Feasibility study of Waste Heat Utilization in ...
50,40 € *
ggf. zzgl. Versand

Waste heat utilization is well known for saving energy, cost and environment, but its practical implementation is not common especially in developing countries. Heat is produced as a result of energy usage. Overall efficiency of the process improves if waste heat is utilized before it is lost to environment. This book discusses the waste heat recovery system designed for a Glass Factory in Pakistan. In order to extract heat from flue gases, the dew point temperature is first calculated in order to have a lower limit of flue gas exit. The exergy of flue gases is then determined based on this limiting value. This available energy is to be used to preheat the furnace oil during the low ambient temperature season. In order to impart this energy to the furnace oil, two heat exchangers have been designed. The first heat exchanger transfers heat from the flue gases to an intermediate heat transfer medium. The second heat exchanger is designed to transfer heat from to the furnace oil. An insulated piping network is also designed in order to meet the purpose. Two pumps are selected in order to pump these fluids. The expected payback period of investment is also calculated.

Inert Gas

An inert gas is a non-reactive gas used during chemical synthesis, chemical analysis, or preservation of reactive materials. Inert gases are selected for specific settings for which they are functionally inert since the cost of the gas and the cost of purifying the gas are usually a consideration. Nitrogen and argon are the most common inert gases for use in in chemistry and archival settings. Unlike noble gases, inert gas is not necessarily elemental and is often a compound gas. Like the noble gases the tendency for non-reactivity is due to the valence, the outermost electron shell, being complete in all the inert gases. This is a tendency, not a rule, as noble gases and other "inert" gases can react to form compounds. In marine applications, inert gas refers to gases with a low content of oxygen that are used to fill void spaces in and around tanks for explosion protection. There are two types of inert gas which are either based on nitrogen or on flue gas

The Production of Biodiesel from Microalgae: Te...
56,50 € *
ggf. zzgl. Versand

The production of biofuels from microalgae, especially biodiesel, has become a topic of great interest in recent years. All the steps in the process must also be very low cost. However, many of the published papers do not consider the question of scale up and the feasibility of the various processes to be operated at the very large scale required if algal biofuels are to make a meaningful contribution to renewable fuels. Recently, technological advancements have made microalgae biodiesel closer to being economically feasible through increased efficiency of the cultivation, harvesting, pre- treatment, lipid extraction, and transesterification subsystems. The metabolism of microalgae can be favourably manipulated to increase lipid productivity through environmental stressors, and ''green'' techniques such as using flue gas as a carbon source and wastewater as a media replacement. This paper discusses the unit processes required for algal biofuels production (i.e., growing the algae, and their techno-economic feasibility.

Global warming, caused by rising greenhouse gases (GHG) in the troposphere (or enhanced greenhouse effect), has received increasing attention in recent years. The greenhouse effect is a natural process in which solar energy is transmitted through the atmosphere warming the earth. The infra-red radiation reflected from the earth surface is trapped by GHG in our atmosphere thereby causing a warming effect on the earth and making it able to maintain life. Global warming occurs when these GHG increase beyond natural levels resulting in increasing temperatures. A relatively inexpensive process for CO2 capture from flue gas is needed to make reduction of CO2 emissions an economically viable global goal. CO2 was chemically adsorbed and the CO2 uptake occurred at a temperature of 60°C and the entrapped CO2 was released at 150°C to shift the reaction in the reverse direction. When compared to other processes such as the conventional amine process this work provides an efficient, low utility cost and energy-conservative effect and may be applicable to existing fossil fuel combustion sources.
