Calculation of the material balance regarding the normal hydrogen production volume of the device
Thread Content
My unit is capable of carrying out 2 million tons per year of wax oil hydrocracking. The inlet volume of the recycle hydrogen compressor is 270,000 cubic meters; the outlet volume of the fresh hydrogen compressor is 50,000 cubic meters. The hydrogen consumption is 45,000 cubic meters. Hydrogen mixing is done after the furnace, and after passing through the heater, the volume becomes 180,000 cubic meters. After heat exchange in the heat exchanger, this volume rises to 200,000 cubic meters. The amount of hydrogen supplied is 20,000 cubic meters. Yet the figures still don’t add up: 27 + 5 – 20 – 4.5 – 2 = 55,000 cubic meters. Is the formula correct? Where do these 55,000 cubic meters go? The counter-rotation feature isn’t activated, nor is the cold hydrogen system in use
The formula does not hold; according to PV=RT, when the temperatures are different, the pressures are also different, so the volume is different as well. Temperature and pressure must both be taken into account.
Hello, the unit I’m referring to is standard liters per hour
I used to have the same idea, but once it’s been defined, is it still necessary to use this formula for calculations?
