Accessories

The Brimstone™ series analyzers are based on UV spectrophotometry. They are designed to ensure quality, efficiency and compliance throughout the sulfur recovery process.

The Brimstone™ 943 is an on-line process analyzer designed for air demand control in sulfur recovery units (SRU). The equipment controls the ratio of H2S to SO2 to optimize elemental sulfur recovery.

This fast and accurate broadband UV analysis helps operators minimize SO2 emissions.
