Abstract
PURPOSE: To contrive the energy economization of surrounding equipment of distilling column, by cooling and condensing overhead gas of distilling column and utilizing each cold and hot gas obtained by inducing uncondensed gas to heat separation apparatus, as cold heat source of cooling of each overhead gas and reheating heat source of circulating liquid of distilling column.
CONSTITUTION: Overhead gas discharged from the distilling column 2, is separated in condensed liquid and uncondensed gas at the gas-liquid separator 8 after the overhead gas is cooled and condensed at the condenser 7. Then, the uncondensed gas is induced to the heat separating apparatus 21 and is made cold gas by reducing pressure and bringing down temperature and on the one hand, residual gas in the apparatus 21 is made high temperature gas. Next, the above cold gas is induced to the cooler 22 and is used for cooling and condensing the overhead gas after cooling and condensing by the cooling condenser 7 moreover. On the one hand, the above high temperature ga is induced to the heater 23 and is used for reheating of the circularing liquid 4. As a result of it, increase or decrease of the equipment of the condenser 7 and quantity of cooling medium, is able to contrive and at the same time, that of the equipment of the reboiler 5 and quantity of heating medium, is able to contrive.
