Bioenergy - II: Fuels and Chemicals from Renewable Resources

The need for a renewable ‘green’ chemistry is adamant because of the adverse effects of the increasing use of fossil fuels on our society, like global warming and the depletion of fossil fuel resources. Therefore, the use of ligno-cellulosic (woody) types of biomass as a renewable source for chemicals and energy is increasingly becoming important. Unfortunately, the heterogeneity of biomass presents a major obstacle to chemical utilization. The main constituents hemicellulose, cellulose and lignin are strongly interconnected by a variety of physico-chemical bonds that makes it difficult to extract individual chemicals in high yields. So an efficient and cost-effective fractionation …

Applying Technology Advancements To Improve Heat Exchanger Economic And Environmental Performance In Refinery Crude Preheat Trains, Himanshu Joshi, Fred Hoeve, Eric Van Der Zijden Jul 2007

Applying Technology Advancements To Improve Heat Exchanger Economic And Environmental Performance In Refinery Crude Preheat Trains, Himanshu Joshi, Fred Hoeve, Eric Van Der Zijden

Heat Exchanger Fouling and Cleaning VII

Fouling of heat exchangers in crude preheat trains is a major refinery operations business factor. It is realised that fouling cannot be completely eliminated, but considerable economic and environmental benefits are available with the proper application of improved technology in both the equipment and software asset management tools areas. This paper presents a technology update of refinery applications of a heat exchanger network analysis software to identify optimal crude preheat train cleaning.


Designing Two-Phase Flow Heat Exchangers For Mitigating Fouling, C.B. Panchal, Blazo Ljubicic Jul 2007

Designing Two-Phase Flow Heat Exchangers For Mitigating Fouling, C.B. Panchal, Blazo Ljubicic

Heat Exchanger Fouling and Cleaning VII

Significant progress has been made in understanding the underlying mechanisms of hydrocarbon fouling and characterizing the effects of physical and chemical parameters in single-phase flows. However, the interactive effects of two-phase flows and fouling mechanisms are poorly understood. Many of the industrial heat exchangers in refining and petrochemical processing operate under multiphase flow conditions with varying flow regimes. Fouling and localized corrosion are generally experienced due to maldistribution of vapor and liquid phases in such heat exchangers. This is because design methods are inadequate to determine localized process conditions that could induce severe fouling locally, which could also lead to …


Crystallization Fouling Behaviour Of Uranium Oxide And Alumnosilicate Scale In High Level Nuclear Waste Medium, Jonas Addai-Mensah, Jun Li, Bill Wilmarth Jul 2007

Crystallization Fouling Behaviour Of Uranium Oxide And Alumnosilicate Scale In High Level Nuclear Waste Medium, Jonas Addai-Mensah, Jun Li, Bill Wilmarth

Heat Exchanger Fouling and Cleaning VII

During high level nuclear waste (HLNW) liquor processing in evaporators operating in the temperature range 30 - 140 °C, dissolved silica, alumina, sodium hydroxide, uranium-235 and transuranic species (e.g. plutonium-238) invariably become concentrated. As the liquor evaporation proceeds, the sodium aluminosilicate (SAS) and radionuclides may exceed their solubility limits and co-precipitate, fouling the tubes and walls of the evaporator. If the fouling process is not effectively controlled or mitigated, radionuclide scale accumulation exceeding the critical mass necessary for self-sustaining nuclear fission reaction may proceed at an alarming rate, posing a serious criticality concern. To probe the mechanisms underpinning uranium oxide-sodium …


Precipitation And Fouling In Heavy Oil–Diluent Blends, E Hong, A. Paul Watkinson Jul 2007

Precipitation And Fouling In Heavy Oil–Diluent Blends, E Hong, A. Paul Watkinson

Heat Exchanger Fouling and Cleaning VII

Heavy oil fractions rich in asphaltenes were mixed with diluents containing from 0.6-25% aromatics, and the resulting blends subjected to batch precipitation experiments at 85°C, and thermal fouling tests at surface temperatures in the range 230-310ºC. Deposit compositions were determined, and are compared with suspended asphaltene composition. When the heavy oils were blended with the most aromatic diluents, precipitation and fouling were negligible. As the aromaticity of the diluents was decreased, the extent of asphaltene precipitation and the fouling rates increased. The solubility parameter of the blends, δmix, and the flocculation solubility parameter for asphaltenes, δf , were determined from …


Costs Due To Utility Fouling In China, Xu Zhi-Ming, Zhang Zhong-Bin, Yang Shan-Rang Jul 2007

Costs Due To Utility Fouling In China, Xu Zhi-Ming, Zhang Zhong-Bin, Yang Shan-Rang

Heat Exchanger Fouling and Cleaning VII

This paper puts forward a method for evaluating the fouling costs of boilers and turbines in power plants. Furthermore, the Huaneng Dalian Power Plant and Changshan Power Plant are taken as examples for analyzing the costs of fouling. Based on data of on-site measurements in the above Power Plants, the costs due to fouling such as excess surface area, product loss, operating maintenance and increase of product costs are calculated. Results show that the total economical loss due to boiler and turbine fouling in China reaches 4.68 billion dollars, which covers is about 0.169% GDP of China in 2006.
