Interpretation Of Experts: Condensate Characteristics And Leakage Into The Sea After The Impact

- Jan 10, 2018-




On January 6, at about 20 o'clock on January 6, the "Sanchi" round of Panamax tankers collided with the "Changfeng Crystal" round of Hong Kong-made bulk carriers (shipyards trading in the shipyards) about 160 nautical miles to the east of the mouth of the Yangtze River, The whole ship fire. "Sanjay" contains about 136,000 tons of condensate on wheels and "Changfeng Crystal" carries 64,000 tons of grain on wheels. After the accident, some media expressed concern about whether the accident would have a serious impact on the marine ecological environment in the East China Sea. In response, Zhao Ruoxiang, a senior engineer of the Yantai Oil Spill Emergency Technical Center of Yantai Maritime Bureau, pointed out the characteristics of condensate and its leakage into the sea The impact is interpreted.


According to Zhao Ru box introduction, condensate is condensate gas field or gas condensate from natural gas condensate out of the liquid phase component, also known as natural gasoline, the main component is a mixture of C5 to C11 hydrocarbons and contains a small amount of hydrocarbons and sulfur dioxide and Polysulfide and other impurities. Condensate at room temperature as a light brown liquid, density, viscosity lower. Its high volatility (similar to gasoline), the higher the temperature the more volatile, so the condensate into the water will quickly evaporate, residual water rarely, but in the air filled with fire easily lead to fire and explosion accidents. Condensed oil contains toxic hydrogen sulfide and mercaptan and other components, volatile will cause some pollution to the atmosphere, while the decomposition of combustion will generate nitric oxide, nitrogen dioxide, nitrogen oxides, sulfur oxides and other toxic smoke, Through inhalation, skin invasion, etc. will cause poisoning harm to the human body.


According to Yantai Oil Spill Emergency Technology Center simulation, condensate leak 5 hours later, the remaining oil content of less than 1% of the sea.


At present, the "Sanjay" round is still burning and no large-scale oil spills have been found on the sea. The 13 search and rescue vessels of "Sea Patrol 01" organized by on-site command ship (shipyard trading) Search within 900 square nautical miles and closely monitor the status of "Sanjay"
