During the shutdown for maintenance in the hydrogen production plant, external tube train vehicles are used to supply hydrogen – how should the hydrogen consumption be calculated? For example: When a tube bundle truck arrives and is put into use, the instruments on it show a temperature of 30 degrees and a pressure of 18.0 Mpa; the volume of the tube bundle truck is 23 cubic meters ； At the end of use: temperature 32 degrees, pressure: 2.0 Mpa, volume of the tube train vehicle 23 cubic meters (unchanged) ； How do you calculate exactly how many cubic meters of hydrogen were used? Please provide the calculation process, thank you
This is how we calculated it: (180kg – 20kg) x 23m3 = 3680m3
The temperature is generally not taken into account; 1.0 MPA is approximately equivalent to 10 kilograms. (180-20)*23=3680.
