Claim 0:
1. A system for producing performic acid, the system comprising:
two or more reactor units, wherein at least one reactor unit of the two or more reactor units comprises a water bath and one or more coils disposed in the water bath;
two or more servient programmable logic controllers (sPLCs), wherein each of the two or more sPLCs is in communication with a different reactor unit of the two or more reactor units;
a control panel comprising a master programmable logic controller (mPLC) in communication with the two or more sPLCs; and
an automation unit having a user interface, wherein the automation unit is in communication with the mPLC;
wherein (i) the mPLC, (ii) at least one of the two or more sPLCs, and (iii) at least one of the two or more reactor units, are configured to maintain a desired level of performic acid production upon and/or after the occurrence of a disruptive event, and
wherein the two or more sPLCs are configured to detect the disruptive event and communicate a status of the two or more reactor units to the mPLC.
