A report on CRU’s annual Sulphur + Sulphuric Acid conference, which returned to being face to face meeting at the end of October 2022.

Temperature monitoring and measurement of the Claus thermal reactor in sulphur recovery units is one of the most challenging applications in the oil and gas industry. Recently, market interest in unpurged thermocouples has increased with the introduction of new unpurged thermocouple designs utilising alternative thermowell materials such as monocrystalline sapphire.

Sophisticated control of phosphates production is now possible thanks to the availability of real-time process analysers. We assess the range of technologies currently on the market and their key advantages.

As the industrial value chain for fertilizers and their raw materials manages its way through the unprecedented global Covid-19 pandemic, Metso Outotec’s Hannes Storch, Collin Bartlett & Marcus Runkel reflect on the range of digital tools installed by the company at its industrial reference plants globally.

Applied Analytics discusses potential improvements made possible with data and analytical measurements fed into improved mathematical models to produce a more proactive approach to control and better performance of sulphur recovery units, AMETEK Process Instruments explains the benefits of feed forward control, SICK reports on reliable continuous emission monitoring systems and WIKA introduces a new purge-free system to measure refractory temperature in the Claus reaction furnace.

Operating at the wrong synthesis operating pressure is always a tricky situation for any urea plant operator, knowing that operating at too high a pressure will lead to the pressure safety valves blowing off. The key is to measure the synthesis pressure in a reliable way.
