Excerpt from An Electrical Method for the Determination of the Dew-Point of Flue GasesJ. F. The other hand, takes into consideration the effect of the presence of sulphuric acid vapor in the gases on the dew point. He states that, as the ¿ue gas temperature drops the sulphur trioxide gas begins to unite with the water vapor, forming sulphuric acid vapor, until at the boiling point of concentrated sulphuric acid (about 620 deg. F.) practically all of it is united. This acid vapor condenses in the same way as water vapor. On condensation, he writes, it first appears as an acid of per cent concentration, which becomes diluted by the absorption of water upon further cooling. Using the data of Thomas and Barkeri' for the partial pressures of sulphuric acid vapor over per cent sulphuric acid he calculates the temperature at which liquid will begin to form from the partial pressures of sulphuric acid in the gases as determined by analysis.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
