Major incident investigation report -
BP Grangemouth Scotland :
29th May - 10th June 2000A public report prepared by
the HSE on behalf of the Competent Authority

Summary description of the BP Grangemouth complex and overview of the Management Structure
Overview of the Processes and Products at the Complex Three business streams are present on the
Complex.
Exploration business stream
This business includes the Forties Pipeline
System (FPS) which is routed into the Oil & Gas Processing complex at
the Kerse of Kinneil. This is situated on the northern side of the A904 Bo’ness
road to the east of the river inlet. The Exploration Business Stream
provides the raw materials for use in the Oil Refinery and the
petrochemical plants. The oil and gas arriving at Kinneil go through a
two-stage process of heating and separation to produce a stabilised crude
oil and raw gas streams. The crude oil is then either exported directly
from the Complex or supplied to the Oil Refinery.
Oil business stream
This business consists of the Oil Refinery
which is located in the middle of the North Side. It processes stabilised
crude oil and has an annual capacity of around ten million tonnes. At the
Oil Refinery several processes occur:
-
Distillation
which is the process of product separation by boiling;
-
Conversion
and upgrading which are processes whereby low value products are
turned into more saleable products;
-
Purification
which is the process of removing contaminants before final blending
and shipping to market.
The major products from the Oil Refinery
include liquefied petroleum gas (LPG), petrol, diesel, jet fuel, kerosene,
fuel oil and heating oil. Naphtha is produced and fed into the
petrochemical processing facilities.
Chemicals business stream
This business consists of a number of
petrochemical plants which are located on both the North and South Sides.
The petrochemical plants use gas separated from the oil as their main
feedstock to produce petrochemicals. Initially by a process known as “cracking”
the mixed raw gases fed from the Kinneil operations (a complex mixture of
large and small gas molecules) are broken down into smaller molecules
which are then used as feedstocks for a range of petrochemical plants.
These plants produce a range of products including ethylene, propylene,
benzene, ethanol, and polymers such as linear low density polyethylene and
polypropylene. These chemicals are sold as basic raw materials for a
number of further industries including textiles and pharmaceuticals.Further detail on the facilities at the
Complex can be obtained from the BP website at www.bp.com.
