ABSTRACT:
Elevated temperature process for deoiling spent crystalline clay from the refining of glyceride esters ("oils") wherein a primary dispersion of such spent clay and aqueous alkali are mixed under pH conditions effective for removing a substantial amount of oily phase from such clay in the form of glyceride esters, thus-treated clay is separated and redispersed with additional aqueous alkali under pH conditions effective for saponifying at least a substantial fraction of the remaining glyceride esters present, then the treated clay is separated from the redispersion.
