Direct heating of solvents, especially low-boiling solvents such as ether nd carbon disulfide (bp a 30-60°), pose a risk of fire and should be avoided. Using a water bath will give more even heat distribution and give more control over the temperature.
needed. We are entitled to write only two material balances since two species are involved in the process; the third equation must therefore come from additional given information (the amount of benzene in the bottom stream.) The latter relation is. 72 kg B/h (Write 72 in place of on the chart) (kg B/h) 0.080[(0.45)(2000) kg/h]
Jan 15, 2019· What is boiler? It is an enclosed pressure vessel in which water is converted into steam by gaining heat from any source (coal, oil, gas etc). Boiler in thermal power plant accumulates the steam and build up a pressure to expend it in turbine and convert thermal energy to mechanical energy. The generator which is connected to turbine converts the mechanical energy into electric energy.
Hence, by controlling the water temperature externally, it is possible to control the outlet conditions of air, which then can be used for air conditioning purposes. In the air washer, the mean temperature of water droplets in contact with air decides the direction of heat and mass transfer.
