Abstract
The invention discloses a process for deamination and degasification of filtrated stock generated during alkali making. The process is characterized by comprising the following steps of: continuously inputting the filtrated stock generated during alkali making and hydrochloric acid into an acid-proof open container in a reactive mixture ratio; and uniformly mixing until the pH value is equal to 5.8 to 6.5 to finish acidification, wherein free ammonia in the filtrated stock is transformed into fixed ammonium, and carbon dioxide gas is released at the same time. By adopting the process, special equipment is not required, the investment is low, and the investment of capital construction is only 1/100 of that of a physical distillation method; steam and other energy are not consumed, so that the use cost is reduced; and the reaction is finished instantly, so that the production efficiency is high, and the process is convenient to operate.
