Useful HYSYS Short Cut

Hi my friend, in this posting, I just want to remind you several useful short cuts in HYSYS. Actually, It’s a simple material of training course for beginner. But, in fact, some engineers have forgotten it, although they have used HYSYS long time ago.

HYSYS provides many short cut, you can check it there.It very helpfull. Try it.

Rigorous Method for Fire Case

In previous article, I have explained that relieving load for fire case can be calculated as heat input divided by latent heat of vaporization. (W = Q/Hv). The heat input have been discussed before, see fire case –heat input rate. The latent heat of vaporization is rather difficult to be determined. During fire, liquid in the vessel will be vaporized, but the amount of vapor formed is not fixed, because the liquid composition is change overtime. In this article, I will explain you step by step the rigorous method for fire case
