In the realm of oil derivatives, Treated Residual Aromatic Extract, or TRAE, is a remarkable substance that often flies under the radar.
TRAE is a specialized byproduct of the petroleum refining process. It is derived from the residues left after the initial distillation of crude oil. What sets TRAE apart is its treatment process, which involves removing impurities and undesirable components, leaving behind a high-quality aromatic extract.
