Why do we need an effective process

Control...?

Reduce the operating cost To ensure the safe bounds of operating to protect the personnel,

equipment and environment.

To Hold the operation with in the physical limitation of the equipment

To Meet Product Specification



2006 Borouge


To manipulate the input & output of energy & materials through a

process to keep the process variables with in desired limits.

For Training purpose only

A series of actions performed to create a product.

Is the intervention that guide the process back on to

the track following any upset or disruption.

Any characteristic of the process that change duringprocess, The most common process variables are: Pressure, Flow, Level,

Temperature, Speed, etc.


2006 Borouge


The process must be kept stable and notallowed to exceed safe constraints to prevent damage to equipment,

injury to personal and loss of material and energy and safe for the

environmental.

is defined as a process where all process

variables are with in their normal operating constraints and all

variables are respond normally and predictably to control changes

: Quality control is initiated until the process isoperating with stability.

adjustment must always be kept with in the

constraints in maintaining the process stability

A collection of module ,each with its own specific function,

Interconnected to accomplish coordinated data acquisition and control


It provides:

Measurement

Control Loop

Motor Control

Sequences

Process Diagrams

XCV-Control Valves

2006 Borouge


The Process Variable tobe controlled

A Measuring Device todetermine the value of the

variable

A Controller (decisionmaker) to control the

variable at a desired value

The Final ControlElement that performs the

action on the variable, which

is usually a valve.



2006 Borouge


In manual mode, the

operator becomes the

controller. The

operator observes the

value of the process

variable, make a

control decision, then

manipulates a valve

Borouge reference line 2006

2006 Borouge


In Automatic mode, An Automatic

process variable controller

consists of a comparator that

receives a measurement signal

and a set point signal. The output

signal from the controller is sent to

a control valve, or other final

control element


11


2006 Borouge


In Cascade Control mode,

Cascade control links controllers in

series, with the output of one

controller resetting the set point of

the next controller in line. An

example of this type of control

scheme is a tank level controller

that operates the set point for a

flow controller


12


2006 Borouge


High and Low Signal Selectors

are often used for override

controllers. When two, or more,

controllers are able to signal the

same control valve, a signal

selector will choose which

controller will send the active

signal to the valve.

The interlock is the protection system designed toautomate the required operator actions during an abnormal

event effecting the process that may result in major

equipment damage, injury personal, environmental issues,

long down time and / or loss production

There are DCS Interlock and ESD Interlock

The Borealis Borstar PE process design is such that a separateemergency shutdown system is required due to the characteristics of theprocess. A programmable TMR ( Triple Modular Redundant) electronic

shutdown system is used for this process.

Special attention has been paid to the speed of data transfer betweenDCS and ESD in applications where on-off valves are used for ESD and on-

off control operations. The ESD communicate with Honeywell DCS directly via

a node on the UCN. This is a fully redundant link. Battery limit ESD valves

(e.g. EU to PE) have manual reset ESD solenoid valve and separate DCS

solenoid valve where applicable.

To safeguard the process mechanical devices are provided in addition tothe emergency shutdown system.
