What is the difference between a batch refinery, semi-continuous refinery, and continuous refinery?

Date:2019-09-24/ FAQ/ Chat online/ Technical support

We all heard chemical refining and physical refining classified by refining methods. Likewise, palm oil refinery processing line can be classified to batch type palm oil refinery, semi-continuous palm oil refinery and full-continuous palm oil refinery according to different capacity range. Not only different capacity, but also their process flow & machines used, material consumption, oil loss and final cooking oil grade all different. Let’s see the details one by one.

Different types of palm oil refinery plant, different refining process flow:

Palm oil refining processing line contains four steps: degumming, deacidification (neutralization), decolorization and deodorization. In batch type palm oil refinery line, the four steps will process in four different tanks. In semi-continuous refinery line, the deodorization tank is changed to deodorization tower, removing odor more completely and further de-acid by steam to get fatty acid. For full-continuous, not only deodorization tank changed to tower, decolorization tank also changed to tower. And degumming step will together with decolorization step. de-acid part will be together with deodorization step in tower.

Different types of palm oil refinery plant, different technology consumption:

Palm oil refining technology more continuous and more automatic, the consumption will be less. Like steam consumption, in batch type refinery, deodorization part steam consumption is 750kg for 1ton per hour capacity; but in continuous refinery, the steam consumption is just 472kg for 1tph capacity. As for water consumption, batch type refining will consume 80kg per ton oil, but continuous refining line will consume 32kg per ton oil.

Different types of palm oil refinery plant, different oil loss;

During palm oil refining process, the main oil loss is from deacidification step. Batch type palm oil refining processing line use alkali and acid neutralized chemical way to remove acid. But continuous palm oil refining processing line use steam to extract fatty acid. In this way, the batch type oil loss will be higher than continuous refining way.

Different types of palm oil refinery plant, different land space;

Batch type palm oil refinery plant project require land space not need too high, but the length of the factory needs to be longer. Continuous refining line need high factory because of the height of the deodorization tower, the length not need much.
