Vaporizer
Thread Content
May I ask whether the vaporizer of the liquid oxygen system (1500 Nm3/h) is sufficient for the vaporizer of the liquid carbon dioxide system (1200 Nm3/h)? Could you explain the derivation process? Thank you!
It cannot be satisfied. With all other conditions being the same, carbon dioxide requires three times the heat exchange area as liquid oxygen; in other words, 3,600 cubic meters of liquid oxygen evaporator are needed to vaporize 1,200 cubic meters of carbon dioxide. A 1500-cubic-foot oxygen vaporizer can only vaporize 500 cubic feet of carbon dioxide.
I agree with view #2, that it cannot be satisfied, mainly because the values of their specific heats and heat of vaporization differ greatly.
