Crude Phenol Purification Technology Proprietary Technology and Plants Technology Introduction: Phenols have a variety of compounds, with the most important ones incl. phenol(carbonic acid), and cresol(o-cresol, m-cresol and p-cresol); among them, phenol is mainly used as the feedstock for di-phenol A production and phenol formaldehyde production; o-cresol is widely used in the synthesis of resin, pesticide, medicine, perfume, dyes, antioxidant and etc.; m-cresol is an very important feedstock for the production of Vitamin E; p-cresol is widely applied in the synthesis of BHT, the most employed antioxidant in the world. SL TEC offers the technology of crude phenol purification with the phenol either from coking phenol, or gasified phenol or alkylation liquid. Based on the facts that the boiling points of the main product and the by-products are quite diffe*ain condition and the boiling points will decrease with the reducing of the pressure, SL TEC's technology lowers the separation temperature by reducing the system system, distill, separate and purify to get high purity phenol separately. Technical Features: In the traditional crude phenol purification process, usually water removing, residue removing, phenol purification units in batch are involved to separate and purify phenol, cresol and other products. In this batch production, the intermediate distillate between adjacent components requires repeated rectification to increase the yield, thereby the productivity is low, the energy consumption is low and only suitable for small production capacity; in addition, as the phenol products have certain heat sensitivity, the repeated heating not only decreases the total yield but also results in the unstable product quality. While SL TEC provides a technology based on the achievements by cooperation with Tianjin University. It is based on continuous vacuum
