Smarter Sulfur Solutions solve your industry's challenges

Oil refining and natural gas

Convert sour off-gases into valuable sulfuric acid or elemental sulfur
Regenerate alkylation spent acid via a waste-free, energy efficient process
remove harmful pollutants from flue gas without consuming limestone or generation waste materials

Pulp and viscose production

Recover sulfur from sulfurous off-gases such as CNCG, lean gases, and H2S-rich gases, as sulfuric acid for reuse within the site or plant
Increase sulfuric acid production by adding molten sulfur to meet the plant's consumption
Minimize chemical import to the plant through efficient recovery or recycling

Metallurgy

Convert SO2 off-gases into sulfuric acid for reuse or a new revenue stream
Gain a reliable solution for SO2 emissions control to meet requirements and reduce the risk of environmental damage
Treat fluctuating SO2 off-gases at high and low SO2 concentrations reliably

Carbon black

Minimize SO2 emissions while producing sulfuric acid as a new revenue stream
Handle Particulate matter emissions in a reliable unit for reduced environmental impact
Increase plant efficiency through improved heat recovery

What we deliver

Applications within this area

Sulfuric acid production

Sulfuric acid production - sulfur emissions standards are constantly tightening, forcing industrial, chemical, refining, and metallurgical operations to find ways to comply with legislation and maintain profitability.

Spent acid regeneration

Turn your challenges into opportunities today by partnering with Topsoe and taking advantage of our know-how, technology, and services for spent acid regeneration.

Sulfur recovery

Sulfur recovery solutions are a vital part of the picture when it comes to making the most of wasted sulfur compounds.

Flue gas treatment

Topsoe’s flue gas treatment solution, SNOX™, helps you overcome FGD’s common challenges by recovering sulfur as commercial-grade sulfuric acid, instead of as gypsum.

Treatment of sulfurous off-gasses

Treatment of sulfurous off-gasses - maximizing sulfur recovery from off-gasses is vital for today’s oil and gas industry.
