(a)
Interpretation:
The principle behind the removal of pollutants from soil vapor extraction is to be determined.
Concept introduction:
When a liquid is vaporized it changes into the gaseous phase and when a gas condenses it converts to the liquid phase. The phase changes can be expressed as follows:
Vapor pressure is the pressure exerted by the vapors when the liquid and vapor phase are in the equilibrium with each other.
(b)
Interpretation:
The reason for the increase in the speed when heating is combined with SVE process is to be determined.
Concept introduction:
When a liquid is vaporized it changes into the gaseous phase and when a gas condenses it converts to the liquid phase. The phase changes can be expressed as follows:
Vapor pressure is the pressure exerted by the vapors when the liquid and vapor phase are in the equilibrium with each other. The volatility of a liquid is the ease with which a liquid can be vaporized. More volatile compounds vaporize at a higher temperature and less volatile compounds vaporize at a lower temperature.
