The specification for a sieve plate column is given below. Make a preliminary mechanical design for the column. Your design should include:
A living plant contains approximately the same fraction of carbon- 14 as in atmospheric carbon dioxide. Assuming that the observed rate of decay of carbon-14 from a living plant is 13.6 counts per minute per gram of carbon
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 des..
Calculate the mass flow rate of distillate and bottom product per hour - the mass flow rate of liquid entering the reboiler and the vapour leaving the reboiler per hour.
One of the classical methods for the determination of the manganese content in steel is to convert all the manganese to the deeply colored permanganate ion and then to measure the absorption of light.
