preevaporator

Corrosion Cause analysis of pre-distillator in urea plant and countermeasures;

尿素系统预蒸馏塔的腐蚀分析及对策

A new technology of liquid fuel combustion, the so called pre evaporation combustion technique, is presented, which allows the "gasified" combustion of liquid fuel through the separation of its evaporation and combustion process.

介绍一种燃烧液体燃料的新技术—预蒸发燃烧技术 ,通过分离液体燃料的蒸发过程和燃烧过程 ,实现液体燃料的“气体化”燃烧。

The water flux increases along with the prolonging of pre-evaporation and the increasing of coagulation bath temperature.

水通量随着预蒸发时间的延长、凝固浴温度的上升而上升;孔隙率随着凝固浴温度的上升而上升,而与预蒸发时间的长短没有关系;对牛血清白蛋白的截留率随着凝固浴温度的上升而下降,随着预蒸发时间的延长先略有下降然后上升。
