In the gas distribution industry, the phenomenon of odor fade presents a unique challenge. Characterized by the loss of odorant compounds in gas pipelines due to chemical decomposition reactions and physical removal processes, odor fade can compromise safety measures. This article explores the factors contributing to odor fade and how Burgess Pipeline Services offers solutions to this issue.
Understanding Odor Fade
Odor fade predominantly occurs in specific segments of the pipeline, such as newly installed sections, low-flow areas, or recently cleaned/hydrostatically tested pipes. It results from a combination of chemical processes and physical phenomena, including chemical reactions, adsorption, absorption, and desorption.
Chemical Reactions and Odor Fade
Mercaptans, commonly used odorants, undergo chemical oxidation under certain pipeline conditions, forming less odorous disulfides. The rates of oxidation vary among different odorants, with lower molecular weight mercaptans being more susceptible.
Adsorption and Absorption in Odor Fade
Adsorption is the physical attraction of gaseous molecules to surfaces, driven by weak forces. Odorant molecules may be removed from the gas stream and adhere to pipeline walls. Absorption involves the filling of pores in solids or dissolution into liquids. This process is distinct from adsorption and may occur in pipelines, especially under static or low-flow conditions.
The Role of Pipeline Materials in Odor Fade
The materials used in pipeline construction, primarily steel and plastic, interact differently with odorants, impacting odorant loss. Factors such as internal surface characteristics, rust presence, and operational conditions contribute to the overall understanding of odor fade.
