CHENNAI PETROLEUM
CORPORATION LIMITED
CPCL is conducting
Oil & Gas conservation Fortnight on an annual basis, during
the second fortnight of January, as per the directives of Ministry
of Petroleum and Natural Gas (MOP & NG) in line with other
oil companies. The areas covered, during OGCF, are given below.
The conservation
measures practiced, at CPCL, during normal operations, are also
given below.
I. Activities
covered during OGCF
1. Mass Awareness & Education Campaign
• Putting an Oil Conservation pavilion
• Human chain with banners and placards and slogans.
• Dissemination of Oil Conservation message through banners, posters, booklets/
pamphlets and stickers.
• Conducting Quiz, Drawing and Essay competition in schools/ colleges in
and around the city.
2. Transport
Sector
• Clinics for drives of Auto / Taxi and Heavy vehicles with emphasis on
good driving habits
• Emission checks for vehicles and tuning
3. Household
Sector
• LPG / Kerosene clinics for housewives in the city
• Demonstration of fuel-efficient stoves, lighting appliances and utensils
(pressures cookers etc.) were to the public.
• Printed materials highlighting the necessity to conserve LPG and Kerosene
and talks on good cooking habits were organized.
4. Agricultural
Sector
• Emphasis on the need for saving diesel and Lubes in the operation of
tractors, irrigation pumps, and farm equipments
• Industrial Sector
• Technical Seminars
• Quiz, LPG clinic, Cooking Competition etc.
II. Conservation
measures practiced, at CPCL, during normal operation
1. Furnaces
Operation
A. Furnace optimization by controlling
i. Continuous monitoring of excess air in furnaces/ boilers with corrective
action to obtain optimum efficiency
ii. Controlling Draft
B. On-line
Furnace maintenance
i. Minimize air ingress into furnace
ii. Periodical Soot Blowing for oil fired heaters
C. Shutdown
Furnace Maintenance
i. Internal cleaning (Steam – Air decoking). Need is determined by monitoring
tube metal temperatures.
ii. External cleaning
2. Advanced
Process control, trading off between energy cost and yield benefits:
i. Optimal
reflux ratio / operating pressure within tower physical restraints
and target product compositions
ii. Maximize pump around reflux to improve heat recovery to feed
iii. Pre-heat pick-up – Control of heat integrated units utilizing hot
feeds
iv. Fired heater advanced computer control
v. Control steam stripping by adjusting steam rate to maintain Steam/ Product
or Steam / Catalyst ratios.
3. Attending steam leaks and fully steam traps. “Call Center” concept
is being followed.
4. Minimum usage of pressure reduction station for matching steam pressure
5. Condensate recovery
6. Electrical Energy conservation areas:
i. Motor selection based on life-time cost
ii. Replacement of oversized motors
iii. Using variable speed induction motors for pumps, fans & blowers
iv. Power factor improvement
v. Improvement of operational parameters and lighting
7. Reduction
of flaring losses
i. Usage of John Zink ZOOM control on each flare to reduce steam to minimum
(3000 lb/hr). Further, video camera is installed for viewing the flare and
adjusting the steam for smokeless flaring
ii. Installation of flare meters
