2.0 INTRODUCTION

2.1 IMPORTANCE OF ENERGY CONSERVATION & ITS BACKGROUND

Energy is one of the most coveted inputs in the development of any society. With the

accelerated growth of the economy the demand for energy is increasing exponentially. On the

supply side the stock of the conventional energy resources like fossil fuel are limited and

rapidly depleting. India gradually becoming dependent on external sources of energy thereby a

considerable part of the GDP is exhausted for procurement of energy.

One of the easier available options for survival is energy conservation through energy

efficiency improvement; thereby reduction of energy consumption and cost there of through

strategic energy management concept and mechanism.

Energy conservation is a worldwide objective. The energy policy of the Government of India

also calls for conservation of energy. With the enactment of ‘Energy Conservation Act-2001’,

amongst others has emphasized upon the power of the appropriate Govt. to enforce efficient

use of energy and its conservation.

The management of OIL has adopted the energy system study and implements solutions

thereof with the objective to optimal utilization and output of available energy consuming

systems and to conserve energy.

In view of energy efficiency improvement and cost reduction program for long-term business

solution the management of OIL sought the services of PCRA for energy system study on Gas

Compressors, air compressors and Lighting systems at their plant at Duliajan in Assam.

PCRA has studied the energy systems of the plants accordingly with the help of OIL

representatives. During the study, the energy audit team has mapped present status of

electrical power and energy systems at the plant premises, identified areas of weaknesses,

major energy loss areas etc. The study has identified potential scope for improvement and

energy efficiency improvement in major energy consuming systems. It also recommends cost

effective and fast pay back solutions for energy cost control.

2.2 COMPANY PROFILE

The story of Oil India Limited (OIL) traces and symbolizes the development and growth of the

Indian petroleum industry. From the discovery of crude oil in the far east of India at Digboi,

Assam in 1889 to its present status as a fully integrated upstream petroleum company, OIL has

come far, crossing many milestones.

On February 18, 1959, Oil India Private Limited was incorporated to expand and develop the

newly discovered oil fields of Naharkatiya and Moran in the Indian North East. In 1961, it


---------------------------------------------------------------------------------------------------------------


became a joint venture company between the Indian Government and Burmah Oil Company

Limited, UK.

In 1981, OIL became a wholly-owned Government of India enterprise. Today, OIL is a premier

Indian National Oil Company engaged in the business of exploration, development and

production of crude oil and natural gas, transportation of crude oil and production of LPG. OIL

also provides various E&P related services and holds 26% equity in Numaligarh Refinery

Limited.

The Authorized share capital of the Company is Rs. 2000 Crores. The Issued, Subscribed and

Paid share capital of the company is Rs. 601.14 Crores. At present, The Government of India,

the Promoter of the Company is holding 78.43% of the total Issued & Paid-up Capital of the

Company. The balance 21.57% of the Equity capital is held by others.

OIL has over 1 lakh sq km of PEL/ML areas for its exploration and production activities; most of

it is in the Indian North East, which accounts for its entire crude oil production and majority of

gas production. Rajasthan is the other producing area of OIL, contributing 10 per cent of its

total gas production.

Additionally, OIL’s exploration activities are spread over onshore areas of KG Basin, Mahanadi

Basin, Cauvery Basin, Andaman Basin and Gujarat-Kutch Basin etc. OIL also has participating

interest in NELP exploration blocks in Mahanadi Offshore, Mumbai Deepwater, Krishna

Godavari Deepwater, etc. as well as various overseas projects in Libya, Gabon, Iran, Yemen,

Nigeria, Sudan and Venezuela.

In a recent CRISIL-India Today survey, OIL was adjudged as one of the five best major PSUs and

one of three best energy sector PSUs in the country.

Objective of Energy Audit

With the advent of energy crisis and exponential hikes in the costs of different forms of

energy, Energy Audit is manifesting its due importance in Industrial Establishments. Energy

Audit helps to understand more about the ways energy and fuels are used in any

Establishment and helps in identifying areas where waste may occur and scope for

improvement exists.

Energy Audit is the key to a systematic approach for decision-making in the area of energy

management as it attempts to balance the total energy inputs with its use and serves to

identify all the energy streams in a facility/ Establishment.

It was with this objective that Petroleum Conservation Research Association (PCRA) was

entrusted by OIL, the Energy Audit of Gas Collecting Station#1, Duliajan.

3.3 THE POWER SYSTEM:

The source of power supply for GCS-1 is from CPP at 3.3 kV for HT supply to the 2 nos. of

Motor driven Gas Compressors (1 no. Gas Lifter & 1 no. Low Pressure Booster). Another

transformer is present (3300 volt / 415 volt of 400 KVA) for LT supply to lighting & Air

Compressors and smaller motors.


---------------------------------------------------------------------------------------------------------------


Fig.1, shows percentage share of electrical power consumption by major equipment at the OIL-

GCS plant:

Observation :

� It is observed that the major portion of the electrical power is consumed by the HT

motors (LPB-4 and GL-5).

� Monitoring of electrical power consumed by the plant is not practiced at present.

Energy monitoring and targeting is primarily a management technique that uses energy

information as the basis to eliminate wastage, reduce and control current level of

energy usage and improve the existing operating procedures.


---------------------------------------------------------------------------------------------------------------


4.0 STUDY OF AIR COMPRESSOR

4.1 AIR COMPRESSOR DETAILS

The compressed air system of GCS-1, Duliajan has two reciprocating type air compressors. One

is of 15 kW and the other one is of 30 kW capacities.

