Abstract

PURPOSE: To provide a method for recovering chemicals from a pulp spent liquor by supplying the pulp spent liquor to the reacting zone of a reactor while also supplying an outer thermal energy independent of the burning, mutually independently controlling the temperature and an oxygen potential at the reacting zone, and binding the whole alkali and sulfur in a molten phase. CONSTITUTION: A pulp spent liquor is supplied to a reacting zone of a reactor while also supplying an outer thermal energy independent of the burning. The temperature and the oxygen potential at the reacting zone are mutually independently controlled, and if necessary, a carbon material and/or an oxygen- containing gas is supplied thereto. The substantially whole alkali and sulfur the separated from the vapor phase and bound to a molten phase taken out from a discharging opening connected to the reactor. An organic part of the spent liquor is simultaneously taken out in a shape of a gas.
