摘要： PROBLEM TO BE SOLVED: To provide a technique capable of extracting a product gas until an air separation device comes into a normal operation after restarting the operation of the air separation device. SOLUTION: This air separation device is provided with: a high-pressure distillation tower and a low-pressure distillation tower for separating material air into liquid oxygen and liquid nitrogen; a liquid storage tank for storing the separated liquid oxygen or liquid nitrogen; and a heat exchanger for evaporating and converting the liquid oxygen and/or the liquid nitrogen into a product gas by using compressed material air as a heat source. This air separation device is characterized in that a liquid extraction amount regulation valve is arranged in a line connecting the distillation tower to the liquid storage tank, and the device is provided with a pressing means for adjusting pressure in the liquid storage tank independently of the distillation tower when the liquid extraction amount regulation valve is closed.
