Model 900 Tail Gas-Air Demand Analyzer

Overview

In the past, conventional Claus Sulfur recovery processes were adequately controlled on the basis of ratio or excess process air.  The development of new and modified sulfur recovery processes has dramatically changed the analytical requirements placed on the tail gas analyzer.  These applications require accurate chemical concentration data over wide dynamic ranges.  Selective oxidation processes may require the analyzer to control the H2S/SO2 ratio at values ranging from 1:7 to greater than 10:1.  In addition there is an increased need to provide reliable process data during upset conditions to endure correct response to such conditions.

 

AMETEK Process Instruments Model 900 Air Demand Analyzer was specifically designed to meet the more demanding analytical requirements of these new processes.  Used in conjunction with the ASR 900 sampling probe, the Model 900 ensures maximum data availability for optimum operation of all sulfur recovery processes.


Features

  • Uniquely capable of monitoring off-ratio applications
  • Reliable, trouble-free sampling
  • Automated zero gas calibration
  • Modbus serial interface with plant DCS
