PROCESS FOR THE TREATMENT OF PHENOL AND TAR ACIDS CONTAINING OIL
The following invention relates to a process for recovering phenol and tar acids from different material feedstocks containing the said phenol and tar acids. The process comprises four main units including two cascading liquid-liquid extraction equipment, a solvent recovery unit and a purification section where pure phenol and pure isolated tar acids might be obtained by combined crystallizations from the melt and distillation. The primary solvent of the first liquid-liquid extraction unit is water. The secondary solvent in the second liquid-liquid extraction unit is a single mono- or polycyclic aromatic hydrocarbon, substituted or not, or a mixture thereof.
The following invention relates to a process for recovering phenol and tar acids (cresols, xylenols) from different material feedstocks containing the said phenol and tar acids. The process comprises three to four main units including two cascading liquid-liquid extraction equipment, a solvent recovery unit where a pure blend of phenols (phenol and tar acids) might be obtained, and a purification section where pure phenol and pure isolated tar acids might be obtained by combined crystallizations from the melt and distillation. The primary solvent of the first liquid-liquid extraction unit is water. The secondary solvent in the second liquid-liquid extraction unit is a single water immiscible mono- or polycyclic aromatic hydrocarbon, substituted or not, or a mixture thereof.
