Summary: | The invention relates to the technical field of temperature swing adsorption, in particular to a method for treating a faulty valve without stopping in a two-tower PTSA process, which comprises the following steps: after a one-tower adsorption A flow is finished, pre-pressure relief AD is performed on raw material gas, the pre-pressure relief AD is to close a raw material gas inlet valve and a product gas outlet valve of the tower, and when the two valves are closed and not closed, an alarm is given; the program immediately enters a pause state and prompts an operator to process, and the fault is paused after being removed; after the step of boosting R of the adsorption tower, pre-adsorption RA is carried out from the step before the end of the adsorption period of another adsorption tower to the pre-decompression AD, the pre-adsorption RA is a raw material air inlet valve and a product air outlet valve of the adsorption tower which is about to enter the adsorption A and is opened in advance, and when the val |
