Silica refining of palm oil
The use of silica (Trisyl) in combination with bleaching clay in palm oil refining has been investigated. The optimum conditions required for Trisyl and bleaching clay are 95–105°C for a period of 30–40 min. Improvements in color performance for palm oil products are noted with the addition of small quantities of Trisyl (0.06–0.24%) to ...
Optimal Metallurgical Flux Recipe for Primary Refining of …
In tests should be noted that if we have more oxides, further increase the composition of silica, but this will increase the viscosity. To reduce viscosity, increase Na2CO3, fluidizing, deoxidizing and desulfurizing. When the pot is so transparent, it is also indicative. I have worked with 50% borax, 16% Na2CO3 and 5% silica.
