Abstract
Disclosed is a method for removing phenols from an underground gasification zone by injecting an alkaline material to convert at least a portion of the phenols to the corresponding salt and producing the solution of said salt. Thereafter, the salt can be converted to the free phenol or merely evaporated to dryness. In both of these cases, the phenol or salt can be incinerated.
