Fuel distribution system

Other Energy Systems. Chemical plants usually require cooling water, compressed air, and fuel distribution systems. Sometimes also included are refrigeration, pressurized hot water, or specialized heat-transfer fluids such as Therrninol Hquid or condensing vapor. Each of these systems serves the process and reflabiUty is the most important characteristic. Thus a project in any of them that achieves a 10% reduction in energy cost at the expense of a 1% loss of rehabihty loses money for the operation. 

If fuel cell technology were introduced on a large scale for automotive transportation, would you prefer a fuel distribution system in which gasoline fuel remains the major energy carrier but is reformed on-board to hydrogen or one in which hydrogen is provided at fuel stations Explain your choice.

Fuel specifications also serve a very valuable service as a means of standardizing fuel properties, which facilitates trade and commerce of that fuel. For example, if each producer were allowed to produce fuels that varied in properties, the chances of vehicle manufacturers producing vehicles with acceptable and uniform performance, driveability, and fuel efficiency would be next to impossible. The fuel distribution system is based on the concept of fuel fiingibility, i.e., the ability to trade fuels within a wide region without fear of problems due to variations in fuel properties. 

Even with rapid growth in hydrogen FCVs, they would not compete economically with gasoline and diesel fuels or with ICEs for a long time, and not even then unless new manufacturing systems are devised and fuel distribution systems are restructured. Each 2003 FCV cost upward of 1 million to hand build. The infrastructure to refuel these vehicles consists of only a couple dozen costly compressed or liquefied hydrogen fueling stations. 

Green diesel is produced by a refinery process that permits quality control of biofuel and the use of existing infrastructure and fuel distribution systems. 

Business executives expect growth of the wood-for-energy business to occur slowly. While the means exist to collect and convert wood into useful products, the lack of wood fuel distribution systems is perceived to be a major barrier to growth. A further concern of executives is the lack of assurances regarding the long-term availability of supplies.

The detection of thiols (RSH) is important in two main fields, biology and environment. Thiols (or mercaptans) are smelly molecules present in petroleum. However, thiols have adverse effects (corrosion) on fuel distribution systems so that processes have been developed to reduce their level in petroleum, using for example thiol oxidation processes. It is thus important to be able to control via sensing devices the levels of thiols in gasoUne. 

As a chemical intermediate and solvent, highly pure synthetic methanol has been an article of commerce for several decades its properties and distribution modes are familiar and well understood in this context. In the role of transportation fuel, however, considerations are so radically different that fuel methanol must be treated almost as a new product. This is so partly because the general public is exposed to contact when fueling vehicles and partly because engine combustion products and fuel distribution systems raise a host of new technological questions that have never been addressed by conventional chemical industry. 

Bacterial genera used in this study were isolated from a jet fuel distribution system using selective solid media. They were transferred later to fuel/water systems containing 50 ml of JP (sterilized by a membrane filtration, as a carbon source) and 250 ml of a simplified mineral medium by a previously reported method (de Mele et al., 1979). Identification of the bacterial strains was made by phase contrast microscopy. Gram staining, and selected biochemical tests.
