1. ACTIVITIES

Since the creation of the refinery in 1963 and in accordance with national and international regulation, the security service is permanently responsible for the activities of :

• Security, peripheral surveillance and access control of the refinery ;
• Maintenance and test of machine operation ;
• Periodic training of different scenarios to control technical interventions ;
• Prevention of accidents and problems ;
• Assistance in work and construction sites ;
• Inspection of installations in compliance with security norms in force ;
• Implementation and follow up of the recommendations issued from certified Organisations.

2. MEANS OF IN

• 6 fire-fighter trucks ;
• Security emulsifier stock of 30,000 litres ;
• 517 fire extinguishers ;
• Varied prevention and civil protection equipment.

3. IN- HOUSE OPERATION PLAN

STIR has set up an appropriate intervention guide plan for each function inside the refinery with the following tasks :

• Elaboration of a danger survey to identify the major risks ;
• Study on model plan scenario ;
• Inventory of resources and intervention means for each scenario ;
• Definition of responsibilities and authorities.

4. REGIONAL AND NATIONAL INFLUENCE

The entire refinery’s potential is at the service of regional and national authorities.

STIR also participates with civil protection in any event or specific intervention.

ENVIRONMENT PROTECTION

STIR operates in the field of environment protection in accordance with environment laws and regulations into effect and focussed on :

• Making use of the necessary means in an effort to guarantee environment protection.
• Planing in place an anti pollution action.
• Being rigorous in the preventive approach.

WASTE

1. GASES

• Fuel oil and fuel gas combustion gases emanating from heating equipment of ovens, boilers and torches ;
• Gases emanating from the stocking park of oil products.

2. LIQUIDS

• Drain water ;
• Ballast water ;
• Cooling water.

3. SOLIDES

• Residuals black products at the bottom of stock age tanks ;
• Muds issued from water treatment plants.

WASTE RECYCLING

Since 1991, STIR has undertaken an antipollution action plan focussing particularly on :

• Improving the treatment of residual waters and solid wastes.
• Strengthening means of fighting against marine pollution.
• Other protection actions in favour of the atmospheric environment.
• Waste control.

This plan is based on the reduction of polluting emissions in the atmosphere, at sea and inland.

A. REDUCTION OF POLLUTING EMISSIONS IN THE ATMOSPHERE

REDUCTION OF EMANATION OF GASES INTO THE ATMOSPHERE

• Topping clearing project ;
• Installation of new exchanger on the crude pre-heating field ;
• Repair of the mixed combustion plant ;
• Maximisation of fuel gas combustion.

CONSIDERABLE REDUCTION OF HYDROCARBONS EMANATIONS INTO THE ATMOSPHERE

• Converting tanks with floating roofs into tanks with fixed roofs and a floating screen inside.
• Fitting large capacity tanks with floating roofs, with secondary seals or double seals.

C. REDUCTION OF POLLUTING EMISSIONS INLAND

• Regular control of the water table to fight against possible pollution by hydrocarbons .
• Acquisition of a cold water lorry for a regular cleaning of our sewage network.

B. REDUCTION OF POLLUTING EMISSIONS AT SEA

• Allocating a ballast tank for oil tankers ;
• Building four waste settling tanks ;
• Installation of an inverse osmosis unit to reduce acidulous or basic water discharge into the sea by reducing sulphuric acid resins of the demineralization process.
• Acquisition of VORTEX pumps to recover hydrocarbons in the case of accidental pollution at sea ;
• setting the necessary installation to recover H.C at the pier of the oil port in order to avoid marine pollution caused by an accidental discharge of H.C. ;
• Acquisition of floating dams to recover H.C at sea ;
• Acquisition of a Skimmer to skim and recover H.C accidentally discharged at sea and contained by a dam ;
• Installation of waste control analysers to prevent marine pollution and act on time and efficiently in case of pollution or bad treatment.
