VOC Control, Emission and Monitoring:

In petroleum complexes, the release of volatile organic compounds (VOCs) to air depends on

the products handled at the plant and may include acetaldehyde, acetone, benzene, toluene,

and xylene. VOC emissions are mostly fugitive and depend upon the production processes,

material handling and effluent treatment procedures, equipment maintenance, and climatic

conditions.

These fugitive emissions originate from the static and dynamic compressor joints and seals

used in flanges, pumps, valve packings and connection joints to the atmosphere like sampling,

relief valves, etc.

8





Document No.

A257-SR-II-1741-1301


In order to minimize the fugitive emissions, the following measures will be taken:

Minimum number of flanges, valves, etc.

High grade gasket material for packing

Usage of state-of-the-art low leakage valves preferably with bellow seals

Usage of pumps with mechanical seals

Provisions of floating roof storage tanks

Provisions of double seal in some of storage tanks

Provision of seals in the drains and manholes

For VOC monitoring, recurring cost of Rs.14.00Lakh/annum has been estimated in the

operational phase of the project.

A regular Leak Detection and Repair (LDAR) program/survey is carried out within the refinery

complex annually. A summary of the procedure adopted is as follows:

The monitoring procedure, will be in compliance with ISO/DIS 14001, and uses a similar

procedure to that detailed in “Guidelines for Environmental Auditing—General Principles”,

AS/NZS ISO 14010 (Int) 1995.

The monitoring procedure for each of the operations is included:

A) Monitoring Preliminaries:-

i. Review of Process and Instrumentation Diagrams (P&IDs), Process Flow Diagrams (PFDs)

and other information

ii. For each facility P&IDs, PFDs and other information will be reviewed to identify all emission

points. Where appropriate screen or group those emissions points. For example:

Screening – Pressure safety valves (PSVs) are screened from further analysis as the

frequency of release is considered to be low and they are required for the safe operation of

the plant.

Grouping – Fugitive emissions of hydrocarbons (H/Cs) from vents are grouped as fugitive

emissions.

iii. Opening meeting

At each opening meeting an outline is given of the objective and the methodology to be used

for the monitoring. Requests are made for specific environmental documentation and

personnel.

B) Conduct the Audit

9





Document No.

A257-SR-II-1741-1301


i. Review Emission Points Detailed on the P&IDs

With the assistance of operations personnel the emission points identified in the P&ID will be

reviewed. From the P&IDs, it will be determined whether sampling needs to be undertaken

and what emission points should be sampled.

ii. Review Monitoring Undertaken to Date

Operations personnel will review environmental monitoring that may have been undertaken to

date and will obtain, where possible:

Fuel gas analysis, in particular the sulphur concentrations

Fuel gas flow rates (note: fuel gas flow rates will enable mass emission rates of emissions to

be determined.

iii. Undertake an Inspection of the Facility

iv. Inspection of the facility will verify the information supplied and to establish the ability or

otherwise, to undertake programmed sampling.

v. If required, Undertake Representative Sampling

Depending on monitoring undertaken to date, and the accessibility to sample point locations,

sampling of gaseous or liquid effluents will be undertaken, as deemed necessary.

C) Undertake a Close-Out Meeting with the Operations Personnel

Brief outline of the findings with regard to emission point identification, stream characterization

and mass emission rate determination will be provided.

Conclusion:

For Methane hydrocarbons, comparing the A and B data in Table 1.2, none of the locations

have shown the presence of Methane hydrocarbons except for data collected in village

Dhanateja. This might be due to escape of unburnt volatile gases from the Refinery Flare as the

location in very close proximity to the Refinery Flare.

For non-Methane hydrocarbons, on comparing C and D data in Table 1.2, there hasn’t been a

significant/considerable difference in the values reported in the locations where the presence of

non-methane hydrocarbons showed. The difference is not considerable and the difference might

have come due to the seasonal variations or during the analysis of the samples collected.

So, it may be finally concluded based on the re-analysis study that the study area around the

Mathura Refinery is free from the Methane and Non-methane hydrocarbons.

Annexure-II

Point – 2 : Maximum Predicted Impact due to SO2 emissions to be ascertained and modeling to be developed for SO2 to be correlated with CPCB data Mathura Refinery was established with utmost care for environment after having done the first

ever scientific study for assessment of impact on environment prior to commissioning of the

Refinery (Environmental Impact Assessment) during 1975-77 by the Expert Committee under

the Chairman of Dr. S. Varadrajan, the then Chairman & MD, Indian Petrochemical Corporation

Ltd. The study covered (a) the pollutant levels prevailing in the Agra Region by NEERI and (b)

Dispersion of Pollutants from refinery by IMD and Teeneco of Italy. The study involved

determination of Sulphur Dioxide at various distances from refinery site under different

Meteorological conditions. The committee recommended a limit of1000 kg /hr Sulphur dioxide

emission from refinery stacks and predicted that the impact of about 1-2µg/Nm3 at Agra Region

and 0.3 µg/Nm3 at Bharatpur region in 1975.

