鄱阳湖水质状况分析与评价

鄱阳湖是我国最大的淡水湖,对其水质的监测和分析有着重要意义。本文通过1980～1988年水质监测资料的搜集整理,分析了鄱阳湖水质的时空分布规律,并作出了比较全面的评价。评价结果表明,鄱阳湖已受到轻度污染,但其水质总体状况尚属良好,是全国淡水湖泊中最好的湖泊之一。     

浅谈化工装置灾害事故的处置

化工生产一般采用温控分离、氧化还原、催化裂解、压力聚合等工艺方法,而化工产品特别是中间产品一般都具有易燃、易爆、有毒、有害和腐蚀等特点.在化工生产的过程中可能发生的各类灾害事故已经成为各级政府和应急救援单位研究的重要课题.下面结合工作实践谈谈化工装置灾害事故的处置思路.

Life cycle analysis and choice of natural gas-based automotive alternative fuels in Chongqing Municipality,China

Road transport produces significant amounts of emissions by using crude oil as the primary energy source. A reduction of emissions can be achieved by implementing alternative fuel chains. The objective of this study is to carry out an economic, environmental and energy (EEE) life cycle study on natural gas-based automotive fuels with conventional gasoline in an abundant region of China. A set of indices of four fuels/vehicle systems on the basis of life cycle are assessed in terms of impact of EEE, in which natural gas produces compressed natural gas (CNG), methanol, dimethylether (DME) and Fischer Tropsch diesel (FTD). The study included fuel production, vehicle production, vehicle operation, infrastructure and vehicle end of life as a system for each fuel/vehicle system. A generic gasoline fueled car is used as a baseline. Data have been reviewed and modified based on the best knowledge available to Chongqing local sources. Results indicated that when we could not change electric and hydrogen fuel cell vehicles into commercial vehicles on a large scale, direct use of CNG in a dedicated or bi-fuel vehicle is an economical choice for the region which is most energy efficient and more environmental friendly. The study can be used to support decisions on how natural gas resources can best be utilized as a fuel/energy resource for automobiles, and what issues need to be resolved in Chongqing. The models and approaches for this study can be applied to other regions of China as long as all the assumptions are well defined and modified to find a substitute automotive energy source and establish an energy policy in a specific region.
