    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.
