METHOD AND SYSTEM FOR TREATING CARGO VAPORS FROM CRUDE OIL AND PETROLEUM PRODUCTS TANKS TO PRODUCE ELECTRICITY

摘要

System and method for treating cargo vapors from crude oil and petroleum products tanks (2) to generate electrical power. The system and method comprising the steps: separating the cargo vapors into liquid volatile organic compounds (LVOC) and compressed surplus gas in a VOC recovery plant (1). Providing a gas turbine (6) having a compressor (7), a combustion chamber (8) and an expander (9). Feeding the compressed surplus gas to the combustion chamber (8). Feeding the liquid volatile organic compounds (LVOC) to the combustion chamber (8) as pilot fuel. Feeding air to the compressor (7) operated by the expander (9), where feeding the compressed air to the combustion chamber (8) is reduced proportionally to the feeding of the surplus gas, and combusting the compressed air, surplus gas and the liquid volatile organic compounds (LVOC) in the combustion chamber (8) and using the combustion for operating a generator (12) with the gas turbine (6) to generate electrical power.
