Sulfur Review: Topsoe
Published by Callum O'Reilly,

Hydrocarbon Engineering,
The April 2023 issue of Hydrocarbon Engineering includes our annual 'Sulfur Review', presenting a selection of sulfur services and technologies that are available and in use within the downstream oil and gas sector.
Below is Topsoe's contribution to this year's Review.
Topsoe has launched its new technology line, ‘Smarter Sulfur Solutions’, comprising the technologies listed below. While none of the technologies are brand new, they are now assembled under one headline.
WSA (Wet gas Sulfuric Acid), known and appreciated in a multitude of industries since the 1980s, turns sulfurous off-gasses into concentrated sulfuric acid of commercial quality with unsurpassed energy efficiency, SNOXTM flue gas desulfurisation, also removing NOX and particulates, without consuming limestone and without generating gypsum. The high energy efficiency of a SNOXTM unit helps reduce specific CO2 emissions from heaters, boilers and power plants by up to 10%, TopClaus®, jointly developed with Comprimo, is a combination of two proven technologies, Claus and WSA. TopClaus delivers effective sulfur removal at lower initial cost and lower operational costs than a Claus unit with conventional tail gas treatment. The Claus unit converts sulfur compounds in the feed streams to elemental sulfur with 95 – 97% efficiency. Residual sulfur is removed in the WSA unit, bringing the total sulfur recovery up to typically 99.9%, but higher recovery is possible when needed. The WSA unit produces sulfuric acid that is returned to the Claus unit to be reprocessed to elemental sulfur. TopClaus is well suited for both greenfield projects and revamps.
SmartSARTM for regeneration of spent sulfuric acid from alkylation and other operations without producing sour wastewater.
SweetPlusTM for cleaning of difficult fuel gasses to allow them to easily be used as fuel or even feed for hydrogen production, for example. SweetPlus combines a hydrogenation process with the WSA process to deliver sweet fuel gas, and the sulfur is removed in the form of concentrated sulfuric acid.
Topsoe is a world leader in catalysts and technologies that help the industry control sulfur levels in fuels and emissions. The company has licensed more than 165 units for removing sulfur from various gasses and waste streams. Topsoe’s hydroprocessing technologies and catalysts are widely used to remove sulfur, nitrogen, oxygen and metals from various oil fractions. The company is a leader in the production of ultra-low sulfur diesel and processing of renewable fuels.

The EIA reports that US distillate consumption so far this year is lower than usual because of warm winter weather, reduced manufacturing activity, and continued substitution of biofuels in place of petroleum distillate on the US West Coast (PADD 5).
