<p>PURPOSE:To effectively utilize the latent heat as a heat source by introducing a generated gaseous component into absorption equipment via a device such as a turbine and bringing the gaseous component into contact with an absorptive high-b.p. liq. material. CONSTITUTION:A liq. to be vaporized is preheated in a preheater 7, introduced into the first evaporator of an evaporator 2, heated by an external heat source H through a heater 9 to vaporize a part of the component to be vaporized and then introduced into the second evaporator of the evaporator 2. The liq. introduced into the second evaporator is heated by a mixture of the high-temp. vapor returned from the absorbent regenerating part 4 of an absorptive condenser 1 and a noncondensable gas such as air to completely vaporize the component and then discharged to the outside of the system as a concd. liq. The vapor from the first and second evaporators of the evaporator 2 is introduced into the absorption part 3 of the condenser 1, brought into countercurrent contact with the absorbent and absorbed. Consequently, the vapor is completely absorbed, and energy is reduced.</p> |
