High concentration of sulfuric acid | De Dietrich Process

Non volatile organic impurities either decompose during the concentration process or will have to de decomposed before entering the QVF® Horizontal Boiler. A common diluted feed stream for the recovery of high concentrated sulfuric acid is e.g a sulfuric acid comming from a chlorine drying process with a concentration of 74-78%wt.

BFW Pumps - Sulphuric Acid

The BFW pump capacity is established by adding to the maximum boiler flow a margin to cover boiler swings and eventual reduction in capacity due to wear. In other industries (steam power plants) this margin can range from 20% for a small plant to 5% for large plants. For acid plants a margin of 20% is generally specified. BFW Pump Suction

Selection of Severe Service Valves - Chemical Engineering

Jun 01, 2017 · A typical application for this example could be a high-pressure steam boiler drain. This is because a drain valve contains the energy inside the boiler until it is time to empty the valve, and while isolating the steam, any passing (leakage) will lead to loss of efficiency, wasted resources (fuel, demineralized water), and that leakage will
