Removing Odour from Bitumen & Asphalt production using Anotec PRO5L

Chemical deodorisers and long-chain oils are both effective at minimising or eliminating odours in bitumen manufacturing through different mechanisms.


Chemical Deodorisers: Chemical deodorisers are typically formulated with active ingredients that are designed to neutralize or bind to odour-causing compounds, reducing the concentration of these compounds and thus reducing the intensity of the odour. This is typically achieved through chemical reactions between the active ingredients in the deodorizer and the odour-causing compounds, resulting in the formation of new, less odorous compounds. Chemical deodorizers are typically added to the exhaust stream at a specific point in the manufacturing process, where they can react with and neutralize the odour-causing compounds.

Long-Chain Oils: Long-chain oils are highly effective at adsorbing odour-causing compounds in the exhaust stream. This is because the long hydrocarbon chains in the oils are able to interact with the odour-causing compounds at a molecular level, resulting in the odour-causing compounds being trapped within the oil. This effectively reduces the concentration of odour-causing compounds in the exhaust stream, reducing the intensity of the odour.

The molecular mechanism underlying this process is based on van der Waals forces. These forces result from the attraction between the temporary dipoles that are present in all molecules. The long hydrocarbon chains in the long-chain oils contain a large number of temporary dipoles, which can interact with the temporary dipoles in the odour-causing compounds, resulting in the odour-causing compounds being trapped within the blend.

Anotec's specialized solution, PRO5L MOD, combines the benefits of both chemical deodorisers and long-chain oils. The proprietary blend of long-chained oils and formulated deodorisers work together to effectively adsorb and neutralise odour-causing compounds in the exhaust stream, reducing the concentration of these compounds and thus reducing the intensity of the odour. This provides a highly effective and safe solution for bitumen manufacturers who are looking to minimise the impact of odors on their surrounding environment and workers.

In conclusion, chemical deodorisers and long-chain oils are both effective at minimizing or eliminating odours in bitumen manufacturing, and Anotec's PRO5L MOD product offers a proprietary blend of these two technologies to provide a highly effective and safe solution. By combining the mechanisms of neutralisation and adsorption at a molecular level, PRO5L MOD effectively reduces the concentration of odour-causing compounds in the exhaust stream, providing a clean and odour-free environment for bitumen manufacturers and their surrounding communities.
