Sulfur Trioxide and Oleum - Veolia North America

sulfuric acid. As you can see, sulfur and air are brought in and burned to make sulfur dioxide (SO 2). The SO 2 goes through a series of gas cooling and heat recovery operations, and then is run through a catalytic converter to make sulfur trioxide (SO 3). The sulfur trioxide is absorbed in sulfuric acid. Water is added to control the sulfuric

Sulfur recirculation for increased electricity production

Jan 01, 2014 · An SO 2-setpoint was maintained by controlling the sulfuric acid dosage to the boiler.. The corrosions rates decreased significantly for 16Mo3, Sanicro 28 and Inconel 625. • Sulfur recirculation allowed an increase from 450 to 525 °C at similar corrosion rates.. The raw gas and fly ash PCDD/F concentrations decreased by a quarter.

Corrosion Analysis of Air Pre-Heater Tubes of CFBC Boiler

in the exhaust gas. In the case of a boiler that burns heavy oil or coal, S in the fuel turns into sulphur oxide (SOX) and, if the inner surface temperature of a steel plate of the smoke duct is lowers than the dew point of sulphuric acid, sulphuric acid condenses into dew, and there occurs sulphuric acid dew corrosion.

Alkalinity and pH – Water Technology Report

Jul 26, 2016 · Alkalinity is easily measured by titration with a standard solution of N/50 sulfuric acid using two color indicator solutions: Phenolphthalein and Methyl Purple. Phenolphthalein changes color at pH 8.3 and Methyl purple at pH 4.3. The titration test is named P alkalinity and M alkalinity by reference to the indicators used for each titration.
