挥发性气体(VOC)热氧化处理为高耗能过程,需利用热回收或热再生作为节能手段.作者以热回收因子(heat recovery factor,HRF)、设备价格因子(equipment cost factor,ECF)两个独立参数,分别分析了能源效率及投资回收,讨论了挥发性气体(VOC)热氧化处理设计的重要影响因子.利用能源回收成本比(equipment cost against heat recovery),以一工业实例,分析了不同设计情境下系统的比较优势.复热型和再生型热氧化系统也在文中作了比较,复热型有较低的ECF,而再热型则有较高之HRF;然而,当以能源回收成本作比较时,热再生型在使用周期较长时,具有经济方面的优势.所呈现的分析模型亦可用于类似的环保系统. 相似文献

Summary The glutamine levels in digestive gland, foot and body fluids of normal, starved and aestivatedPila globosa were estimated. Glutamine content was decreased during starvation and aestivation. The percent decrease was more during aestivation than starvation. The decrease may be due to low glutamine-synthetase activity or increased utilization for uric acid synthesis. This may have an adaptive value during aestivation and starvation.Acknowledgments. C. Sree Ramulu Chetty and P. Aruna are thankful to CSIR for the award of Junior fellowships, during the tenure of which the work has been done. 相似文献

Summary A metal analysis of bovine hepatic gluconolactonase indicates the presence of at least 1 atom of tightly bound zinc per enzyme subunit in this hexameric protein. Other divalent metals are present in lesser quantities and are subject to removal by EDTA. Activation energies for the manganese and magnesium catalyzed reactions are 5.3 and 11.0 kcal/mole, respectively. 相似文献
