Method and the device which cool the steam inside the stripping tower

摘要

It was arranged in the head of the stripping tower, it was constituted, as the indirect heat exchanger the stripping tower (2) inside the steam which rises being the method of cooling (3) the condenser where the coolant percolates making use of (1), at that time the coolant, the condenser (1) entering from underneath that inside, passing by the passage (8) of the verticality which is arranged inside the condenser, it regards the method of flowing to upward. With this invention, as for the coolant, as the condenser (1) before going inside, the hydrogen sulfide it is added, after absorbing heat, the condenser (1) it is above, it keeps coming out as overflow (6) through the open part (10) above the passage (8). In addition, the object of this invention is the stripping tower in order to execute this method (2).
