The Sulphur Institute (TSI) held its World Sulphur Symposium in Edinburgh from April 25th to 27th.

With the challenges facing the global refining industry, refiners should review their current practices to see how they can stay competitive and continue to thrive in today’s market. This means improving operational efficiencies and producing products at a lower cost, whilst ensuring performance and safety. Brian Visioli of Evonik explores the development of catalyst reuse and how recycled hydroprocessing catalysts can be successfully applied in tail gas treating units to deliver cost and performance gains.

As part of the expansion of the Shah gas plant (SGP) in the United Arab Emirates, a new 12-inch pipeline was designed and commissioned in January 2020. Hassa Al Mulla, Ravi Srinivas and Alsail Al Jaberi of ADNOC Sour Gas highlight the best practices implemented in the newly commissioned liquid sulphur pipeline.

Incorporating sulphur into polymers is known to improve their properties. New research is looking into the varied world of sulphur co-polymers, unlocking new materials for batteries, structural applications and clean technology.

BASF is challenging traditional catalyst shapes and performance relationships by introducing a radically new shaping concept resulting in materials with step change properties and performance. This innovative concept using 3D-printing technology is applicable to a wide range of reactions in the chemical industry and BASF is using sulphuric acid catalysts as the pilot to pioneer new ground.

Inshan S Mohammed of Sulfur Recovery Engineering shares the lessons learned from an emergency shutdown of an MCRC sulphur recovery unit in the middle of a cold Canadian winter where temperatures can be -30°C.

Liquid fuels will be with us for decades to come, but refiners will be pushed to decarbonise their activities, via greater use of biofuels, and green/blue hydrogen use.

The sulphuric acid process is virtually carbon free and, as such, it is important to consider the energy requirements of the associated industrial complex before deciding upon what form the energy should be exported from the acid plant. In this article, Stefan Braeuner, Stefan Mohsler and Anne Mohsler of Metso Outotec use case studies to exemplify the need to fully analyse the local conditions at site before a decision is taken on a specific flowsheet.

Lithium sulphur batteries have many advantages over conventional lithium ion batteries in terms of energy density, and they also avoid the use of costly cobalt, but they deteriorate rapidly and cannot be recharged as frequently. However, recent advances in Li-S batteries could overcome this problem and lead to widespread adoption.

Most processes involving sulphur, from smelting to refining, produce sulphur dioxide as a by-product. Regulations continue to tighten on industrial SO2 emissions worldwide, leading to greater recovery of sulphur and sulphuric acid at these sites.
