Abstract
The planning for the Salicylic Acid factory made from phenol using the Kolbe – Schmitt process is planned for a production capacity of 40,000 tons/year. Briefly, the process description of the Salicylic Acid factory made from phenol using the Kolbe - Schmitt process is as follows: The process of making salicylic acid includes three stages, namely the formation of sodium phenolate, sodium salicylate and salicylic acid. At the stage of sodium phenolate formation, the phenol is reacted with a sodium hydroxide solution using a stirred tank reactor where the two raw materials, namely sodium hydroxide and phenol, are obtained from the supplier. After sodium phenolate is formed, it will then flow to the bubble reactor to be reacted with carbon dioxide, thus forming sodium salicylate. Next, it flows to the decolorization tank. The decoloration process is carried out to remove the yellow color from sodium salicylate by adding activated carbon. After that, the solution is pumped to a filter press to separate the activated carbon cake from the sodium salicylate solution. The filtrate is collected in the filtrate tank, then flowed to the Precipitation Tank for acidification. 66% Sulfuric Acid. The salicylic acid formed will precipitate in the sodium sulfate solution. Then separate the salicylic acid crystals and sodium sulfate solution using a centrifuge. The pure salicylic acid crystals are then dried with a rotary dryer.
