Strategic planning optimization for natural gas to liquid transportation fuel (GTL) systems

A strategic planning optimization model is proposed for a network of natural gas to liquids (GTL) systems, and it is solved using a rolling horizon strategy. The model formulation determines the strategic and tactical decisions of the GTL supply chain over a long time horizon. The decisions to build new GTL refineries may be made over the span of 30 years and their operations cover the span of 60 years. Multiple capacities of GTL refineries (i.e., 1, 5, 10, 50, and 200 thousand barrels per day) that produce gasoline, diesel, and kerosene commensurate to the United States demand ratio may exist in the network. The parameter inputs include the locations, availabilities, and prices of natural gas in the United States discretized by county, the delivery locations of fuel products, and the transportation costs of every input and output of the refinery, defined for each time period. Formulated as a large-scale mixed-integer linear optimization (MILP) model, the problem is solved using a rolling horizon strategy for tractability. Case studies on the state of Pennsylvania are presented for different planning schemes and their impact on the economic performance of the GTL network is discussed.

Reviews of clean coal conversion technology in China:Situations & challenges

It is important to develop the advanced coal to chemicals industry (ACCI) against a backdrop of coal-based energy structures,excessive imported oil and natural gas,and strict environmental con-straints in China.In this study,the technology and industry of China's ACCI are reviewed to explain the effect of using coal to replace oil and natural gas,and the corresponding resource and environmental burdens that this will create.Development trends in technology and industry are also proposed to explore future scenarios.The review shows that although excellent progress has been made on an indus-trial scale,demonstrative level,and in terms of technology and equipment,the lack of strategic under-standing,severe external constraints,partly underdeveloped technologies,and weak foundations must be immediately addressed.Therefore,it is necessary to clarify the importance that the ACCI has on the energy revolution and energy system.Based on technological innovation,a variety of external factors should be considered as a whole with emphasis on filling the knowledge gap of theoretical foundations and industry standards to support high-quality development for ACCI.     

Retro-analysis of liquid bio-ethanol and bio-diesel in New Zealand

This paper uses a new approach of retro-analysis. Typically policy is informed by forward-looking analysis of potential for alternative energy technologies. But historical knowledge of energy and processing requirements and greenhouse effects is more reliable for engineering evaluation of biofuel production systems. This study calculates energy inputs and greenhouse gas emissions for the most efficient biomass feedstocks in New Zealand if the policy had been implemented to maximize liquid biofuel production in the year 2004/2005. The study uses existing processing technologies and agricultural statistics. Bioethanol production is calculated from putrescible wastes and starch crops, and biodiesel production from rapeseed, tallow, wood and waste paper. Each production system is further evaluated using measures of land use, energy input, crop production related to the energy product, plus relative measures of efficiency and renewability. The research findings are that maximum biofuel production in 2004/2005 would have provided only a few per cent of demand, and would not have reduced dependence on foreign imported oil or exposure to fuel price rise. Finally, we conclude that demand management and efficiency are more effective means of meeting policy objectives.

挑战、成因与中国电信业的战略重组(上)

目前我国电信行业依然面临着多重挑战,主要表现在重复建设、规模经济效益弱化、市场缺乏有效调解机制、产业链布局不合理等。其成因主要是产业组织结构调整不到位、产权结构和内部治理机制不合理,以及人力资产的路径依赖等。新一轮电信改革有三大目标,其经济目标一是提高对国民经济贡献率,二是对产业链及旁侧产业的拉动。政治目标是必须从根本上体现全体国民的总体福利,主要通过资费水平的下调和服务质量的提高来体现。因此,如何通过新的改革,控制或降低电信行业的垄断租金,使其转化为消费者剩余,也应成为新一轮改革的重要目标。社会目标是更好地处理好普遍服务问题。     

Twitter information for contributing to the strategic digital city: Towards citizens as co-managers

Actions towards an effective city management require a focus on citizens, and it is a role of local governments to search for ways to provide their participation in the decision-making process. Among other information technology resources, local governments use social platforms thus facing the challenge of extracting and classifying information for strategic use. The objective of this study is to analyze Twitter information to contribute to the strategic digital city. The research methodology used was a case study of a Brazilian city. Twitter was analyzed, and the information assessed according to its characteristics, source, nature, quality, intelligence and organizational level. Results reveal Twitter allows communication, rudiments of public services and exchange and sharing information on municipal themes inherent to strategic digital cities. Information has quality and intelligence to serve the strategic level of government. The conclusion confirms that Twitter enhances transparency and strengthens bonds between local government and citizens.     

Assessing the natural ventilation cooling potential of office buildings in different climate zones in China

This paper presents an investigation of the natural ventilation cooling potential (NVCP) of office buildings in the five generally recognised climate zones in China using the Thermal Resistance Ventilation (TRV) model, which is a simplified, coupled, thermal and airflow model. The acceptable operative temperature for naturally conditioned space supplied by the ASHARE Standard 55-2004 has been used for the comfort temperature setting. Dynamic simulations for a typical office room in the five representative cities, which are Harbin, Beijing, Shanghai, Kunming and Guangzhou, have been carried out. The study demonstrates that the NVCP depends on the multiple impacts of climate, the building's thermal characteristics, internal gains, ventilation profiles and regimes. The work shows how the simplified method can be used to generate detailed, indoor, operative temperature data based on the various building conditions and control profiles which are used to investigate the NVCP at the strategic design stage. The simulation results presented in this paper can be used as a reference guideline for natural ventilation design in China.
