Summary
Fugitive dust emissions during the handling and storage of formed sulphur can result in negative environmental impacts and under specific conditions result in an explosion hazard. Enersul has developed a dust suppression system specifically targeted at controlling sulphur dust particles. The Enersul SafeFoam Transfer System (STS) reduces sulphur fines at critical transfer points throughout any sulphur handling system, resulting in a significantly safer and more environmentally friendly sulphur handling system.Abstract
Sulphur deficiency in arable soil has been becoming a major concern in the agricultural industry in recent years. Factors contributing to sulphur deficiency in soils include the fact that more sulphur is being removed from the soil due to the increase in agricultural production and less sulphur is being added back into the soil due to the use of sulphur-free fertilizers and lower sulphur dioxide emissions throughout the world.

IPCO provides an update on its latest activities, with flexible processes enabling IPCO's project for the first drum granulation plant in Europe to remain on track despite unprecedented Covid-19 restrictions.Abstract
IPCO, one of the world’s leading suppliers of sulphur processing and handling systems, is working to deliver what will be its first mid-capacity drum granulation plant in Europe. The project, scheduled for commissioning in Q3/Q4 2020, remains on track despite restrictions imposed due to the coronavirus pandemic. Keywords: sulphur forming, drum granulation, Covid-19, sulphur granulator, SG30, SUDIC quality, SUDIC specification, sulphur handling, sulphur processing, sulphur degassing, Rotoform, sulphur pastillation, Industrial Internet of Things, IIOT, Life Cycle Concept, IPCOSummary
Kreber's R&D department has been researching the prilling of sulphur in pursuit of the ideal process. In this article, T. Nieboer of Kreber recounts the history of prilling up to today, tracing the developments and highlighting the challenges that still remain.Abstract
Legend has it that one night in 1782, William Watts, a plumber from the city of Bristol in the UK was walking home after a long night of drinking ale. On his way home he decided to take a rest near St Mary Redcliffe church, which he had worked on, helping to renovate the lead roof.

With increasing frequency, companies that have molten sulphur on site must put environmental controls on the vent streams from molten sulphur pits, storage tanks and loading operations. This article* describes the typical characteristics of molten sulphur vent gas streams as well as some of the important chemistry related to these systems in caustic scrubbers. Solids deposition issues observed in the field with caustic scrubbers operating on actual molten sulphur vent gas streams are presented. Design and operational strategies to mitigate plugging in molten sulphur vent gas scrubbers are also summarised in this article by D. J. Sachde, K. E. McIntush, D. L. Mamrosh, and C. M. Beitler of Trimeric Corporation.Abstract
The removal of hydrogen sulphide (H2S) from sour gas streams can be achieved with many different technologies, one of which is caustic scrubbing. Keywords: molten sulphur, sulphur storage and transport, caustic scrubbing, sulphur vent streams, solids deposition, plugging, molten sulphur pits, molten sulphur storage tanks, loading operations, elemental sulphur dissolution, caustic chemistry, salts precipitation, elemental sulphur deposits, gas-liquid contact, removal of sulphur solids, equipment, design strategies, operating strategies, adiitives, cleaning, Trimeric CorporationSummary
The removal of hydrogen sulphide (H2S) has become increasingly important as the oil and gas industry moves towards more efficient and sustainable production of lower emission clean fuels. BASF and ExxonMobil* have jointly developed a proprietary amine, OASE® sulfexx™, to help refiners and gas processors achieve sulphur removal targets while reducing their carbon footprint via lower energy consumption. This new solvent technology is suitable for low and high pressure applications and shows superior performance characteristics over generic and promoted MDEA formulations, as well as sterically hindered amines such as FLEXSORB™ SE and SE Plus.Abstract

Although amine solution foaming problems have been studied and reported extensively, direct correlations about the root causes of foaming have not been completely established. This article approaches the problems of foaming from a different perspective, rather than theoretical discussions, the topic is centred exclusively on Amine Experts' field-related experiences with amine foaming episodes.Abstract
Amine solution foaming is a phenomenon that has been intensively studied and reported elsewhere. Several foaming root causes have been determined throughout the years, however, the latest experiments suggest that the predominant mechanism for foaming is related to contaminants in the form of surface-active materials, or surfactants.

Sulphur demand in Australia has been boosted by the restart of the nickel leaching plant at Ravensthorpe, and new HPAL projects are under development, but a slew of new phosphate projects are not scheduled to consume more acid domestically.Abstract
In spite of having a population of only 25 million people, like Canada, Australia’s huge size and mineral resources make it a major international player across many industries. Australia’s economy is actually the world’s 13th largest, and more importantly it holds the world’s largest reserves of nickel and uranium, and the world’s second largest copper reserve after Chile (13% of all global copper).

There was a rapid increase in sulphuric acid demand for copper, uranium and nickel leaching from 1995-2015, but over the past few years growth in this sector has slowed dramatically. Now however there are signs that demand is starting to pick up again with several new projects under development.Abstract
Metal oxide ores are often treated with sulphuric acid to recover the metal as a soluble sulphate. This leaching process is a major consumer of sulphuric acid, accounting for just over 10% of all acid demand in 2018, and consuming over 27 million t/a of acid.
