The vapor from a chlorine vaporizer will contain some liquid droplets. The vaporizer consists of a vertical, cylindrical vessel with a submerged bundle for heating. A vapor rate of 2500 kg/h is required and the vaporizer will operate at 6 bara. Size the vessel to restrict the carryover of liquid droplets. The liquid hold-up time need not be considered, as the liquid level will be a function of the thermal design.
A plating waste with a flow of 50 L/min contains 274 mg/L of NaCN. Determine the amounts of chlorine as Ca(OCl)2 and NaOH required to: (a) Oxidize the cyanide to cyanide; and (b) Oxidize the cyanide to CO2 and H2O.
Combustion of Ethane: Stack Gas Molar Composition, Ethane is burned with 50% excess air. The percentage conversion of ethane is 90%. Of the ethane burned, 25% reacts to form CO and the balance reacts to form carbon dioxide
