Dear everyone, I want to calculate the mass percentage of sulfur in liquid hydrocarbons. **The quality specification for liquefied gas is 343 mg/m3. I’m not sure whether to use the values for gaseous or liquid states. If the density of liquefied gas is taken as 0.6 and its molecular weight as 50, then calculated on a liquid basis: 343/600 = 0.57 ppm. When calculated as an ideal gas: 343/(1000/22.4*50*10^-3) = 153 ppm. It’s not clear which value is correct
The principle is actually the same as that of temperature and pressure compensation; it can be converted to standard operating conditions when in use!
The results calculated based on gas are more reliable
