Boiling Point of Ethanol @ 100 mmHg = 31.5°C. Heat Capacity of Ethanol @ 100 mmHg = 112.4 J/mol K. Heat Required to raise temperature from 25 to 31.5°C = 0.73 kJ. At first glance it seems that the cost of boiling ethanol is reduced (in this example by 800%) when using a vacuum pump.

WebAug 1, 1996 · The boiling temperature of seawater can be lowered to as low as 400°C by the creation of a vacuum. Using waste heat from a steam turbine, a pilot study was conducted in the laboratory to investigate the feasibility of using a vacuum desalination process for water supply. ... 131-135 Vacuum desalination for water purification … WebDec 26, 2024 · When the liquid and vapor exist at the same place at a given temperature in a closed system, they have a known pressure. We call this the pressure-temperature (P-T) relationship. This relationship will exist as long as you have at least a droplet of liquid in a closed system. However, the refrigerant must be at its saturation point. react header code
