RSK and its subsidiary ADAS have developed a sustainable solution for the disposal of sulphur waste generated from a natural gas processing facility in Iraq. C. Teulon of RSK reports on the research that was carried out to test whether the waste sulphur from a biological sulphur removal process could be applied in agriculture to increase the quality and quantity of crops in Iraq.
Johnson Matthey and MyRechemical have formed an alliance to commercially develop waste to methanol technology. In this article, two different approaches to waste disposal and chemical production are analysed: a post combustion scenario with waste incineration and hydrogenation of the CO2 recovered from flue gas to produce methanol, and a precombustion approach with waste gasification followed by conversion of synthesis gas into methanol.
The latest developments in the recovery and commercialisation of fluorosilicic acid, rare earth elements (REEs) and uranium co-products associated with phosphoric acid production.
A consortium has unveiled plans to build one of the largest green hydrogen plants in the world in a bid to make Oman a leader in renewable energy technology. The $30 billion project is being developed by Oman’s state-owned oil firm OQ, green fuels developer InterContinental Energy and Kuwait government-backed renewables investor EnerTech. Construction is scheduled to start in 2028 in Al Wusta governorate on the Arabian Sea. It will be built in stages, with the aim to be at full capacity by 2038, powered by 25 GW of wind and solar energy. Two years has already been spent on solar and wind monitoring analysis for the development. According to the consortium, the site chosen has the optimal diurnal profile of strong wind at night and reliable sun during the day, and is also located near the coast for seawater intake and electrolysis.
New state-of-the-art equipment has been installed in the thermal stage of one of Europe’s largest Claus SRU units. Substoichiometric firing and a furnace designed with CFD calculations and a modern compact boiler system design based on detailed heat engineering and FEM calculations were key to the success of the retrofit. P. Foith of CS Combustion Solutions reports on the retrofit and how the novel combination of a CS low pressure swirl burner, additional mixing using a VectorWall™ and a new waste heat boiler design achieved the desired results.
Sulphur processing and handling equipment manufacturer IPCO has completed the commissioning of a groundbreaking new drum granulator in Italy that will serve as a global showcase for this patented system. C. Metheral of IPCO, describes the innovative approach and key features of the SG20 sulphur granulation system.
Ineos subsidiary Inovyn has announced the permanent closure of its ‘sulphur chemicals’ (mainly sulphuric acid) plant at its Runcorn site, and its withdrawal from the UK sulphur chemicals market. The company said in a statement that the decision follows a management review of the business in the light of recent events. Specifically, in October 2020, an unexpected interruption to the third-party power supply to the Runcorn site resulted in the plant being taken offline, and during restart, it was identified that a number of critical plant components had suffered significant damage. As a result, to ensure the safety and integrity of the plant it was taken back offline. Since then, in spite of significant effort and investment to rectify these issues, Inovyn says that it has become clear that it will not be possible to safely restart the plant for at least a further 18-24 months, and the company has decided to close the plant permanently.
With the sulphur content of crude oil and natural gas on the increase and with the ever-tightening sulphur content in fuels, refiners and gas processors will require additional sulphur recovery capacity. At the same time, environmental regulatory agencies of many countries continue to promulgate more stringent standards for sulphur emissions from oil, gas and chemical processing facilities. Rameshni & Associates Technology and Engineering discusses options for compliance with new regulations on emissions regarding IMO 2020 compliance and report on the results and evaluation of three case studies. Worley Comprimo reports on the revamp of a sulphur complex built in the late 1980s at a refinery in East Asia with the aim to increase the capacity, improve the availability and reliability and make the unit environmental compliant.
Reducing the carbon footprint in the synthesis of chemicals is a new global challenge as the world works towards providing sustainable products designed to minimise their environmental impacts throughout their whole lifecycle. This article looks at the role of blue technologies as part of a roadmap towards the decarbonisation of fuels and chemicals.
Gasification technology offers the promise of being able to convert the increasing volumes of municipal waste generated by society into useful chemical products. In spite of a patchy commercial record, interest in the process remains high.
