ENVIRONMENTAL PROTECTION

18 Analysis on the Operation Status of Oil Vapor Recovery Unit for Gas Station.Liu Dong.

Abstract: In Beijing, the oil vapor recovery units for post-treatment of oil vapor discharged from gas stations have been installed for many years. The recovery efficiency of oil vapor is low and the failure rate is increasing. Based on the calculation of the environmental benefit of the post-treatment device, the suggestion is proposed that under the condition of the strict control of the gas-liquid ratio, the equipment can be cancelled.

Key words: gas station, oil vapor recovery, post-treatment device, operation, analysis.

QUANTITY AND QUALITY MANAGEMENT

22 Study on the Relation of Lubricity with Sulfur Content and Composition of Diesel Fraction.Liu Xinlu, Zhang Fengquan, Yang Yong, Dong Fang.

Abstract: The lubricity, density, viscosity and aromatics content of diesel fractions produced from different processes were analyzed. The results showed that, in the absence of additives, the diesel fraction with higher sulfur content showed better lubricity; the density was negatively correlated with the wear scar diameter; the kinematic viscosity and the wear scar diameter did not show a good correspondence; the lubricity of diesel fraction was a comprehensive result which was influenced by the polycyclic aromatics content, density and so on, and was not affected by the monocyclic aromatics content.

Key words: diesel fraction, lubricity, sulfur content, density, viscosity, relationship.

31 Problems in Formulating Emergency Plan of Inland Aquatic Gas Station (Barges) and Solutions.Mao Xingzhi.

Abstract: Taking an inland aquatic gas station in Jiangsu section of the Yangtze River as an example, the emergency plan is compared with that of onshore gas station. The problems in the emergency plan of inland aquatic gas station are pointed out, i.e. the site scene classification system is not detailed, the risk analysis is not sufficient, the emergency work division of responsibilities is different with the actual situation, the severity of the accident are not fully considered for emergency response procedures, and the matters needing attention are not related to the aquatic operation. The corresponding countermeasures are put forward: the emergency plan should be formulated on basis of the functional zoning and special operation of aquatic gas station; the risk analysis should be combined with the surrounding environment and the qualitative and quantitative accident model; the responsibility of emergency should be strictly implemented according to the duties of gas station staff; the emergency measures to be classified according to the severity of accidents; the characteristics of aquatic operations should be reflected in the matters needing attention.
