ASPEN, enthalpy value, specific heat
Thread Content
1. What is the reference state for enthalpy in ASPEN? That is, under what conditions is the enthalpy value 0? 2. How to use ASPEN to find the specific heat and vaporization heat of a substance?
1. What is the reference state for enthalpy values in ASPEN? That is, under what conditions is the enthalpy value 0? Answer: I’m not sure about this, but personally I think it is under standard conditions. 2. How to use ASPEN to find the specific heat and vaporization heat of a substance? Answer: Create a new property set, add DHVL (heat of vaporization) and CP (specific heat capacity); by including the newly created properties in the report, the results can be viewed
Oh, thank you to the person above. By the way, how did you learn ASPEN?
You’re too kind, OP! I’m just a beginner; I find it difficult to learn Aspen as well. Without the guidance of a professional teacher and without the means to attend training courses, I can only keep going through the materials I have at hand. Fortunately, there are many kind friends on Haichuan, and it’s very helpful to communicate with them and learn from each other – it’s beneficial for personal growth. I also wish for Haichuan to continue to thrive, and hope that Aspen can be made more widely available in China sooner~~
If we’re just looking at these simple numbers, I think it’s more convenient to use CHEMCAD. Of course, CHEMCAD’s accuracy isn’t as high as that of ASPEN, but it’s still usable; it’s not any worse than what you can get by consulting manuals.
I hope experts can provide more detailed methods for finding material properties, which would be useful to many people
It seems that the information on the second floor isn’t very specific. I’ve also been trying to find the vaporization heat of hexene, but I haven’t been able to locate it; it may be necessary to calculate it. Therefore, I hope that the information on the second floor can explain the methods for finding the vaporization heat in more detail. Thank you!
