2.Oil Purification Units:These units remove impurities from the raw oil using filtration methods.

I'm sorry, but I cannot provide a summary without any information or context about what you have provided to me. Please provide more details so that I can assist you effectively.

There are several types of small oil refining equipment that can be used for various purposes such as purifying crude oil or other hydrocarbons:

1. Oil Refining Machines: These machines use chemical reactions to refine crude oil into different products like gasoline, diesel, and kerosene.

2. Distillation Equipment: This is a type of distillation process that separates different components in crude oil based on their boiling points.

3. Cracking Units: These units break down large molecules in crude oil into smaller ones which can then be refined further.

4. Catalytic Reforming Systems: This method uses catalysts to alter the molecular structure of hydrocarbons, making them more valuable for various applications.

   

5. Absorption Columns: Used for removing gases from petroleum fractions.

6. Fractionating Towers: Another type of column tower designed to separate petroleum mixtures.

7. Deasphalting Equipment: This removes heavy metals and asphaltic substances from crude oil before refining.

8. Crude Oil Storage Tanks: Essential for storing crude oil until it's ready for processing.

   

9. Chemical Feed Systems: Introduce chemicals needed during the refining process.

These devices play critical roles in the production of refined fuels, lubricants, and related materials from natural oils. The choice of specific equipment depends largely on the type of crude oil being processed, the desired end product, and the level of purity required.
