The membrane can be used for concentrating ethanol from dilute ethanol-water mixture through pervaporation process owing to its alcohol-permselective properties.
This research discovered that soil pondage of level terrace were less than fallow sloping filed because of crops’ absorbing and using, and evaporation.
It focuses on the flash tank devolatilizer which is most widely employed in industry.This type of devolatilizer is simple structure,low cost and high productivity.
Uranium isotope abundance ratio has been measured by total sample evaporation and signal integration,and a thermal surface ionization mass sepctrometry equipped with multicollector has been used.
According to the ZBO storage methods of other cyogenic liquids, an idea of centralized recondensation of liquid hydrogen in large containers by using cryocoolers was suggested.
In order to increase water speed and turbulivity in ice-storage tank of direct evaporating and external melting ice-on-coil system, cambered baffles are installed in the ice-storage tank.
Passive and Hybrid Downdraught Cooling, which rely on natural cooling processes based on water evaporation and solar power, are now technically viable in many parts of the world.
When the vapor emanated from the skin surface can not easily permeate to the air, it will form a high humidity region between the skin and the fabric which makes people feel mugginess and discomfort.
