Brimstone 943 is a tail gas analyzer from Galvanic Applied Sciences that continuously measures the H2S and SO2 ratio in the tail gas of sulfur recovery (Claus) units. The measured H2S/SO2 ratio is fed back to air demand control, optimizing reactor efficiency and sulfur conversion. The sample is taken with a steam-jacketed probe and valve and conditioned in the cabinet.

The ATEX Zone 1 version is offered with a custom 316 stainless steel cabinet, 942 probe assembly and steam-jacketed 2-inch ball valve. A typical air demand application is configured for a range of 0 – 10% H2S and 0 – 5% SO2. Options such as remote commissioning support, a special gas run, NACE documents and FAT can be planned separately.
