Applied Analytics Analyser for Feed Forward Control in Sulphur Recovery
The efficiency of sulfur recovery, a procedure of utmost importance in many industrial processes, has gradually improved over the years. In maximizing this efficiency, control over oxygen input is paramount. Proper control in this respect requires accurate monitoring of H2S levels in acid gas; this in turn necessitates consideration of certain parameters such as time delay between measured signals from the beginning and the end of the process, or the extreme variation of feed gas concentrations throughout the process. It is has been demonstrated that feeds forward control in conjunction with tail gas control in sulfur recovery units drastically increases efficiency of recovery.
Applied Analytics' Feed Forwards Analyser (FFA) monitors the H2S concentration in feed gas or acid gas (H2S 0-100%) via a direct UV spectroscopic technique. The signals obtained in this method are used to control oxygen input to the SRU (Sulfur Recovery Unit) in question, as well as continuously analyzing and evaluating process effectiveness. Applied Analytics Analysers respond extremely rapidly to high fluctuations of H2S concentration while easily correcting for pressure and flow variations in the stream.
Some of the advantages of integrating an Applied Analytics Analyser include:
Safety of operation and Analyser components:
H2S, particularly at high concentration, is extremely toxic and corrosive. Applied Analytics' FFA 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. Applied Analytics prioritizes the safety of our Analysers as well as the safety of those operating them.
No moving parts:
Applied Analytics' solid state technology is a clear benefit in the corrosive environments it is designed for.
Fast response and auto-compensation:
The full-spectrum diode array FFA Analyser responds rapidly to wide fluctuations in concentration. The instrument also automatically compensates for pressure variation by continuously checking measurement point pressure against calibration pressure.
Flexibility:
If necessary, the system can incorporate infrared detection for monitoring concentrations of CH4 and CO2 all integrated and using the same controller and sampling system.
