The trend for multicomponent analysis of emissions from sulphur recovery units is becoming more widespread. David Inward of Sick reports on a recent field trial to test the suitability of a hot extractive infra-red analyser for this application. In addition to reliably measuring and reporting emissions to air, the analyser is also capable of contributing to reducing overall tail gas emissions by supporting enhanced optimisation of the thermal oxidiser.

Tightening regulations and growing global competition are increasing the pressure felt by sulphuric acid plant operators to reduce emissions and improve energy output. Conservation of energy is a continuous focus for operators, and environmental communities have grown more vocal in their desire for greater emissions oversight. In this article, DuPont Clean Technologies examines simple, tried, and true tactics, as well as new products and designs that can be incorporated into existing plants to address operating efficiency and emissions and to help to prolong the life of the plant.

Sulphur’s annual survey of recent and planned construction projects in the sulphuric acid industry includes several large-scale acid plants both for phosphate processing and to capture sulphur dioxide from smelters.

Ron Olson of The Sulphur Institute considers sulphur’s important role in plant health.

Legislation to control emissions of sulphur dioxide continues to tighten, via vehicle exhausts, and refinery and smelter emissions, leading to increased recovery of both sulphur and sulphur dioxide.
