API Separator Package<\/strong><\/h2>\n

Product Introduction<\/strong><\/h3>\n

Our many years of experience in the design, fabrication, and separation of hydrocarbon\u2013water mixtures in accordance with international standards
\nhave enabled us to continuously improve our designs and deliver
\nsystems with higher performance levels and purer separation results.<\/p>\n

One of the main causes of system component failure in separators is the inability to remove thick and sticky sludge.
\nTherefore, selecting the right materials and using engineered equipment helps reduce maintenance requirements, increase lifespan, and lower operator dependency.<\/p>\n

Over the years, we have gained a comprehensive understanding of the applications, process requirements, and operational conditions of API separators.
\nThis experience, combined with our commitment to customer satisfaction, has resulted in smooth project execution, safe operation, and long-term reliable system performance.<\/p>\n

Nature of Industrial Water Contaminants and the Role of API<\/strong><\/h3>\n

Oils or hydrocarbons are among the main pollutants of industrial wastewater, especially in refineries and petrochemical plants.
\nThese oils exist in water in the following forms:<\/p>\n

    \n
  • Free oil:<\/strong> Large droplets that can be separated by gravity.<\/li>\n
  • Emulsified oil (1\u201310 microns):<\/strong> Requires flotation methods such as DAF<\/strong>.<\/li>\n
  • Dissolved oil:<\/strong> Removable only by biological or chemical<\/strong> treatment methods.<\/li>\n<\/ul>\n

    Free oils float on the water surface due to density difference and can be removed using gravity separation.
    \nEmulsified oils, due to their extremely small size, do not float easily and require DAF for removal.
    \nDissolved oils require advanced chemical or biological treatment processes.<\/p>\n

    The Role of API Separator in Wastewater Treatment<\/strong><\/h3>\n

    The API separator is typically the first and most important step in refinery wastewater treatment.
    \nIts primary function is to remove the bulk of free oils and suspended solids before the wastewater enters advanced treatment stages.<\/p>\n

    The API consists of a shallow rectangular basin that provides sufficient retention time for oil to float to the surface.
    \nThe calm flow helps improve gravitational separation.
    \nOil and grease droplets rise to the surface and are collected by a surface skimmer.
    \nAt the bottom, settling particles such as sludge and heavy debris are collected by a sludge scraper.<\/p>\n

    API can remove free oil, non-emulsified fats, and large suspended solids such as bolts, plastics, metal pieces, etc.
    \nHowever, it has limited ability to remove stable emulsified oil and contaminants such as COD, BOD, and dissolved organic matter.<\/p>\n

    Key Design Factors for API Systems<\/strong><\/h3>\n
      \n
    1. Flow velocity and hydraulic conditions<\/li>\n
    2. Oil density<\/li>\n
    3. Quantity and quality of suspended solids<\/li>\n
    4. Required separation efficiency<\/li>\n
    5. Oil concentration in water<\/li>\n
    6. Existing equipment and site conditions<\/li>\n
    7. Level of emulsified oil<\/li>\n
    8. Oil disposal or recovery method<\/li>\n
    9. Retention time and basin depth<\/li>\n<\/ol>\n

      It should be noted that API separators are not suitable for removing stable emulsified oils and have limited performance in removing dissolved contaminants.<\/p>\n
