A strategy for carrying out a contiguous process within a unit. It consists of contiguous operations and the algorithm necessary for the initiation, organization, and control of those operations.
A unit procedure consists of an ordered set of operations that cause a contiguous production sequence to take place within a unit. Only one operation is presumed to be active in a unit at any time. An operation is carried to completion in a single unit. However, multiple unit procedures of one procedure may run concurrently, each in different units. Examples of unit procedures include the following:
* Polymerize VCM.
* Recover residual VCM.
* Dry PVC.
