What is the typical reflux ratio used in hydrogenation fractionation towers?
For this question, it is generally best to provide a premise, or in other words, specify the processing capacity of the device, the type of processing technology used, the composition of the raw materials, etc., so as to ensure comparability.
The reflux ratio is generally controlled at 1-1.5, but this is not absolute. The backflow rate is greatly influenced by the backflow temperature and the feed temperature of the tower; however, a value of 1.5 or higher is usually sufficient to achieve the desired separation accuracy, as higher values lead to increased energy consumption
The reflux ratio of this unit is generally around 1.5, with a reflux volume of 16 tons. The delivery volume is between 9.5 and 11 tons
