Issues regarding the quality specifications of white clay used for refinement
Thread Content
Our company currently uses clay with an activity level of around 180 and a moisture content of 11.5%. However, according to textbooks, the activity level of clay used for oil refining should be 220 or higher, with a moisture content of 6% to 8%. Since our oil is quite special, the amount of oil remaining on the clay after filtration is relatively high; therefore, we would like to try using clay with a higher activity level in order to use as little clay as possible. However, it seems that there are very few products on the market with an activity level greater than 220. I was wondering if any of you know anyone who works on such products; could you please introduce them?
