The impact of methanol in crude oil on hydrorefining
It’s quite rare for the feedstock used in hydrogenation refining units to contain methanol; its boiling point is too low, so methanol should not be present in feed oils such as gasoline and diesel that require hydrogenation refining. If methanol is present in the feedstock, it will be hydrogenated to remove the hydroxyl group, resulting in hydrated methane. If the methanol content is too high, it will affect the purity of the circulating hydrogen; water will lead to a decrease in the mechanical strength of the catalyst and an increase in the pressure drop across the bed.
Thank you. Our equipment encountered such a problem; later, washing the crude oil with water resolved it, and the purity of the recycled hydrogen was over 70%
