Alternative to amine-based gas purification: Reliable purification of special refinery gas streams

* PuraTreat R, the gas purification treatment for heavy-duty applications
* High-efficiency purification process


BASF now offers specialty amino acid salt formulations under the PuraTreat® R brand which are specially designed for the purification of highly aggressive refinery gas streams, and represent interesting alternatives to amine-based gas purification products. The new formulations are highly stable components which contribute significantly to the efficiency of the gas purification process and enhance the company’s extensive range of existing products.

PuraTreat R formulations reliably remove hydrogen sulfide (H2S) and – if necessary – carbon dioxide (CO2) from the gas mix, ensuring that the most stringent environmental protection requirements are easily met. PuraTreat R’s sequestration effect is so selective that the H2S removed from the gas is of a very high purity and can be processed without further treatment. Because of their physical and chemical properties, PuraTreat R formulations are more stable than amine-based solvents. As a result, the quantities of products requiring replenishment in the cyclical process are much lower by comparison. PuraTreat R formulations are suitable for use without additional investment as a replacement for amine-based gas purification products. Furthermore, the two purification technologies can be used in combination.

BASF gas purification products are successful throughout the world

BASF is a leading supplier of gas purification products and has extensive gas purification expertise. BASF’s Intermediates division markets a range of gas purification technologies, including aMDEA® - short for "activated methyl diethanolamine" – one of the leading technologies for the removal of acidic gases such as H2S and CO2. This BASF process, known as amine gas purification, has proved its worth for many years throughout the world in more than 220 gas purification facilities, mainly natural gas, ammonia and oxosynthesis gas plants. In addition to the customer proximity and service, BASF customers appreciate the company’s highly efficient and environmentally friendly technology because it is extremely flexible, avoids corrosion, consumes little energy, and requires little financial investment. It also ensures a high level of gas purity and a high yield of product gas in the presence of a low level of solvent loss.

BASF

The operating division Intermediates of the BASF Group develops, produces and markets the world’s largest range of intermediates. The most important of the division’s more than 600 products include amines, diols, polyalcohols, acids and specialties. Among other applications, intermediates are used as starting materials for coatings, plastics, pharmaceuticals, textile fibers, detergents and crop protectants. Innovative BASF intermediates help to improve the properties of the final product and the efficiency of production processes. The ISO 9001:2000-certified operating division Intermediates has access to plants at production sites in Europe, Asia, and the Americas. In 2005, this BASF operating division with 2,665 employees generated world sales of above 2 billion euros. For more information, go to www.basf.de/intermediates and www.gastreatment.com.
