While the covid pandemic has kept refinery run rates down in 2020, new refinery sulphur capacity will nevertheless form the bulk of new additions to sulphur production over the next few years. But delays to projects on both the supply and demand sides could tip a fairly balanced market in either direction.
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.
Metal processing in Northeast Asia is the major source of sulphuric acid exports from the region, and the ramp up of Chinese copper smelter capacity is leading to increased acid availability.
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.
