I would like to ask everyone: what does it mean to add alkali or not in the atmospheric and vacuum distillation process, and what is alkali?
What do you mean? It can’t be recycled used engine oil, right?
In the atmospheric and vacuum distillation process, not much alkali is added during the four-stage injection; usually, only water, corrosion inhibitors, and ammonia are injected. Does adding alkali refer to electrorefining? ?
If alkali is added to the constant pressure top section, ammonium salts will form and block the tube bundle of the heat exchanger in that section
Hello, are you adding alkali to the top of the tower now?
No, it says that no alkali is used in the tar distillation process; I don’t know what this alkali is
It should be sodium hydroxide, at various concentrations
