As market situation and development needs, high concentration liquid NaOH became main product. This paper introduced that the defects of 70 000 t/a falling film evaporator system at early running, and the measures taken and programs. Comparison with traditional film evaporator system, which has advantages of simple flow path, distinct energy -saving effect, safety system and stable running, good operating environment etc.
