Consulting the technology of refining biodiesel from waste oil

I'll tell you when I'm waiting for the plane. Many people may want to know about the investment in biodiesel, because you haven't set the output, so my answer is not very specific! Let me give you an example. For example, your daily output of biodiesel is 1 tons.

His processes are pretreatment, esterification, transesterification, alcohol recovery, distillation and finished products. The final yield is 85% of biodiesel, 1% of plant clarification, and 5% of components.

Pretreatment

The main purpose of pretreatment is to remove water and impurities in waste oil, such as leftovers, leftovers and excess soil. It is very important to wait for a step, which will affect your subsequent processing. The investment here needs more than 8, yuan.

Esterification

Whether the oil can be turned into diesel depends on this step. The main purpose of esterification is to convert fatty acids in gutter oil into fatty acid methyl esters (biodiesel). For example, 1 acidic waste oil. Then this step is equivalent to 5% of the gutter oil becoming biodiesel. At the same time, 5% of it will enter the next step, and the investment in this step is about 25,

Transesterification

It is also an important step just like esterification, which mainly changes neutral oil into fatty acid methyl ester, that is, the other 5% of the gutter oil I mentioned above becomes fatty acid methyl ester. This step is also very important and the core part of biodiesel. So far, not many people have mastered the specific alkali addition amount. The equipment investment in this step is about 1,

Alcohol collection

Excessive methanol is needed in the process of esterification and transesterification, so this step is to recycle the methanol for purification. In this step, the cost of a methanol tower is estimated to be around 2,

Distillation

After all the above work is finished, your biodiesel crude ester will come out, which means 6% success. In this step, these crude methyl esters should be deodorized and distilled, and the two main equipments, the deodorizing tower and the distillation tower, also have supporting vacuum facilities. Heat conduction oil furnace, etc. It is estimated that it will cost about 5, yuan if you don't use a deodorizer tower, but the smell is slightly stronger. You can use flash evaporation instead. Then you can invest about 35, yuan.

There are public works to be mentioned, such as dirty oil pool, grease trap, circulating pool, chemical oil pool, transformer, steel structure of the factory building, pipes, valves, instruments, tank farm, power distribution pump, etc. It is estimated that these investments will be added by 8, yuan!

These are the real money spent. I have built many factories. These are all necessary. If anyone dares to say that he has tens of thousands or hundreds of thousands of biodiesel plants, I think it is an unreliable workshop! At present, the state has cracked down heavily on waste oil. If you want to build a factory, I hope you can go through the formalities first and be a good enterprise. If the profit of biodiesel continuous production is still considerable, you are afraid that production will stop. Finally, check it yourself. Good luck!
