How to use reverse demulsifier and avoid adverse effects?
How to use reverse demulsifier? Please read this article about precautions for the use of reverse demulsifier in refinery. Correcting the reverse demulsifier application will result in good performance. If the taboos in the use of reverse demulsifier are ignored, it will have various adverse effects on the environment:
1. Mixing incompatible agents with reverse demulsifier for oily wastewater.
If reverse demulsifier are mixed with incompatible agents for use, the following environmental impacts may occur:
1) Reduced treatment effect: It causes the oil and water in oily sewage to be unable to be effectively separated. Untreated sewage that fails to meet the standards will pollute surface water, such as rivers and lakes, after being discharged. Oil substances form an oil film on the water surface, hindering the gas exchange between the water body and the air and affecting the breathing and survival of aquatic organisms.
2) Generation of new pollutants if reverse demulsifier application is incorrect: The mixture of different agents may undergo chemical reactions to generate new harmful substances. If these substances enter the environment, they will cause pollution to the soil and water bodies and may even accumulate in organisms and be transferred through the food chain, causing greater harm to the ecosystem.
2. Improper Use Conditions about reverse demulsifier application
1) Unsuitable temperature and pH value when using reverse demulsifier in refinery:
Improper temperature: If reverse demulsifier are used at too high or too low temperatures, the demulsification effect is poor and oily sewage cannot be effectively treated. After discharge, oil substances will diffuse in the environment and pollute the soil and groundwater. Polluted soil will affect the growth of vegetation and the pollution of groundwater will affect the safety of drinking water sources and pose a threat to human health.
Unsuitable pH value: An unsuitable pH environment will make the ineffectiv of reverse demulsifier for oily wastewater treatment and the oil in the oily sewage cannot be separated, which will also cause water pollution. In addition, acidic or alkaline sewage with excessive strength after discharge may also change the pH value of the receiving water body and affect the living environment of aquatic organisms.
2) Excessive use:
Resource waste: Excessive use of reverse demulsifier not only increases economic costs but also causes waste of chemical resources. The production of reverse demulsifier requires the consumption of a large amount of energy and raw materials and excessive use will exacerbate the shortage of resources.
Secondary pollution: Excessive residues of reverse demulsifier may cause new pollution problems to the environment. For example, some reverse demulsifier in refinery may accumulate in water bodies and have toxic effects on aquatic organisms. At the same time, excessive reverse demulsifier in refinery may also affect the subsequent biological treatment process of the sewage treatment plant, reduce the activity of microorganisms, affect the sewage treatment effect and lead to more pollutants being discharged into the environment.
3. Improper Storage about reverse demulsifier application 1) Poor sealing: If reverse reverse demulsifier are not stored in a sealed manner, they may deteriorate after absorbing moisture, reducing the effectiveness of the reverse demulsifier for oily wastewater treatment. The deteriorated agent may not be able to play the normal demulsification role during use, resulting in ineffective separation of oil in the sewage and subsequent environmental pollution. 2) Close to fire sources and heat sources: Storage places close to fire sources and heat sources may cause fires or explosion accidents, not only causing serious harm to personnel and property but also releasing a large amount of harmful substances into the environment, such as toxic gases and smoke generated by combustion, causing pollution to the atmosphere, soil and water bodies.
