petrochemical sludge used in landfilling typically releases strong and unpleasant odors due to its high organic and chemical content. These odors can pose health risks and cause complaints from nearby communities.
Main Odor Sources:
Type of Gas Common Compounds Odor Characteristics
Sulfur Compounds Hydrogen sulfide (H₂S), mercaptans, Rotten egg, pungent smell dimethyl disulfide
Ammonia & Amines Ammonia (NH₃), trimethylamine Fishy, acrid smell
Volatile Organic Compounds Benzene, toluene, ketones, alcohols Irritating, toxic
(VOCs)
Organic Decomposition Decayed hydrocarbons, proteins Putrid, sour smell
Given the characteristics of petrochemical sludge landfills—strong odor, long-lasting emissions, and high moisture content—the following deodorant application methods are recommended:
Surface Spraying (Simple & Immediate)
Best for: Open landfill surfaces and exposed sludge
Use plant-based, neutralizing, or microbial deodorants
Dilute the deodorant (1:100 to 1:200 depending on product)
Spray evenly over sludge surfaces using misting equipment or hoses
Apply 1–2 times daily, especially after fresh sludge is added
💧Advantages: Easy to apply, immediate effect
💧Tip: Increase frequency in hot weather or windy conditions
