The determination of the running cycle of the air separation plant is mainly based on the gradual accumulation of trace carbon dioxide after it is brought into the air separation tower during the design, until the time interval when it can not continue to run because of blocking. Under normal circumstances, the continuous running time of all low pressure oxygen generator should be more than one year, and the continuous running time of new molecular sieve adsorption process can be more than two years. However, in actual operation, the situation is much more complicated than the design. The main factors affecting the running cycle include the continuous working ability of the oxygen generator equipment and the running machine, the quality of heating and blowing before starting, the level of operation during the starting stage and normal operation, the size of the air load, etc. Most of the reasons that cause the oxygen generator to be shut down and overhauled before the specified peri...
