Whether to choose physical refining equipment or not depends on lots of factors, like FFA content, your crude oil quality, local environment requirement, etc. Last year, we Doing Company installed a 5tpd crude palm oil physical refinery plant project in Indonesia. That owner already had a 60tph palm oil mill plant and he wanted to refine the sludge oil and rotted palm fruit oil part.

Because of the high FFA content, this part crude palm oil quality is terrible. If use chemical refining equipment, the oil loss rate and NoOH solution addition will be very high. So the engineers of Henan Doing Company recommend to use physical refining technology, and can also reduce oil loss rate. This proposal is very suitable for owner’s requirement, therefore he decided to start a physical refining small scale edible oil refinery plant with 5tpd capacity. 

The other advantages of physical refining edible oil refinery plant