Mathura Refinery was commissioned in 1982 with a permission of 1000 kg/hr sulphur dioxide

emission from refinery stacks. In Oct’1993, under the directive of the Hon’ble Supreme Court,

coveted institute for Environment, NEERI carried out detailed study for the reduction of SO2

emissions from the refinery. The study recommended short term and long terms steps for

reduction of the SO2 from the limit of 1000 kg/hr to 450 kg/hr. The reduction in sulphur dioxide

emission level over a period of time is as under:

Prescribe limit (Kg/hr) Actual values (Kg/hr) Remarks

1000 (Mar-Sep)

700 (Oct-Feb)

530-600

360-450

Use of Natural Gas

commenced Dec’96

450 (entire year) 300-380 2000 onwards

The various recommendations given by NEERI and in-house projects were implemented during

1995-2000 in order to bring down the SO2 emission below level of 450 kg/hr. Major ones are

given as under

a) Low Sulphur crude processing: Processing of low Sulphur crude (40% of the total crude

processed) viz. Bombay High and Nigerian Crude.

b) Use of clean fuel in furnaces: Since, Dec’96, Natural Gas is used in furnaces to meet major

heating requirement. Approx 60% of total energy need is met by Natural Gas. Refinery Fuel Gas

is used after de-sulphurization to reduce H2S less than 100 ppmv. Low sulphur Liquid fuel

(Finance oil) having ‘S’ less than 1% is used. It reduces both SO2 emission as well as

particulate matter emission.

c) Sulphur Recovery Units: New SRU units with 99% + sulphur recovery was installed and

commissioned in 1999. In 2005, Tail Gas Treatment Unit was installed and commissioned to

achieve more than 99.5% sulphur recovery. In 2010, one new SRU was commissioned to have

a provision one unit always as a hot stand-by.

d) Hydro Cracker Unit –Hydrocracker unit was commissioned to produce BS-III & IV grade

automobile fuel. OHCU also provided hydro-processed feed to FCC. Presently, 30% FCC feed

in hydro-processed (OHCU Bottom) which significantly decreased SO2 emission from FCC unit.

e) Tall chimneys: For better dispersion of pollutants in atmosphere so that the Ground Level

Concentrations are kept at the minimum tall chimneys are provided in furnaces. All units are

having stacks ranging upto 90 meters.

f) Creation of Pollution Sink (Green Belt): As Green cover acts as a natural sink to pollutants,

Mathura Refinery has done extensive tree plantation within the refinery & township area as well

as far flung areas since inception. Till date, more than 2.89 lakhs trees planted around Agra &

Mathura region to convert refinery operations carbon neutral.

Since starting, SO2 emission from refinery was maintained always below the prescribed limit.

The plot below represents emissions for over past 30 years:

SO2 Monitoring Activities by Refinery: To measure the SO2 concentration in the ambient air

and keep track on the impact on surroundings, Mathura Refinery has established 4 continuous

monitoring stations outside the refinery.

Air Quality Prediction using ISCST3 MODEL in Agra City:-

There were 2 stations out of 15 stations, situated within Agra City and are about 25 KM away from Refinery to record the ground level concentration of pollutant. This baseline environmental data in the study period represents the emission level in existing scenario and includes the impact of the emissions from the existing facilities. The ground level concentration for SO2 was predicted in 50 KM radius using Industrial Source Complex Version 3, which is an AERMOD dispersion modeling program designed to estimate pollutant concentrations for simple, intermediate, or complex terrain.

In order to find any impact on Taj Mahal and TTZ zone, Air modeling is conducted for 50 kms radius from Mathura refinery and isopleth obtained is given below. The model shows that the air impact has already dissipated in this range itself and practically, there is no impact coming on

Taj Mahal. However, some minor impact of 5-6 g/m3 is noticed around 25 kms radius which further reduces towards Taj Mahal which is around 41 kms in south east direction from Mathura refinery.

Control of SO2 emissions: For control of SO2 emissions, SRUs, ARUs, TGTU, Palletizer and plantation activities have been suggested. For this activity, an amount of Rs. 112265.00 lakhs as capital cost and for additional plantation activities, recurring cost of Rs. 8.0 lakh/annum in addition to the capital cost has been estimated. Conclusion: Based on the Isopleth drawn for the capacity expansion, it has been concluded that the SO2 emissions resulting due to the capacity expansion is well within the limits as per the NAAQS for the study area of 25 km. When we examine the same for 50 km radius , the SO2 emissions has practically no effect on the Taj Mahal. Isopleth obtained for SO2 emissions in 50 kms radius from Mathura refinery including the location of Taj Mahal is shown in figure-1.9 below.

Point – 3: Item-wise details along with time bound action plan for ESR (Enterprise Social Responsibility) for construction phase to be prepared and submitted As a part of Guidelines on Corporate Social Responsibility for Central Public Sector Enterprises,

dated 09.04.2010 from Ministry of Heavy Industries and Public Enterprises, IOCL, Mathura

Refinery has been implementing various projects in order to bring socio-economical progress in

the surrounding region.

Mathura Refinery undertakes these projects – short term and long term in consultation with

District Administration, request received from Gram Pradhans and based on the

recommendations of baseline survey for identified villages around the Refinery. The survey

focused on requirement of infrastructural facilities for schools like buildings, drainage, roads,

drinking water facility, provision of teaching aids/ equipments, library, table and chairs etc.

The Social Impact assessment study was carried out by Tata Institute of Social Science and

Engineers India Limited in 5 KM radius of Mathura Refinery as a part of EIA study for the

proposed capacity expansion project of Mathura Refinery. In the SIA study, focus areas for

social up-liftment have been identified as Medical and Health care, Clean Drinking, Sanitation,

Education, Infrastructure etc.

In compliance to the MoEF query, IOCL, Mathura Refinery shall be implementing project with

the cost of Rs 11.0 Crores during the 4 years of project construction phase in the aforesaid

areas for social up-liftment.
