BASF building production plant for specialty zeolites in Ludwigshafen
BASF SE (Ludwigshafen, Germany; www.basf.com) is investing in the construction of a production plant for specialty zeolites at its Ludwigshafen, Germany, headquarters site. The plant is expected to start up operations in the first quarter of 2014, significantly increasing BASF’s production capacity for specialty zeolites. [more]
Eco-efficiency methodology is a tool for sustainable chemical production
An ecological efficiency methodology developed by BASF SE (Ludwigshafen, Germany; www.basf.com) is a powerful tool for assessing the sustainability of chemical processes and operations. The company’s Eco-Efficiency analysis is a holistic method to life-cycle assessment that has been validated externally, says Peter Saling, a leader of BASF’s Sustainability Center. [more]
Development Speeds up In Catalysis
There might be as many categories of catalysts as there are chemical processing applications. And, no matter what the specialty or application, most catalyst producers are in a constant state of research and development in order to meet the demands of their chemical processing customers, as well as to develop innovative catalysts for new applications and growing market areas. Recent efforts of some of the top catalyst producers are improving…[more]
FROM OUR SPONSOR
Nitrous oxide, or laughing gas, is 310 times more effective than carbon dioxide (CO2) in trapping heat in the atmosphere. BASF offers state-of-the-art N2O decomposition and selective catalytic reduction (SCR) DeNOx technologies which reduce N2O and nitric oxides (NO and NO2). Both catalyst families, which were originally developed to reduce harmful impurities in nitric acid and adipic acid plants, have been utilized for emission removal in numerous industrial applications, including off-gases from various sources. They can be used either individually or in various combinations in relevant plant configurations.
BASF N2O decomposition technology utilizes a series of full, 100% active homogeneously extruded catalysts with a thermally stable spinell structure. The catalysts offer the highest temperature resistance and do not leach. They are available in various geometries and sizes, including extrudates, ring tablets, and honeycombs. An N2O efficiency of greater than 90% is possible. The choice of shape and size depends on operating conditions and the specifications that need to be met.
The BASF DeNOx system provided as a complete system together with our engineering partners is an end-of-pipe solution, which can either be installed before the expander or directly before the stack. The most advanced catalyst is O4-89 as an extrudate, but in some niche applications, especially at ambient pressure, the monolithic catalyst O4-82 can be used. BASF O4-89 has been successfully applied for the removal of NOx from tailgas derived from nitric acid plants, caprolactam units, gas turbines, refinery furnaces, waste incinerators, power plants, and diesel engines.
BASF’s flexible solutions for N2O decomposition include easy handling capability, compatibility with any Pt gauze, and minimal impact on quality. The SCR DeNOx whether used alone or in conjunction with the N2O system is an ideal solution for handling tailgas. Along with its wide range of operating window for temperatures and pressures, it achieves high NOx conversion in addition to low pressure drop and NH3 slip. Both technologies are backed by reliable warranties and outstanding support and service that are associated with BASF – The Chemical Company. At BASF, we create chemistry for a sustainable future.
