Claims

[Claims for Utility Model Registration] Two or more separation cylinders filled with a separation agent such as an adsorbent or an absorbent are connected in parallel between an inlet and an outlet, and each separation cylinder A mixed gas containing one or more gases to be separated is supplied to the separation cylinder at high pressure from the inlet, and the separated treated gas is discharged by adsorbing or absorbing the gas into the separation agent. A separation step of discharging from the outlet;
An evacuation process for discharging the gas in the separation cylinder to the outside to reduce the pressure in the separation cylinder, and a mechanism for squeezing a part of the treated gas from the other separation cylinder in the separation process in the separation cylinder. a regeneration step in which the gas adsorbed or absorbed by the separating agent is removed from the separating agent and released under reduced pressure; A mixed gas separation apparatus in which a filling step of filling a part of the gas through a throttle mechanism to create a high pressure in the separation cylinder is sequentially repeated based on a certain time chart. Detection means for separately detecting predetermined control elements such as pressure and flow rate at predetermined detection points such as the cylinder, the inflow port, and the discharge port; a storage means for storing information in association with a time chart; and at a predetermined step of the time chart, the appropriate value of the control element at a predetermined detection point is retrieved from the storage means, and the actual value of the control element at a predetermined detection point is read from the storage means; a comparison means for inputting a value from the detection means and comparing it with the appropriate value; an abnormality detection means for detecting an abnormality when the comparison result of the comparison means does not match; and an abnormality detection means for detecting an abnormality when the abnormality detection means detects an abnormality. A mixed gas separation device comprising display means for displaying the same.
