Lowering CO2 emissions with EARTH® technology

TechnipFMC’s EARTH ® technology, with its structured catalyst jointly developed by TechnipFMC and Clariant, has been proven to be a cost effective way to drastically improve productivity and energy efficiency of the steam reforming process, while reducing the CO 2 footprint per unit hydrogen and syngas product. The technology can be applied in projects to increase the capacity of ammonia and methanol plants and allows significant reduction of greenhouse gas emissions. S. Walspurger of Technip Benelux B.V. and S. Gebert of Clariant GmbH report on the EARTH ® technology and its applications.

Sulphur dust control through suppression

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.

Sulphur Industry News Roundup

US crude production dropped rapidly during April and May, but figures released by the Energy Information Administration (EIA) showed that this had plateaued and there have been some well reactivations and drawdowns from crude stocks. Total production curtailments in North America were more than 2.5 million bbl/d in May. ConocoPhillips Chairman and CEO Ryan Lance said in remarks to the media that a return to pre-outbreak production levels of 13 million bbl/d looked “pretty difficult”, although a recovery to 11 million bbl/d or possibly as high as 12 million bbl/d would be possible, depending upon OPEC moves. About one third of the company’s production was shut in as of the start of June – some 400,000 bbl/d. Lance argued that low cost shale oil resources still exist in the US, but there will be pressure on companies to reduce capital spending. The Covid19 outbreak has had a major impact in investment announcements, with a large number of project delays in the US due to uncertainty over future demand levels. Planned US exploration and production expenditure is down by 50% for the second half of 2020, while the rig count was down 60% on February.

Super selective hydrogen sulphide removal

The removal of hydrogen sulphide (H2 S) 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.

Caustic scrubbing of molten sulphur vent streams

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.
