摘要
Methods and systems for producing low methanol concentration acetone are provided. The method can include oxidizing and cleaving cumene to produce a crude acetone product. The crude acetone product can be neutralized in a neutralization unit to produce a neutralized crude acetone product. The neutralized crude acetone product can be fractionated in an acetone fractionation column to produce an acetone product and an acetone bottoms product. Methanol can be removed from the acetone bottoms product to produce a methanol-depleted product. The methanol-depleted product can be introduced to the neutralization unit, a dephenolation unit, or both.
