Sulfur Recovery Unit

Application Overview

The Claus process recovers elemental sulfur from gaseous hydrogen sulfide through a high temperature reactor and subsequent catalyst processes. Temperature is a primary process variable, but more importantly temperature measurement is critical for the overall safety and reliability of the reactor. As standard process temperatures rise through the use of oxygen enrichment and reach maximum capabilities of the refractory, it becomes increasingly important to have accurate and reliable temperature indication. Temperature is also critical for startup and shutdown processes.

The Delta Controls Benefit

Industry standard purged thermocouples for sulfur recovery temperature measurement
Unique pyrometer design prevents occlusion and sight path blockage issues
Only manufacturer to provide both infrared pyrometry and thermocouple technologies for sulfur recovery service
Sulfur-specific design maximizes measurement accuracy
