Batch Knowledge Centre
This tutorial wants to offer an introduction to the S88 Batch Control Standard of ISA,
The course is a product of the co-operation between the Batch Knowledge Centre and
Compex in the framework of the EET- project “Batch processes: Cleaner and more
efficient”.

S88 Introduction
Standard models and terminology
defining the requirements on
control for batch manufacturing plants
The S88 international standard provides standard model and terminology, which
emphasize good practices for the design and operation of batch manufacturing plants.
It can be used to improve control of batch manufacturing plants and can be appliedregardless of the degree of automation.

S88 Advantages
• Better communication• Easier adaptation for new products
The S88 standard provides a standard terminology and a consistent set of concepts
and models for batch manufacturing plants that will improve communications
between all parties involved and that will reduce the user’s time to reach full production levels for new products.

S88 Advantages
• Better communication• Easier adaptation for new products
• More appropriate batch control tools
• Better identification of needs
The S88 standard will enable vendors to supply appropriate tools for implementing batch control and will enable users to better identify their needs

S88 Advantages
• Better communication• Easier adaptation for new products
• More appropriate batch control tools
• Better identification of needs
• Straightforward recipe development
• Reduced cost of automation
The S88 standard makes recipe development straightforward and will contribute inthe cost reduction of automating batch processes.

S88 Definition Batch Process
In the S88 Standard, a batch process is a process that leads to the production of finite
quantities of material by subjecting quantities of input materials to an ordered set of
processing activities over a finite period of time using one or more pieces of
equipment. Batch processes are discontinuous processes. They are neither discretenor continuous; however, they have characteristics of both.

S88 Definition Batch
A Batch is
1. The material that is being produced or that has been produced by a single
execution of a batch process
2. An entity that represents the production of a material at any point in the process.

Process Model
The subdivisions of a batch process can be organized in a hierarchical fashion, called
the process model, or entity-relationship diagram. This process model consists of
four entities, the process, the process stages, the process operations and the processactions.

The process consists of one or more process stages which are organized as an
ordered set, which can be serial, parallel or both.

Process Model: Process Stage
A process stage is a part of a process that usually operates independently from other
process stages. It usually results in a planned sequence of chemical or physical
changes in the material being processed. Examples of a process stage are
“Polymerize”, “Recover”, “Dry”.

Process Model: Process Operation
Each process stage consists of an ordered set of one or more process operations.
Process operations represent major processing activities. A process operation usually
results in a chemical or physical change in the material being processed. Examples
of process operations are “Prepare reactor”, “Charge”, “React”.

Process Model: Process Operation
Each process operation can be subdivided into an ordered set of one or more process
actions that carry out the processing required by the process operation. Process
actions describe minor processing activities that are combined to make up a process
operation. Examples of a process operation are “Add material”, “Heat” or “Hold at
fixed temperature”.
