METHOD FOR PURIFYING STEAM

摘要

The invention provides a method for purifying steam that comprises one or more contaminants. In the method the contaminated steam is dispersed as bubbles in a water column, in which water column a flow of water is introduced below the location where the steam is dispersed as bubbles. Water is caused to flow upwards whereby complete condensation of the bubbles occurs. The heated water obtained flows upward and establishes a pressure drop in the water column as a result of which purified steam is generated. The purified steam so obtained is then separated from water that comprises the one or more contaminants. Subsequently, the contaminants are separated from the water, and purified steam and purified water are separately collected .
