In which stage do we separate the acid used for degumming in palm oil refining?

• After degumming

• After bleaching

• After neutralization

• During bleaching

Going back upstream, How do you think the harvesting of FFB could affect palm oil refining process in term of:

  - Energy saving point of view

  - Economic point of view

How do you think the bleaching earth is delivered to the bleaching column?

• Silo drop

• Menpower

• Blower/Fan

• Conveyer

What can we further “play” with the bleaching earth after separating them from the RB oil

• Deoiling for oil recovery

• Soil nutrient booster upon composting

• Soil conditioner for landfilling

• Energy by sending to furnace
