Reducing the Impact on Water

• Kerosene Merox Project (Completed in October 2001): The most significant pollution reduction was accomplished through the implementation of the Merox process in which sulphur compounds are converted to disulphides, eliminating discharges of Lead Sulphide (PbS) to the effluent system. Cost: Million US$ 29
  
  
• VBU PbS Treating (Completed in 2003): Through innovative thinking another PbS plant has now ceased to operate and a process alternative has been implemented to remove the sulphur of the Visbroken Naphtha by treating it at the existing Unfiner/Platformer Plant.
  
  
• Unleaded Gasoline Project (Completed in July 2000): It has eliminated the use of Tetraethyl Lead (TEL) and consequently removed the contamination by organic lead of tank water bottoms, and hence refinery effluent system. The project also eliminated the lead emissions to the environment in line with global leaded gasoline phase out, and eventually Bahrain was declared as unleaded in September 2000. Cost: Million US$ 6.9
  
  
• Rerouting of Sitra Tank Farm Wastewater (Completed in 2002): This project enabled the transfer of waste water streams resulted from Sitra Tanks Farm operations back to the main Refinery effluent treatment system, which allowed better treatment of wastewater. Cost: Million US$ 1.6
  A similar project to pipe in the effluent from Marketing Terminal to Sitra Tanks was developed and completed in August 2003. Cost: US$ 150,000
  
  
• Refinery Biological Wastewater Treatment (Active Project): A project underway to identify opportunities for wastewater minimization and for the design of a new tertiary treatment facility the purpose of which is to reduce the dissolved solid pollutants like sulphide, phenol and ammonical nitrogen in order to meet the relevant national environmental legislations.
  
  
• Sewage Treatment Plant (Active Project): A sewage treatment facility at the Refinery is currently being progressed to ensure compliance with the relevant national regulations.
