Sulfur removal | Treatment of sulfurous off-gasses

2000x650 Application Treatment of sulfurous off-gasses

Protect your profit with cost-effective off-gas treatment solutions

Maximizing sulfur recovery from off-gasses is vital for today’s oil and gas industry. Regulations are tightening, and operators are forced to constantly optimize the efficiency of their sulfur management units.
 
Off-gas treatment includes several gas types, complex legal requirements, and diverse business goals and operational needs. Without the right strategy and technology, the treatment process can quickly become a heavy economic burden on your operation.
 
Topsoe’s solutions and services give the know-how and technology needed to strike a balance between the economic, environmental, and operational requirements that operators face when dealing with sulfurous off-gasses. Our well-proven and innovative solutions help minimize the costs associated with off-gasses and can even create new commercial opportunities that are aimed at reducing environmental impact.

Convert sulfur, purify fuel gasses or desulfurize flue gas

Our WSA technology converts the sulfur compounds in off-gases to valuable sulfuric acid with the best-in-class energy economy. You can also turn sulfur compounds into elemental sulfur with our advanced TopClaus® technology. This innovative solution delivers unprecedented recovery rates and energy economy.
 
We can help you purify problematic fuel gasses and lower sulfur content to meet legislation with our innovative SweetPlus™ technology. Our SNOX™ technology can also help desulfurize flue gas (FGD) and remove NOx and particulates, without limestone application or gypsum production.
 
No matter your goals regarding off-gas treatment, we can help you with know-how, technology, and services. All our solutions and services are designed for a cost-effective lifecycle to help you protect your profit.
