2 1. FACTS The Refinery was shut down in 2010, after a significant two years maintenance and revamping program in the range of a three digit million US$. This program increased reliability, reduced maintenance costs and implemented improvements in key refinery units, which further improved yields and processing capability. Following the completion of the described turnaround program, the next turnaround is not required for next five to six years. Asset Description Crude oil throughput capacity of approx 90,000bpd Atmospheric/vacuum distillation; reforming; catalytic and thermal cracking; visbreaking and bitumen Solomon complexity: 7.7

4 Construction Two phases In the early 1960s, the following main units were erected: the crude and vacuum distillation unit, the visbreaker/thermal cracker units, The naphtha hydroteater, the gasoil hydrodesulfurization unit and the catalytic reformer unit In the early 1980s, the following units were added: A new vacuum unit A fluid catalytic cracking unit New boiler and installation of a gas turbine Cryogenic unit to recover LPG from the fuel gas Major revamps and debottlenecks FCC reaction section was significantly revamped in 2010 Visbreaker / thermal cracker units were revamped in 2005 Extractive Merox to remove mercaptans from FCC LCN in 2004 The Gas Oil hydrodesulphurization unit was debottlenecked in 1996 The catalytic reformer reactors were replaced between 2000 and 2004 Third stage filter of the FCC Flue gas in 2000 A new Claus unit was installed in 1996 The refinery has been operated from one single control room since 1996 On average, every five years a major maintenance turnaround has been performed In short, a refinery in good shape thanks to continuous improvements

5 Modifications and projects All the modification projects were conducted following the Design Engineering Practices of SHELL (DEPs) recognized as some of the best standards in the world. Maintenance and Reliability Over the years, the routine maintenance of the refinery was performed according to the standards of the refining industry The critical equipment items (compressors, big pumps, ) were tightly monitored and received an adequate maintenance program (preventive maintenance) In the period , the mechanical availability (excluding slowdowns) was 95% and operational availability 91% Health and Safety The refinery has well-established systems to manage personnel and process safety and an excellent track record in terms of incidents and accidents These systems adhere to French regulatory standards and industry best practices The refinery operator has continued upgrading the working standards and environment in accordance with heightened industry standards following the BP Texas City Refinery incident In total, the refinery operator has spent $9.2 M in safety-related projects between 2008 and 2010 a safe workplace in a good state of preservation!

6 Since 2008, the refinery operator and owner has invested a total amount of $120 M at the refinery, in four main areas: Investments to improve Health, Safety, Environment and Quality, which addressed key issues pertaining to risk reduction and control enhancements Investment to improve reliability targeted mainly at the FCC, power systems including gas turbine cogeneration unit and crude distillation tower Comprehensive maintenance and refurbishment requirements of all units. This segment represents 54% of all capex spent since 2008 While the main focus has been on improving reliability of the site, the refinery operator has also completed profit-enhancing projects aimed at increasing processing capabilities, increasing yields of high-value products and increasing hydrotreating capabilities Following these investments, the refinery was ready for a continuous run of 6 years!

7 The refinery s low-sulphur products meet the EU specifications Maximum sulphur limit of 10 ppm for gasoline and diesel, and 1,000 ppm for heating oil On yearly and daily averages, NOx emissions are below 500 mg/ Nm3 (European legislation threshold) when significant fuel oil amounts are burned. Firing only natural gas (in the furnaces) would reduce this value to 350 mg/nm3 On yearly and daily averages, SOx emissions are below 1700 mg/nm3 (European legislation threshold) when significant fuel oil amounts are burned. Firing only natural gas (in the furnaces) would reduce this value to 800 mg/nm3 On the Claus units, the sulphur recovery (from H2S) is slightly above 95%. Engineering studies have been completed on a very efficient technology called Sub Dew Point where the sulphur recovery is more than 99.5%. Based on our simulations, this technology coupled with firing natural gas would reduce daily SOx emissions to 600 mg/nm3 Water treatment units have been designed to process water (groundwater, rainwater, oily water..) very efficiently. The treated water is discharged to the Rhine river where specifications are very tight In terms of particulates, the target of 50 mg/m3 (daily and yearly) is achieved thanks to very efficient systems on the FCC unit Thanks to good thermal integration, fuel consumption is on average below 5% of the crude throughput. Consequently, CO2 emissions are below the approximately 540 ktpa limit that is allocated to the site excellent environmental capability!

8 People Experienced and responsive technical staff remain available to assist in dismantling activities and to provide advice to potential purchasers The refinery operator recognises that some customers will want a fast-track dismantling project and remains able to accommodate this Documentation Most of the documents produced since the commissioning of the refinery have been saved as hard copy. The most important ones are also available in electronic format: PFDs, P&IDs, Isometrics & specification sheets Operating manuals and operating procedures are available in electronic format On a regular basis, test runs were performed on the different units. For the last ten years, all the records are available as electronic files The refinery was certified to ISO9001, ISO14001 and the laboratory was certified ISO17025 Access to above will be controlled via Lohrmann / Site data room processes to an agreed programm quality and continuous improvement

9 2. PROCESS DESCRIPTION The single train crude and vacuum distillation units can process a wide variety of crude oils. Sweet and sour crude oils are processed in a block operation primarily dictated by bitumen production. The unit has sufficient metallurgy to process acidic crude oils and other challenging crude oils like CPC. The crude oils are fractionated into streams which are then further processed into finished products. The high vacuum unit recovers gas oils from the long atmospheric residue and the residue is either further processed in the visbreaker for heavy fuels production or routed to bitumen blending. The vacuum residue processed in the visbreaker is routed to either heavy fuel oil or used to produce the harder grades of bitumen. The visbreaker allows the Refinery to reduce the production of heavy fuel oil and broaden the types of crude oils that can be used to produce bitumen. All Naphthas from the atmospheric distillation unit are desulphurised in the 27,000 bpd Naphtha treater. After fractionation, the light virgin Naphthta (LVN) is either blended to finished Gasoline or sold as petrochemical feedstock. The Heavy Naphtha fraction is further processed in the Catalytic Reforming unit (Platformer). The Reformate product is either blended into finished Gasoline or sold as petrochemical feedstock, typically for aromatics production. A single medium pressure distillate hyrodesulphuriser treats Kerosene, straight-run and cracked Gas Oils (from catalytic and thermal cracking units as well as visbreaker) to produce finished Diesel and Heating Oils. The Refinery has a unique flexibility in the conversion of gas oils with both a fluid catalytic crackig unit (FCC) as well as thermal cracking unit (integrated with the residue with the residue visbreaker). The FCC processes straight-run and vacuum gas oils to produce LPG, gasoline, distillates and a small amount of heavy fuel oil. In the current configuration, the FCC processes some vacuum residue from sweet crude oils and the revamp in 2010 expanded this capability. The thermal cracker processes primarily vacuum gas oils producing mostly distillates; unconverted material is routed to the visbreaker for further processing.