Air compressors are connected to common receivers. Air is supplied at 14 kg/ cm2 for cranking

operation of the gas engines of gas compressors during start-up. Air @ 6 kg/cm2 is required for

the pneumatic control of the gas engine valves & circuit.

Pneumatic air taken from the air receiver passes through a pressure reducing device and air

dryer and supplied to various pneumatic systems @ 6 kg/cm2.

Air Pressure of 14 kg/cm2 is only required at the time of start-up of the gas engines and once

the engines are started then 14 kg/cm2 pressure is not required. Continuous air pressure is

only required for the pneumatic control valves & circuit of the gas engines and that too at 6

kg/cm2 pressure.

In present condition the air is maintained from 10 kg/cm2 to around 14 kg/cm

2 at any point of

time. The unloading of the air compressor is done at around 14kg/cm2 and the loading is done

at 10 kg/cm2.

Hence in the above condition it is clear that although the air pressure requirement of 14

kg/cm2 is only required during starting of the Gas engines but still the pressure is maintained

from 10 to 14 kg/cm2 throughout the day in order to start any engine when sudden

requirement is there.

The performance of the Air Compressors could not be checked as the compressors could not

be isolated due to operational inconvenience.

It should be noted that more power is required to compress air at higher pressure compared

to lower pressure i.e, energy required to compress air from 10 to 14 kg/cm2 is much higher

compared to pressurizing air from 3 to 6 kg/cm2.


---------------------------------------------------------------------------------------------------------------


RECOMMENDATIONS :

At GCS-1, compressed air is used for two purposes:

1. To start Gas compressor engines (pressure requirement 14 kg/cm2).

2. To drive pneumatic instruments (pressure requirement 6 kg/cm2).

Pressure requirement for both the works are different as mentioned above.

It is recommended to maintain different air receivers for 14 kg/cm2 and 6 kg/cm2 line pressure.

Also one of the compressors should be dedicated to 14 kg/cm2 and the other one for 6 kg/cm2

line so that total running time of both the air compressors would reduce in a day.

To have redundancy in operation of the air compressors, one bypass line can be connected

from both the air receivers with a valve in-between so that whenever one compressor is under

shutdown then the other compressor can be compensated.

With an estimated min. of 25% of energy can be saved with this kind of arrangement.

Since the Station is going for a new air compressor house hence it would be easy to carry out the

recommendation.

Investment for this recommendation = The buried old air lines need to be replaced which need

investment. The need of investment is to be estimated.

Monetary value of energy saved per annum @ Rs. 4.55 per kWh = 30016 x 4.55 = Rs. 1.36 Lacs

Note: The equivalent gas consumption for motor is based on the gas consumed to generate power

at Duliajan Gas based Power Plant.

5.2 REPLACEMENT OF MOTOR DRIVEN COMPRESSORS WITH GAS ENGINE DRIVEN TO

CONSERVE POWER

It was informed to us by OIL personnel that power consumption by existing motor driven

compressors are much higher, replacement of the same with gas engine driven

compressor unit to be assesed for effective utilisation of power.

Therefore, following calculation is given to assesss the cost of replacement of Compressor

Motors with New Gas engines.


---------------------------------------------------------------------------------------------------------------


By matching the RPM of the Gas compressors and BHP of the present Electric Motors, it is

found that Waukesha Dresser F 3521GL is suitable for replacing motors of GL-5 and LPB-4.

As per the data sheet the compressor is having Compression Ration of 10.5:1, RPM of 1000

and BHP of 615.

The fuel consumption at full load is 110.6 m3/hr. as the load curve the fuel consuption at

60% load as per design will be 98 m3/hr

Cost of purchasing the Gas Engine is $1,65000 = 1,65000 X 55= Rs. 90075000/-

The cost of running one Gas engine is 98 X 24X365 = 858480 X Rs.8.83 (Cost of NG) = Rs.

7580383.00

Present average power consumption of running motor is 226.75 Kwh

Cost of running of one motor is 226.75 X Rs.4.55 X24 X365 = Rs. 9037801/-

Saving for Gas Engine per year = 9037801-7580383= Rs. 1457418/-

Payback = 90075000/ 1457418 = 61 Years

Therefore, it is economically not feasible to replace a motor with a gas engine. But, in case

of non-availability of power gas engine can be procured.


---------------------------------------------------------------------------------------------------------------


6.0 ILLUMINATION SYSTEM

6.1 SUMMARY OF LUMINAIRES

The illumination level in the GCS – 1 is on the lower side. Average lux level maintained in the

roads, pathways etc. are in the range of 1 – 10.

The lighting at the main entrance and also in the pipeline manifold area is very poor which

needs to be improved.

The street lights are fitted with HPSV and the shed are fitted with MLL& HPMV fittings. There

are some 36 watt FTL present in air compressor house & other office areas as well.

The average lux level in different areas are shown below:

Area LUX Level Recommended Lux

Gate Entry 0 - 5 30 – 50

Pathway 0 -10 30 – 50

Pipeline Manifold 0 - 5 30 – 50

Small Shed 2 - 25 50 – 100

Large Shed 5 - 15 50 - 100

Air Compressor Shed 30 - 150 100 - 150

6.2 RECOMMENDATIONS AND PAYBACK ANALYSIS:

1. Replace all the conventional 40 watt and 36 watt tube light (Fluorescent Tube Light)

with energy efficient T5 (28 watt).

2. Use reflector in FTL systems and other present lighting system to get better lux level at

working height.
