Abstract
Systems for producing performic acid and methods for producing performic acid. The systems may include two or more reactor units, two or more servient programmable logic controllers, a control panel, and a master programmable logic controller. The system may modify the production of performic acid in at least one of the two or more reactor units upon and/or after the occurrence of a disruptive event in order to maintain a desired level of performic acid production and/or a desired level of disinfection.
Claims38
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.
A system for producing performic acid, the system comprising:
- at least one reactor unit, wherein the at least one reactor unit comprises a water bath and two or more coils disposed in the water bath;
- at least one servient programmable logic controller (sPLC), wherein the at least one sPLC is in communication with the at least one reactor unit;
- a control panel comprising a master programmable logic controller (mPLC) in communication with the at least one sPLC;
- and
- an automation unit having a user interface, wherein the automation unit is in communication with the mPLC.
