Introduction TutorialS88Batch ControlThe
International Society for Measurement and Control
(ISA)
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 terminologydefining the
    requirements oncontrol 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
applied regardless of the degree of automation.
3
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 users time to reach full
production levels for new products.
4
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
5
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 in the cost
reduction of automating batch processes.

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
  • Reduced life-cycle engineering efforts

The S88 standard will contribute in the reduction
of life-cycle engineering efforts.

S88 Definition Batch Process
Quantities of input materials
Finite quantities of materials
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
discrete nor continuous however, they have
characteristics of both.

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

Process Model
Process
Process stage
Process operation
Process action
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 process actions.
10
Process Model Process
Process
Process stage
Process operation
Process action
The process consists of one or more process
stages which are organized as an ordered set,
which can be serial, parallel or both.
11
Process Model Process Stage
Process
Process stage
Process operation
Process action
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.
12
Process Model Process Operation
Process
Process stage
Process operation
Process action
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.
13
Process Model Process Operation
Process
Process stage
Process operation
Process action
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.
