Palm methyl esters have been found suitable as a green alternative to petroleum-based solvents. Palm methyl esters, in combination with surfactants, have good cleaning properties. The surfactants remove dirtfrom a soiledsurface while themethyl estershelptodissolve the polar deposits so that they remain suspended in the solution rather than being re-deposited on clean surfaces.

There is high demand for tocols (tocopherols and tocotrienols) as standard reference materials in scientific analyses as well as medical research. In addition, many other industries use them, such as cosmetics and nutraceuticals. The high demand for tocols has boosted its price. While tocopherols are readily available from both natural and synthetic sources, the supply … Read more

Filtration is used to dewater effluent, slurry and sludge. Sludge dewatering reduces its water content to be disposed of in landfills and reduces the volume of the residue for more stable and economical operation of the effluent plant. The major sludge dewatering processes include rotary drum vacuum filter, belt filter press and filter press. They … Read more

In the clarification of crude palm oil in the mill, the crude slurry is held for 4 to 7 hr in a vertical clarifier to allow the oil to rise above the sludge. Hot water is added and the temperature maintained at 95o C to reduce the viscosity of the slurry to enhance the rising … Read more
