OVERVIEW OF THE ORGANIZATION
Brief History:
Sitara Chemical Industries Ltd. Was incorporated in 1981 as a public
limited company and started its commercial production in 1984, under the
zealous administration of two brothers, Haji Abdul Ghafoor (late) and Haji
Bashir Ahmad.
Now Mr. Muhammad Adrees is the Chief Executive of SCIL. The factory is
situated at 32km Sheikhupura Road Faisalabad. SCIL incorporated under
the companies’ ordinance 1984 and listed in1987

Initially SCIL was incorporated for Chloral Alkali Production, however it
under gone merger with Gafoor Basheer Taxtile. SCIL has made growth by
leaps and bounds and Sitara Chemicals Industries LTD
become largest Caustic Soda producer in Pakistan. At present SCIL has a
market share of 70% in Caustic Soda industry.
Department of Electronics & Instruments
It comprises two sub departments which are responsible for the working of
the electronics parts in SCIL.
 Electronics Workshop.
 Instrumental Workshop.
Electronics Department:
We learned here
 Modules of PLC’s
Analogue IN/OUT
Digital IN/OUT
 Commmunication of DCS
Serial Communication
 Memories in PLC’s (EPROM,EEPROM)
 Differences & Advancements in S7200,S7300,S7400:
I/O’s
Response time
Memory (RAM, ROM)
Execution Time
Extendable cards i.e 2n
S7-200:
It has small memory,small applications,window based and low
performance as compared to others.

S7-300:
It has large memory than S7-200,long applications,programmable by the
Simatic manager and having high performance to the S7-200.
S7-400:
It has large memory,extendable CPU,long applications,extendable I/O’s
modules.
 Controller XP243 & XP233 in DCS
 Importance of Polarization.
 Switching Of Relays.
 Difference of UDP & TCP:
UDP(User defined Protocol)
TCP(Transmission Control Protocol)
 Cooling Circuit Measures in Rectifiers:
Deionized water outlet temperature
Air Cooling Temperature
Raw Water Inlet Temperature
 Inter_locking & Safeties of Rectifiers:
Thyristor Failure
Oil Temperatue Control
Moisture Control
Lock_out process
Tap changer unlock
Gas control
 Safeties Of Transformers:
Bucholz Relay

Instrumentation & Measurements Department:




In this Department we learned about:
How to control the main factors in which Instrumentation involved which
were there follows:
Pressure
Temperature
Flow
Level
Pressure:
We control the pressure in this industry by using different instruments at
different conditions.
We used the following instruments:
Temperature:
In SCIL temperature is kept controlled by a number of instruments which use the
temperature sensors and other instruments by which we can see the exact
temperature of the thyristors panel as well as the PLC panel.
The istruments which are used as follows:
 RTD(Resistance Temperature Detector)
 Thermo_couple:
Mostly used K-type but other types like J,T etc are also used.
 Thermistors:
Where the temperature & change range is minimum,then thermistors are
used.
The advantage of its usage in industry is this that it is low cost and
sensitive work.
 Gauges
 Pyro_meter:
It works on the principles of Infrared rays.

Where we can’t take contact at bus bars.
Here,Lenses are used for this process.
 Bi-metal Strips

Flow:
We used the simple flow_meter in SCIL programmed by microcontroller 8051.
Hence simply flow of all the materials is controlled by DCS systems from the CCR.
Level:
Level of the liquids and other materials are controlled by different instruments.
 DP Transmitters
 PT Transmitters
 LT Transmitters
 Level Gauge
 Side Glass
In above all the devices,DP Transmitters are the most accurate instrument
for detecting level of the liquids and chemicals in the tanks,vessels and in
chillers.
