Hydrogen-to-oil ratio in the hydrogenation unit
Thread Content
What measures are mainly used to adjust the hydrogen-to-oil ratio in hydroprocessing?
It mainly relies on increasing the amount of hydrogen or reducing the amount of oil; there is white foam in the circulating water, and the reason is unknown. https://bbs.hcbbs.com/thread-5669817-1-1.html (Source: Haichuan Chemical Industry Forum)
The hydrogen-to-oil ratio in hydroprocessing is primarily adjusted by modifying the flow rate of hydrogen and the flow rate of the feed oil. .
The hydrogen-to-oil ratio is generally a volume ratio, calculated as the amount of recycled hydrogen * its purity plus the amount of new hydrogen * its purity (this represents the hydrogen), divided by the processing volume/density (this represents the oil); this gives the volume hydrogen-to-oil ratio
It is necessary to increase the hydrogen volume or reduce the oil volume in order to improve the purity of the circulating hydrogen
