By including the step of opening an existing air separation plant by using a liquid nitrogen discloses a method for increasing the liquid product. Liquefied nitrogen group nitrogen discharged from high pressure column (44) to the liquid-rich vapor stream 130. The nitrogen-rich liquid stream is returned 132 to the high pressure column. This increases the liquid nitrogen reflux to the high pressure column, and eventually increases the generation of a liquid oxygen column bottom contained a high-pressure column, so that the oxygen of the low pressure column (46) to increase the production of rich liquid (96). Oxygen-rich liquid is produced in increased be be obtained with a liquid oxygen product rate of increase, or a liquid oxygen product obtained in the first case, the plant is not designed to generate such a product. Further, as a result of the opening it may be created by the increased speed of liquid nitrogen, and argon product.
