  • Model 900 Air Demand Analyzer
    900 Tail Gas-Air Demand Analyzer

    In the past, conventional Claus sulfur recovery processes were adequately controlled on the basis of ratio or excess process air. However, 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 5% H2S or SO2), to ensure correct response to such conditions. Data on COS and CS2 concentrations are also increasingly used to monitor catalyst and overall sulfur plant performance.

  • Model 930 H2S in Sulfur Pit Analyzer
    930 H2S in Sulfur Pit Analyzer

    In many sulfur recovery units, produced sulfur is stored in liquid form in sulfur pits. Operators are increasingly aware that sulfur pits present potential danger to plant personnel and overall plant safety. It is therefore critically important to monitor H2S in the vapour space of sulfur pits to ensure that it remains below the Lower Explosive Limit (LEL) (4.3% by volume).
