As plants move towards full unit control, Jochen Geiger of Ametek Process Instruments provides an overview of how the latest sulphur plant analysers are providing greater insight into sulphur plant operations.

First Quantum Minerals Ltd. has contracted with MECS, Inc. (MECS), a subsidiary of Elessent Clean Technologies, for the Kansanshi smelter expansion at the Kansanshi mine at Solwezi. MECS’ scope of work will include a redesign of the existing sulphur-burning sulphuric acid plant into a copper smelter off-gas recovery sulphuric acid plant. This transition to a copper smelter off-gas recovery acid plant will enable First Quantum to reduce emissions from the existing copper smelter, increase production at the mine, and supply more copper to the global market, which will enable the adoption of greener technologies. MECS’ design for First Quantum incorporates proprietary technologies such as MECS® catalyst for low emissions and high conversion, Brink® mist eliminators, ZeCor® alloy towers and pump tank and UniFlo® acid distributor technology for operational reliability and efficiency.

Venkat Pattabathula , a member of the AIChE Ammonia Safety Committee, reports on the American Institute of Chemical Engineers’ Safety in Ammonia Plants and Related Facilities Symposium, held in Munich, Germany, from 20-24 August 2023.

The possible failure of refractory in a Claus unit is a concern to both licensors and operators of Claus units. Bob Poteet of WIKA discusses a novel and easy way to monitor the shell temperature of the Claus thermal reactor using proven technology and highlights the benefits a purge-less thermocouple system for high temperature measurement.

In this case study Johannes Derfler of AGRU Kunststofftechnik reports on how a new condenser design, engineered by OMV and INWA AG using PFA sheets from AGRU, was implemented at OMV refinery in Austria to address maintenance problems due to corrosion of the wet sulphuric acid (WSA) condensers and the follow-up units. As a result of the renovation, maintenance costs have been cut in half, while both maintenance intervals and overall operational safety has increased.
