油气田在役管道高后果区识别与完整性评价方法

根据油气管道建设与管理的相关标准与规范或导则,针对目前油气田在役管道,明确了其高后果区识别的划分及其在不同标准中的差异以及识别的原则和时间间隔,分别介绍了在管道的相关数据采集的基础上开展地质灾害和第三方破坏造成的管道风险评价方法,管道内外腐蚀的直接评价以及包括剩余强度、剩余寿命和材料在内的管道适用性评价方法,同时给出了这些评价工作所涉及到的相关内容项,对油田管道的完整性管理具有重要的指导作用和应用价值。     

密封组合形式对结构密封性能影响研究

目的研究密封组合形式对结构密封性能的影响。方法开展密封性能试验,从密封形式、装配形式和涂覆形式的3种组合形式开展试验研究,找出结构密封性能影响因素,筛选密封最优组合形式。结果结构密封3种组成形式分别为有无贴合面的密封形式,干涉装配、湿装配形式,部分涂覆、全涂覆形式。开展2种应力水平下8种密封组合形式的密封性能试验,在保证密封工艺质量条件下,按照飞机结构和受载特点选取合理密封组合形式能有效提高结构密封性能。结论在飞机应力较高、不常拆的密封部位应选择贴合面密封、干涉装配、部分涂覆的密封组合形式,在飞机结构设计要求间隙装配、常拆卸的密封部位选择贴合面密封、湿装配、部分涂覆的密封组合形式。     

Effect of Humic Acid on the Bioavailability of γ-Hexachlorocyclohexane in Marsilea Minuta (L.)

Effect of various concentrations of humic acid (0.2 to 1%) on thebioavailability of -HCH in vegetative clones of theaquatic fern Marsilea minuta was studied in a staticexperimental bioassay system on different photoperiods. Additionof humic acid showed the reduction in the bioavailability of-HCH in all the photoperiods (72 hr light to 144 hrlight) at the interval of 16 hr light (L) and 8 hr dark (D) inboth aerial and submerged portion as compared to controlindicating its protective role in toxicity.     

Application of a systemic approach to the study of pollution of the Tinto and Odiel rivers (Spain)

The province of Huelva in the SW of Spain presents high environmental contrasts: together with the great abundance of natural spaces, it shows the impacts of historical natural resources exploitation processes. In the Ria of Huelva, the effluents of the chemical industries must be added to the contaminating inputs of the Tinto and Odiel rivers, coming from the acid drainage of the mines located in the Iberian Pyrite Belt. This forced the Environmental Agency (AMA) to elaborate in 1987 an Effluent Remediation Plan in order to negate unacceptable environmental impacts. The application of a grey box systemic analysis to the AMD pollution, undergone by the Tinto and Odiel rivers has allowed to set a conclusive explanation of the sampling results observed for a period of 11 years, thus making available an overall view of the polluting process and, above all, an explanation of its partial aspects.

An integrated assessment model for cross-country pipelines

The cross-country petroleum pipelines are environmentally sensitive because they traverse through varied terrain covering crop fields, forests, rivers, populated areas, desert, hills and offshore. Any malfunction of these pipelines may cause devastating effect on the environment. Hence, the pipeline operators plan and design pipelines projects with sufficient consideration of environment and social aspects along with the technological alternatives. Traditionally, in project appraisal, optimum technical alternative is selected using financial analysis. Impact assessments (IA) are then carried out to justify the selection and subsequent statutory approval. However, the IAs often suggest alternative sites and/or alternate technology and implementation methodology, resulting in revision of entire technical and financial analysis. This study addresses the above issues by developing an integrated framework for project feasibility analysis with the application of analytic hierarchy process (AHP), a multiple attribute decision-making technique. The model considers technical analysis (TA), socioeconomic IA (SEIA) and environmental IA (EIA) in an integrated framework to select the best project from a few alternative feasible projects. Subsequent financial analysis then justifies the selection. The entire methodology has been explained here through a case application on cross-country petroleum pipeline project in India.
