FIELD: process engineering.
SUBSTANCE: invention relates to fat-and-oil industry. Proposed process comprises the steps that follow. First, tall oil soap is separated from black alkali liquor in the vessel and/or centrifuge. Said tall oil soap thus separated is processed by acidation and/or decomposition. Then, additional separation is performed by, for example, the centrifuge. Fractions of black alkali liquor are be processed for extra extraction of tall oil soap before evaporation and feed to regeneration boiler.
EFFECT: higher efficiency of the process.
