The Onondagas used iron pots to boil local brine water down to a dry salt. Hence, the first U.S. boiling water evaporators. The combination of water, salt and iron just doesn't mix well. Boiling water evaporators have not changed much over the last 350 years. Industrial wastewater evaporators are using boiling water technology and are still plagued with corrosion problems.
Many applications utilizing evaporators assume and plan for a less than one-year life.
Corrosion and meltdown are anticipated and accounted for. A new technology could change the history of evaporators. The process in which a liquid dissipates or emits vapor, fumes or invisible minute particles into the air. Amount of Energy required to raise a 1 lb. Organic compound, which readily dissipates into the air at room temperature, i.e., benzene, gasoline.
