一道关于化工的题目,但是是英文的,
Steam at 300℃,10bar,is used in an evaporator to conentrate a 30kg/min solution at 30℃.The solution is concentrated such that it leaves the evaporator at a rate of 20kg/min.the evaporation takes place at 2 bar pressure.Determine the amount of steam that is required if the steam leaves the system at a saturated liquid at 10 bar.

答案

在300℃,10bar蒸汽应用中,一公斤conentrate蒸发30℃/分钟方案.解决的办法是集中这样,这使得蒸发器速度20kg /分钟.这个蒸发在2条的压力.确定数量的蒸汽,如果要离开这个系统的蒸汽饱和液体在10条.不是学这个的,只能给...
