How is the hydrogen consumption in the hydrogenation reaction calculated? ?
Thread Content
I’m facing a problem now; I need to calculate the amount of hydrogen consumed in the hydrogenation reaction. Don’t know how to calculate it? Could that person help me out? I know the daily hydrogen consumption is 2.6 tons; what other parameters are needed? Please help Mang
Calculate the material balance: hydrogen consumed + hydrogen released
First, the composition of the raw materials is analyzed, along with the form, distribution, and content of sulfur and nitrogen in the oil; these constitute the basic data. In raw materials, those that can significantly consume hydrogen are unsaturated hydrocarbons, sulfides, nitrides, and oxides (these are either absent or negligible in oils that generally require hydrogenation). Unsaturated hydrocarbons are generally composed mainly of olefins; without high pressure and catalysts with high hydrogenation activity, simple aromatics will not be hydrogenated. These basic data can include: bromine value, diene value, sulfur content, nitrogen content, and acid value. These values are used to calculate the hydrogen consumption; empirical formulas for such calculations are usually provided in books on hydrogenation processes or in process packages.
Reactions are divided into main reactions and side reactions; calculations can be done directly using the reaction equations
What I need to calculate now is the hydrogen consumption of the actual reaction. I have a high-pressure hydrogenation isomerization reaction here. The total hydrogen consumption per hour by the unit is 111 kg/h. The processing capacity of the unit is 27 t/h. This hydrogen consumption includes hydrogen used in reactions, hydrogen emitted as waste gas, hydrogen released from low-pressure gases, and hydrogen lost due to system leaks. Because there is no flow rate indicator for hydrogen consumption in the emissions. So how do you calculate the hydrogen consumed in the reaction? ? I know the aromatic content in the raw material is 3%, S: 13 ppm, N: 2 ppm. Could someone help calculate it?

It is necessary to know the amount of substance and molar mass of the hydrogenation feedstock, as well as the remaining amount of reactants after hydrogenation; this allows for the calculation of the amount of hydrogen used. First, determine the molar quantity, and then use the gas law to calculate the mass. I hope this is helpful
