摘要:

AbstractA new and effective method has been developed for the treatment of VOC's, PCB's and other toxic organics. Direct UV photolysis of organics is achieved with this new method with the use of high intensity ultraviolet light of a broad UV spectrum. Standard and novel UV flashlamps can be used for generation of this broad UV spectrum. The pulsing nature of such spectrum helps to increase the efficiency of destruction of toxics. The final products of this destruction process are non‐toxic simple compounds. The energy efficiency of this new process exceeds that of traditional UV aided processes with medium pressure mercury lamps. This article reviews the Direct UV Photolysis Process, gives experimental results, and provides recommendations for applications in the treatment of groundwater, wastewater, contaminated air and soi

摘要:

AbstractWhile considerable global warming uncertainties remain, limiting the emission of the greenhouse gas, CO2at minimum cost is a growing social concern. An approach suggested is to genearte electricity by processes that facilitate capture of the CO2, and then to compress and inject it into suitable underground formations. By using formations containing uneconomical deposits of energy sources such as oil, gas, Fe+ +, coal, etc., underground bioconversion of the CO2to recoverable fuel forms may prove possible.

摘要:

AbstractThe role of aggregates and their characteristics on bioremediation in soil has received very little attention. In this investigation, the contaminated aggregates bioremediation (CAB) model has been developed and simulated to analyze the bioremediation of soil and water in the aggregates. The model equations consist of a system of three non‐linear partial differential equations. Dimensional analysis of the equations has been performed. Sensitivity analysis conducted by numerically solving them has demonstrated the effects of aggregate radius, partition coefficient, and initial contaminant concentration on the time and mechanism of remediation. The rates of diffusion of substrate and oxygen, and the biodegradation‐rate have been found to be the controlling mechanisms for remediation in the aggrega

摘要:

AbstractA research institute, due to its routine use of chemicals, equipment, and energy in research activities, is without exception a waste generator. The Development Center for Biotechnology in Taiwan, the Republic of China, has therfore taken the initiative in constructing an up‐to‐date plant for the treatment of liquid wastes in consideration of the public concerns and environmental impact. From the start operation of the wastewater treatment plant in July, 1989, the effuent quality has been maintained, at one hundred percent of the time, lower than the effluent discharge limits. The gained operation experiences as well as qualitative and quantitative aspects of liquid waste outputs from the biotechnology research institute are presen

摘要:

AbstractThe principal emission source of nitrogen oxides (NOx) and carbon monoxide (CO) from ethylene plants is the pyrolysis furnace. This paper addresses NOx/CO emissions and controls for gas fired pyrolysis furnaces. Typical NOxand CO generation rates for furnaces are quantified. The impact of fuel coposition on NOxgeneration is discussed. Commercially available and emerging control technologies are reviewed. The relative costs of these controls are compared. Case‐by‐case considerations will dictate the selection of the control technology required to comply with the environmental demands of the specific s
