Individual reactor designs employ various methods to optimize dose delivery (e.g., higher lamp output versus lower lamp output and improved hydrodynamics through increased headloss). 2.4.2 UV Lamps UV light can be produced by the following variety of lamps: • Low-pressure (LP) mercury vapor lamps • Low-pressure high-output (LPHO) mercury ...

Jul 18, 2013 The variables for batch reactors include temperature, pressure, batch cycle time, the amount of reactants, and the feed addition strategy. Optimization variables such as batch cycle time and amount of reactant are continuous variables with fixed values for a certain batch reactor system depends mainly upon material and energy balance.

The concentration of a gas is related to its pressure by the ideal gas law: Concentration a n P mol b L V RT R gas constant 0.083 14 L bar mol K where n is the number of moles, V is volume (L), P is pressure (bar), and T is temperature (K). (a) The maximum pressure of ozone in the Antarctic stratosphere in Figure 1-1 is 19 mPa.

The reactor vessel is commonly about 7-8 meters in diameter and 10 meters high. Bed depths are typically*! meter while at rest, and 2 meters during operation. Variations in the depth affect both residence time and pressure drop, resulting in a compromised depth which optimizes residence time and excess air to ensure complete combustion [18].

The reactor was operated in batch mode by rotating the vial with a KPG stirrer (1200 rpm), which created a thin film (0.26 mm) of solvent-free reaction mixture. This reactor design was based on a rod mill apparatus that K nig et al. had previously introduced.
