1. INTRODUCTION 1.1 GENERAL

Bharat Petroleum Corporation limited (BPCL), the project proponent, is a fortune 500 oil

refining, exploration and marketing PSU with Navratna status company. BPCL is engaged

in refining and marketing of petroleum products. The company is India's one of the

largest commercial enterprises.

Oil marketing companies have projected an increase in demand of Liquefied Petroleum

Gas (LPG) in future due to increase in its domestic use. The demand is likely to increase

substantially over the years to come. Even in the present scenario it is very difficult to

meet the market demand of Kanpur and adjoining areas by Bharat Petroleum

Corporation Limited. As per directive of the Ministry of Petroleum and Natural Gas,

Government of India, different Oil companies are required to augment / construct new

facilities to meet the growing demand.

In line with the requirement envisaged and to ensure fulfillment of demand, Bharat

Petroleum Corporation Limited proposes to construct new LPG Bottling Plant facility at

it’s existing BPCL Kanpur POL Depot, near Bhaunti, PO-Panki, Tehsil: Kanpur Nagar,

Kanpur District in Uttar Pradesh State with a storage capacity of 3 X 1,450 MT. This

proposed plant shall meet the short supply of LPG Cylinders in the area and also decrease

BPCL’s dependence on other oil companies. This will also meet the present and future

house hold demands of people.

2 PROJECT DESCRIPTION

BPCL proposes to provide NEW 90,000 MTPA LPG Bottling Plant conforming to OISD 144

with LPG Storage in the form of 4,350 MT (3 x 1,450 MT) Mounded Storage Vessels which

will be distributed through LPG Cylinders in Kanpur and nearby areas.

2.1 PROJECT LOCATION

Bharat Petroleum Corporation Limited will install the 3 x 1450 MT LPG storage mounded

vessel along with other associated facilities in existing Kanpur POL Depot. The Land is

located in Bhaunti village, PO: Panki, Tehsil: Kanpur Nagar, District: Kanpur which is

about 4.38 kms away from Panki Railway station. LPG Plant plot Area is approx. 11.74 Ha.

4 PROCESS FLOW DIAGRAM OF LPG PLANT

5 SAFETY PHILOSOPHY

LPG is a common material used extensively in households as well as industry. If its

characteristics are understood well and proper precautions as stipulated in various codes

and standards are followed, it is an easy and safe material to handle. Accordingly, in most

of the developed / developing countries, where LPG is consumed in million tons / year,

specific codes and standards are available for storing and handling of LPG.

5.1 LPG INSTALLATIONS - CODES & STANDARDS

Codes and standards which are generally followed for LPG installations are as follows:

1. NPPA (National Fire Protection Association of USA) Standards

- NFPA-58 : Standard for the Storage and Handling of Liquified

Petroleum Gases

- NFPA-59 : LP-Gases at Utility Gas Plants

2. API (American Petroleum Institute) Standards



18

- API-2510: Design & Construction of LPG installations

3. IP (Institute of Petroleum) Standards .

- IP-9: Liquified Petroleum Gas - Large Bulk Storage of Pressurised

and Refrigerated LPG

4. The Static and Mobile Pressure Vessels (Unfired) Rules, 2016 of India

(SMPV Rules)

5. OISD (Oil Industry Safety Directorate) Guidelines

- OISD RP - 158 : Recommended Practices on Storage and Handling of Bulk

Liquified Petroleum Gas (LPG), 1997. (This is being followed by Public Sector

Refineries and Oil Industry in India. It is currently a guide and not a mandatory

code or standard).

LPG storage tanks take any other pressurised vessels may be designed as per any of the

following well known international or local codes / standards:

- ASME, Section VIII, Division I

- ASME, Section VIII, Division II

- BS 5500

- IS 2825

5.2 MOUNDED STORAGE FOR LPG

LPG is normally stored in above ground storage mainly spheres and cylindrical tanks,

namely, bullets & Horton spheres, the advantage being their accessibility for regular

inspection and maintenance which is important for such storage for hazardous service.

But these storages are susceptible to fire impingement and can give rise to Boiling

Liquid Expanding Vapour Explosions (BLEVE).

The reason for selecting mounded or buried bullets for LPG storage is to protect

them from direct flame impingement caused by any eventual fire in the

surroundings and thus prevent initiation of the sequence of events leading to an

occurrence of BLEVE.

The mounded storage concept basically originated from Europe and specialized codes

exist in Germany such as:



19

DIN 4681 Tl : Statutory Steel Pressure Vessels for Liquified Petroleum Gases for Earth

Covered Installations, Dimensions and Equipment.

During construction phase, a slight increase in the ambient noise levels is anticipated.

This impact will be temporary and limited to the construction phase. Hence no

permanent impact on this account is expected.

During the operational phase, no major social impact in the general area is expected.

There will be no change in the occupational structure of the workforce. As there will be

no emissions into air, no liquid effluents and no solid wastes no negative impact on the

health of the inhabitants in and around the project site is expected.

5.3 Water Resources

The total water requirement for the project and further during operation of plant i.e.

regular domestic use, fire fighting storage, drinking purpose etc. shall be done through

two bore Well within our premises.

5.4 Water Quality and Aquatic Ecology

The proposed LPG plant will not generate any process effluent. The only wastewaters

from the plant will be domestic effluent. The domestic wastewater will be treated

through septic tank followed by a soak pit. Water used for firefighting drills will be used

for gardening & water harvesting etc.

Hence no permanent impact will be caused on the environment on this account.

5.5 Air Quality

The dust from earthworks, vehicular emissions and the usage of D.G. set in case of power

failure are the only sources of air pollution from the site.

Power supply will be met by Uttar Pradesh State Electricity Board (UPSEB). There is no

requirement of steam hence no boiler and no emissions due to utilities. Since the



20

proposed facilities plan to receive, store and dispatch LPG there are no process emissions

as well.

Adequate heights of the stacks for atmospheric emissions help dispersing and diluting

pollutants to within the prescribed limits. In view of the above mentioned point there

will be no impact on the air quality. There will be no significant effects on air quality in

the context of human health.

During construction phase, a slight increase in noise is anticipated. This impact will be

temporary and limited to the construction phase. After the construction phase no major

increase in the noise level is expected. Hence no permanent impact on this account is

expected.

5.7 Environmental Hazards

The project proponents have designed all the safety aspects in planning, designing and

operation of the plant as per international practice. Such safety aspects are adequate to

take care of any hazard associated with the project.

5.8 Terrestrial Ecology

Any construction activity brings a significant change to the site top soil and some

components of the local terrestrial ecosystem. However, the adverse impacts are

restricted to the project construction site and to some extent its immediate vicinity. The

selected site is plain and leveled and will involve excavation and site preparation.

Rare or endangered species of flora and fauna do not exist in and around the proposed

site. Adequate green belt will be planted which will provide improved vegetation

habitat.
