The SRU Interactive Plant Diagram is Released

A Sulfur Recovery Plant serves to convert hydrogen sulfide (H₂S) in an incoming gas stream into elemental sulfur. Sulfur recovery plants are required to recover 95 to 99.99% of the total sulfur that is introduced into the plant. Emissions regulations are becoming more stringent with each year that passes, which is why high-quality industrial analysis equipment in Sulfur Recovery Plants is of major importance.

Applied Analytics provides a trusted and highly proven portfolio of analytical solutions for the sulfur recovery unit (SRU), where hydrogen sulfide is converted to elemental sulfur by the Claus process (or others). Our gas analyzers are used to improve the efficiency of conversion to elemental sulfur, prevent process upset, monitor SRU emissions, and detect hazardous conditions in sulfur storage pits.

AAI prioritizes the safety of our analyzers as well as the safety of those operating them. AAI’s SRU product line utilizes fiber optics to transmit light to and from the flow cell, allowing the electronics to be housed in a separate enclosure that is protected from the gas flow. AAI’s solid-state technology is a clear benefit in the corrosive environments it is designed for. The full-spectrum diode array analyzer responds rapidly to wide fluctuations in concentration of the analytes (such as: H₂S, SO₂, COS, CS₂). Some of the AAI SRU systems also incorporate monitoring of CH₄, CO₂ and H₂ — all seamlessly integrated by using the same controller and sampling system.
