Distillation of heavy aromatics in the production of hydrogen peroxide via the anthraquinone method
Thread Content
Should the distillation of heavy aromatics be carried out in a vacuum distillation still? The information I found states that it is in the working solution preparation kettle, and my equipment list does not include a vacuum distillation kettle either. Is there a process flow diagram for 100,000 tons per year at 27.5%? ? ?
It is distilled in a configuration tank – that’s correct. The configuration tank has three functions: preparing the working solution, adding alkali, and distilling aromatic hydrocarbons
