hydrolysis catalyst — with moisture- and salt-poisoning resistance optimized via CAS materials-modification technology.

03

Project Results

  • Comprehensive sulfur recovery raised above 99.5% with COS organic sulfur hydrolysis ≥97%, fully resolving tail gas exceedance
  • mechanical strength greatly improved with no powdering or plugging, and start-up stability significantly upgraded.
