One Question per Day: Methanol Technology Discussion Edition 20180710
Thread Content
The reasons why the water solubility test for methanol products fails are as follows: 1. High levels of higher alcohols or paraffins in crude methanol； 2. The reflux ratios in the pressurized tower and the atmospheric pressure tower are too low, causing the heavier components to rise within the distillation tower and to be carried out with the product from the top of the tower ； 3. The amount of steam used for heating the reboiler is too high, resulting in mist entrainment or foaming at the top of the tower ； 4. Incomplete removal of pre-naphthenic hydrocarbons ； 5. The amount of fusel oil obtained from the side stream of the atmospheric tower is too low.
