Calculation of energy consumption in refining units
Thread Content
How is the energy consumption calculated for units such as catalysis, atmospheric and vacuum distillation, coking, hydrocracking of gasoline and diesel, hydrogen production plants, gas separation, and MTBE? ? ? ? Also, what is the density of the low-pressure gas and the hydrogen production off-gas (desorption gas)? ? ? I need experts’ advice! ! ! !
The GB/T 2589-2008 standard is a bit old, but all the relevant formulas are included in it. To calculate density, you need to use the given components; you can find the necessary calculation methods by searching on Baidu
For exhaust gases with low levels, laboratory analysis and data processing are required; thereafter, an overall calculation is made based on the concentration of each component. Generally, there are reference values, and the deviations are not significant.
Dear, could you please tell us the values of the density of the hydrogen production off-gas (desorption gas) and the light fraction gas as far as you know? I’ll use it as a reference. . . Thank you! ! !
