Did you know there can be 5x more air pollution inside your house than outside of it? Indoor Air Quality (IAQ) refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. Understanding and controlling common pollutants indoors can help reduce risk of indoor health concerns. BASF offers the widest portfolio of adsorbent technologies for a broad spectrum of applications in industries such as refining, petrochemical, chemical, and gas processing. The BASF portfolio includes proprietary alumina, silica, alumino-silica gels and a broad line of base metal oxide guard bed materials, including the PuriStar family. At BASF, our Fluid Catalytic Cracking (FCC) catalyst and additive offerings together with our expert technical services build the right solution to create value within any unit’s constraints. The increasing demand for energy and resources is what drives us to develop more sustainable solutions, while addressing the need for energy efficiency and conservation.

Why BASF?

BASF Claus Catalysts and Tail Gas Treatment Solutions combine the strength of BASF, the global leader in catalysis, with the experience and expertise of our chemists and engineers.

If you’re looking for a manufacturer who knows how to make the right reaction happen, trust BASF. Our chemists and engineers have more than 40 years of Sulfur Recovery Unit (SRU) experience, providing expert plant designs while troubleshooting to increase lifetimes, improve performance, and reduce expenses. In addition, BASF’s state-of-the-art Claus Catalysts and Tail Gas Treatment Solutions are backed by the best technical support in the industry.

Overview of Sulfur Recovery

BASF offers superior catalysts and proven technologies for high sulfur recovery to achieve the desired performance and to meet environment requirements for sulfur emissions.

Claus Catalysts

We have the most extensive line of Claus Catalysts in the industry from one provider, offering titania catalyst and active and inert bed supports for the catalytic converters.

Tail Gas Treatment Solutions

These solutions increase sulfur recovery from Claus tail gas. They include catalysts and technologies that achieve the desired performance and to meet environmental requirements.

Overview of Sulfur Recovery

Sulfur recovery is an important process for natural gas processing plants and refineries. The raw feed streams often contain gases, such as H2S and CO2. H2S is a highly toxic gas and contributes to SO2 emissions. To comply with environmental regulations, the sulfur species are converted to elemental sulfur and water via sulfur recovery technologies such as Claus Sulfur Recovery Units and Tail Gas Treatment Units (Figure 1). BASF has high-quality products, proven technologies, and reliable services to meet your expectations and requirements.

Claus Catalysts

BASF has the most extensive line of Claus Catalysts in the industry from one provider. In addition to non-promoted and promoted activated alumina catalysts, we offer titania catalyst and active and inert bed supports for the catalytic converters. BASF Claus Catalysts provide the quality needed for maximizing the performance of the SRU.

Product portfolio:

Catalyst Type Product Name Characteristics
Activated Alumina DD-431 3/16" (4.8 mm) • High surface area with tailored pore size distribution for enhanced Claus activity
• Excellent Claus catalyst for common SRUs and sub-dew point reactors
Promoted Alumina DD-831 3/16" (4.8 mm) • Improved resistance to deactivation
