WebOct 24, 2024 · 1 Partial reboiler is related to that fact that most times, there is material left in the bottom of the column. This can be because you need to maintain a level of liquid because the bottom take off is a purified stream you want (as product or waste treatment input) or there is not enough area to maintain the proper amount of boil up. WebCharge the heat medium to the amine reboiler. 7.4.2.2 The amine system • Add the amine solution and start circulation. • Charge the heat medium gradually to the reboiler, taking caution of the thermal stress. • Start the lean/rich exchanger and the lean amine cooler and regenerator condenser. •

You can have 100% vaporization if you want, but it would mean no bottom liquid from the column. Kettle reboiler returns only vapor to column, excess liquid is extracted as bottom product.
WebKettle or gravity-fed reboilers There are dozens of other types of reboilers, but these four represent the majority of applications. Regardless of the type of reboiler used, the following statement is correct: Almost as many towers flood because of reboiler problems as because of tray problems. The most critical element of reboiler design is the selection of the proper type of reboiler for a specific service. Most reboilers are of the shell and tube heat exchanger type and normally steam is used as the heat source in such reboilers. However, other heat transfer fluids like hot oil or Dowtherm (TM) may be used. Fuel-fired furnaces may also be used as reboilers in some cases.
