The Description of The Oil Refining

Bookmark and Share

An oil refinery or petroleum refinery is an industrial process plant where crude oil is processed and refined into more useful petroleum products, such as gasoline, diesel fuel, asphalt base, heating oil, kerosene, and liquefied petroleum gas.[1][2] Oil refineries are typically large sprawling industrial complexes with extensive piping running throughout, carrying streams of fluids between large chemical processing units. In many ways, oil refineries use much of the technology of, and can be thought of as types of chemical plants. The crude oil feedstock has typically been processed by an oil production plant. There is usually an oil depot (tank farm) at or near an oil refinery for storage of bulk liquid products.

Oil Refining

Refining Process can remove phospholipids, FFA, pigment, off-flavor and other impurities. It includes the following sections: Degumming, De-acidifying, Bleaching, Deodorizing and Dewaxing. We can supply the equipment and technology to ensure that best finished oil is achieved with the lowest production


Physical Refining:
Physical refining means removing gum in oil during process of degumming in special method and removing FFA in process of deodorizing by steam. It has the following features:

    • Less oil loss and higher oil refining ratio;
    • No waste water in the process of production;
    • More FFA is distilled out;
    • More suitable for oil with high acid value and low gum impurity;

Chemical Refining:

Chemical refining means removing FFA in a chemical way ( Acid-base neutralization). Gum and soapfoot produced is separated by centrifuges. Chemical refining has following features:
1. Excellent adaptability and less requirement to oil quality;
2. The finished oil is consistent and stable;
3. Less bleaching earth is added into compared with physical refining. 

Advantages of our pre-treatment technology are as follows:
1. Complete continuous, Mechanical operation;
2. Computer automatic control system make all the pressure、Temperature、Liquid Level, etc controlled automatically;
3. Capacity and Quality can reach high level with the Centrifugal Separator;
4. Closed production line promise the high oil quality;
5. Energy saving with the heat multi-utilizing design;
6. High vacuum system produce high quality deodorized oil and energy saved;
