<p>The present invention relates to a process for the preparation of a solution of sodium compounds formed together with a gas containing carbon monoxide, carbon dioxide and hydrogen gas, at partial combustion of cellulose spent liquors, the gas with its content of sodium compounds being brought into contact with at least one dissolving liquid in a device consisting of a vessel, containing a solving liquid and a vertically arranged downcoming tube (3), the upper part of which being connected to a gas generator (1) and the lower part of which debouching below the resting surface (14) of the solving liquid, whereby the gas and sodium compounds pass down through the downcoming tube (3), into which tube a dissolving liquid is added, and then pass between the downcoming tube (3) and an upcoming tube (6), the upper end of which debouches above the resting surface (14) of the dissolving liquid, and the lower end of which debouches therebelow, and which upcoming tube (6) wholly or partly surrounds the downcoming tube (3), whereby gas, sodium compounds and dissolving liquid being carried with the gas are brought into contact, whereby the sodium compounds are separated off and are dissolved in the dissolving liquid, which is drafted for the preparation of a digestion liquid.</p> |
