Abstract:

Abstract Environmental concern and tighter public regulations have created new pressures to reduce effluent loading from kraft pulp bleaching during the past decades. This trend has forced both pulp mills and the related engineering industries to develop and optimise equipment for the pulping processes which fulfils these demands. New pulp washers and washing systems connected with the introduction of new oxygen-based reagents have in particular provided considerably improved tools for reusing process water and thereby essentially reducing effluent discharge or even allowing the implementation

Abstract:

The productivity of most gas condensate wells is reduced significantly due to condensate banking when the bottom hole pressure falls below the dew point. The liquid drop-out in these very high rate gas wells may lead to low recovery problems. The most important parameter for determining condensate well productivity is the effective gas permeability in the near wellbore region, where very high velocities can occur. An understanding of the characteristics of the high-velocity gas-condensate flow and relative permeability data is necessary for accurate forecast of well productivity. In order to

Abstract:

The kiln drying of wood produces huge amounts of vapour. The vapour is released to the environment when the process purges some of the saturated hot air. The main environmental issue regarding the use of kiln drying process are the release of the water vapour which contains organic contaminants. Some of them are hazardous to human health. In addition, there are some wood particles which may released with the water vapour purging process. In this research, the vapour is condensed and analysed for its organic contaminants and their biodegradability. The result showed that the dominant contamina

Det här projektet har varit på uppdrag av Kalmar Energi AB och har utförts på kraftvärmeanläggningen Moskogen. Projektet syftade till att undersöka om återvinning av rökgaskondensat till spädvatten var möjlig och ekonomiskt försvarbart. Denna åtgärd skulle potentiellt kunna minska anläggningens råvattenkonsumtion och det skulle leda till en ekonomisk besparing. Åtgärden skulle även bidra till att anläggningen blev mer självförsörjande och mindre känslig vid störningar på det lokala råvattennätet.

Considerable ongoing risk of condenser in-leakage exists at Otahuhu B (OTB) Power Station. The condenser cooling water used at OTB station is corrosive brackish water with exceedingly high sodium and chloride concentrations.

In the event of condenser in-leakage, the salt contaminants in the cooling water will directly enter the Heat Recovery Steam Generator (HRSG) with the potential for significant and costly damage resulting in a long plant outage.

Abstract:

Many gas wells suffer a loss in productivity due to liquid accumulation in the near wellbore region. This problem starts as the flowing bottom hole pressure drops below the dew point in wells producing from gas condensate reservoirs. Chemical stimulation may be used as a remedy, by altering the wettability to non-liquid wetting. Successful treatments decrease liquid trapping, increase fluids mobility, and improve the well’s deliverability. The main focus in this research was to develop an effective chemical treatment to mitigate liquid blocking in gas wells producing from carbonate reservoirs.

Several methods such as gas recycling, hydraulic fracturing and solvent injection have been tried to restore gas production rates after a decline in well productivity owing to condensate and/or water blocking. These methods of well stimulation offer only temporary productivity restoration and cannot always be used for a variety of reasons.

博士<br>國立中山大學<br>材料與光電科學學系研究所<br>97<br>This thesis is about the synthesis and characterization (electron microscopy and spectroscopy) of chromium oxide condensates prepared by a dynamic process of pulsed laser ablation (PLA) or pulsed laser ablation in liquid (PLAL) regarding the composition, size, shape, structure and internal stress of the condensates under the influence of laser parameters and dopant. Firstly, dense chromium oxide nanocondensates dissolved with ca. 4 atomic % Si, according to energy dispersive X-ray analysis, were fabricated by PLA on a clamped Cr/Si target in air purged wi

碩士<br>國立聯合大學<br>環境與安全衛生工程學系碩士班<br>100<br>The research of water purification sludge (WPS) reuse has been highly focused in the past period. Hence, reusing the WPS is becoming an important topic, and recovering alum from WPS is one of the many practical alternatives. Most previous research efforts have been conducted on studying the amphoteric characteristic of aluminum hydroxide for investigating the optimum pH range to dissolve the Al(III) species from WPS. In order to think of the cost and safety, the addition of acid and base should not be excessive, but cause the dissolution of the aluminu

碩士<br>逢甲大學<br>土木工程學系<br>106<br>It is certain that cities all over the world will face water resource shortages in the future. Although Taiwan belongs to a region of high temperatures and heavy precipitation, due to its terrain and rainfall characteristics, it remains a country severely lacking in water. Therefore, how to effectively utilize limited water resources as well as discover more are challenges which must be overcome. Conventional methods of direct water utilization such as constructing water reservoirs, diverting water from rivers, drawing groundwater, desalinating sea water as well

博士<br>國立交通大學<br>環境工程系所<br>93<br>Semiconductor industry has been a central figure to the economic growth in Taiwan, especially for the fabrication sector of integrated circuit (IC) that has evolved into world-leading status. The fabrication technology advances so far that the feature size (or critical line-width) of IC devices has now broken the 0.1 �慆 barrier and into the nano-scale age. This progress discloses that the traditional definition of a “cleanroom” environment may become increasingly inadequate because prevention of particulate contamination may no longer be a critical issue. As the

碩士<br>國立臺北科技大學<br>能源與冷凍空調工程系碩士班<br>101<br>The airborne molecular contamination (AMC) control has become an important issue since smaller and smaller integrated circuit (IC) linewidth is used in semiconductor products. During the process of wafer storage and transportation in front opening unified pods (FOUP), any AMC may pollute the wafer and decrease the defect-free rate. The AMC inside a FOUP might be reminder from the previous manufacturing process or the cross-contamination between wafers. Therefore, if the real-time AMC concentration inside a FOUP can be monitored to evaluate the cleanlin
