  2. General Overview • Start Up: 1970 • Shut Down: July 2007 • Capacity: 15 kmta (starting with benzene) • Technology: Benzene oxidation process • Upgrades: € 8MM invested in 2000

  3. General Overview • Access to road and rail service with a harbor less than 100 km away • Large quantity of new spare parts • Process equipment was cleaned with water and is currently being kept under a nitrogen pad • Process area footprint is 100m by 50m and the highest structure is about 35m tall • There are no other chemical facilities located in the immediate area

  4. General Overview Utilities Consumed: Raw Materials: • Electricity • Natural Gas • Water • Steam (produced from the exothermic reaction) • Benzene or Butane • Air • Vanadium Catalyst Products Produced: Consumption Figures: • Maleic Anhydride • 1235kWh of electricity • 22.5kw of LNG • 9 tons of steam • 5.7m3 of demineralized water • 9.8kg of Nitrogen Production Figures: • 11.9 tons of steam • 750 kWh through a thermic fluid

  5. Process Description Summary of Operations • The plant produces 15 kmta of maleic anhydride starting with benzene due to a partnership with a neighboring coal processing plant which produced a benzols stream. • This process of extracting benzols from the benzols stream has been removed from the site. • The process currently uses benzene reacted with oxygen over a vandium catalyst to produce maleic anhydride • Maleic anhydride is a solid at room temperature, but the plant maintains the process temperature above the 40°C melting point to keep the product fluid. This process is very efficient regarding benzene conversion with only 2 ppm of residual benzene remaining (specification is 5 ppm). • The reaction is highly exothermic, producing 60 kmta of 18 bar steam. • The Gillendorf reactor runs at 4 bar pressure and is basically a large shell and tube exchanger with over 1,000 tubes packed with the vanadium catalyst.

  6. Process Description Summary of Operations • The oxygen is obtained from air, which is compressed to the reactor pressure of 4 bar with a large 40,000 m3/hr Brown Boveri-Sulzer centrifugal compressor with a 1,250 kw electric drive. • The “100” section of the plant consists of the main reaction: oxidation of benzene. It also includes the condensation reaction and subsequent adsorption of the product into water with a packed tower. • The “200” section of the plant is dehydration utilizing a 32m2 Luwa wiped film evaporator. • The “300” section of the plant vacuum distills the crude Maleic Anhydride, removing residual impurities and residue. The vacuum is created by modern, liquid-ring vacuum pumps. • The control system for the plant is a relatively new Foxboro DCS system with flat screen monitors.

  7. Process Description Utilities • A natural gas-fired hot oil furnace using Marlotherm as the heat exchange fluid is used for much of the process heating. • The reactor is cooled with a molten salt system circulating 80 metric tons per hour of salt. • There is a demineralized water system used in the adsorption process. • The system produces a very high quality water product due to the requirements for process water in the plant. Environmental, Health & Safety • A stainless steel carbon bed vent adsorption system was installed in 2001 to remove all benzene and other hydrocarbons from the process vents. • The final vent goes to the atmosphere, with a gas chromatograph on the vent stack to detect any residual hydrocarbons.
