Abstract
The invention relates to removing contaminants from oil using solid sorbents that are comprised primarily of carbon and preferably of coke particles. The coke particles have an affinity for contaminants in oil and are sized to be filtered from oil without plugging. Most contaminants have such a small size that they tend to plug up filters. As the contaminants agglomerate onto the solid sorbent, the resulting particles form a filter cake on conventional filter materials in such a way as to allow the oil to pass on through without significant pressure drop or delay.
Claims19
A continuous process for removing contaminants from bio-sourced crude oil comprising:
- a) continuously adding a green coke containing solid sorbent to crude oil where the crude oil moves through a contained space and the solid sorbent is added to the contained space to move with the crude oil;
- b) mixing the crude oil and solid sorbent with a mixer;
- c) agglomerating/adsorbing contaminants from the crude oil to the solid sorbent;
- and
- d) continuously removing the solid sorbent with agglomerated/adsorbed contaminants from the contained space and from the crude oil.
