FLUE GAS DESULFURIZATION: COST AND FUNCTIONAL ANALYSIS OF LARGE - SCALE AND PROVEN PLANTS by Jean Tilly

Submitted to the Department of Chemical Engineering

on May 6, 1983 in partial fullfillment of the requirements for the degree of Master of Science in Technology and Policy

ABSTRACT

Flue Gas Desulfurization is a method of controlling the emission of sulfurs, which causes the acid rain. The following study is based on 26 utilities which burn coal, have a generating capacity of at least 50 Megawatts (MW) and whose Flue Gas Desulfurization devices have been operating for at least 5 years. An analysis is made of the capital and annual costs of these systems using a comparison of four main processes: lime, limestone, dual alkali and sodium carbonate scrubbing. The functional analysis, based on operability, allows a readjustment of the annual costs and a determination of the main reasons for failure. Finally four detailed case studies are analyzed and show the evolution of cost and operability along the years.

...Basic Processes SCI/230 January 30, 2012 Reproduction Germs reproduce asexually by using a method called binary fission in the prokaryotic cells and in mitosis. Germs split into two different creatures within the colony each cell exist apart from the other. Grasshoppers reproduce by copulating end to end and insert its aedeagus into the ovipositor to deliver his sperm. They reproduce by laying eggs, which are fertilized within the female grasshopper. The eggs contain a yoke for nourishment in the embryo each egg is covered by a shell that has terminal pores giving the sperm access to the eggs for fertilization. The male and female grasshoppers do not care for the eggs. Some fish reproduce by laying eggs and some fish reproduce by live bearing depending on the species. Some fish have male and female sex organ to reproduce without physical contact. Most fish lay eggs so the male fish can fertilize if she accepts the male. The eggs are fertilized by ejaculating their sperm at the eggs. Bears reproduce by physical contact the male just like humans. The male bear copulates inside the female fertilizing her egg, which develops into an embryo then into a fetus. The fetus is covered with membranes and fluid. According to Pruitt and Underwood (2006), “If egg and sperm each donate an equal number of chromosomes to the new embryo, then in the absence of other mechanisms, the chromosome number of each succeeding generation would exactly double.” The fact...

An organism is defined as an individual animal, plant or single-celled life form. Therefore the cell is considered the smallest unit of life competent of a self-sufficient existence. There are seven things that all living organisms from bacteria to plants to animals all have in common and whether something is living or not is usually compared to the seven life processes. These processes are movement, reproduction, sensitivity, growth, respiration, excretion and nutrition. The acronym ‘MRS GREN’ will be used when discussing the processes of life movement All living things move to some kind of degree and this is the most apparent within the animal kingdom. Animals are able to physically move themselves from one place to another; humans will usually use their muscles in order to be able to move where as other animals may have to hop, crawl, swim or fly. Movement is very important for gathering sustenance...

Welding Processes

...rods. The Swede Oskar Kjellberg made an important advance when he developed and patented the coated electrode. The welding result was amazing and formed the foundation of the ESAB welding company. Figure 1. I Principle of Manual Metal Arc ( M M ) welding. Another early method of welding which was also developed at that time was gas welding. The use of acetylene and oxygen made it possible to produce a comparatively high flame temperature, 3100°C, which is higher than that of other hydrocarbon based gas. The intensity of all these heat sources enables heat to be generated in, or applied to, the workpiece quicker than it is conducted away into the surrounding metal. Consequently it is possible to generate a molten pool, which solidifies to form the unifying bond between the parts being joined. Figure 1.2 Submerged arc welding. © 2003, Woodhead Publishing Ltd WELDING PROCESSES HANDBOOK Later, in the 1930s, new methods were developed. Up until then, all metal-arc welding had been carried out manually. Attempts were made to automate the process using a continuous wire. The most successful process was submerged arc welding (SAW) where the arc is "submerged" in a blanket of granular fusible flux. During the Second World War the aircraft industry required a new method for the welding of magnesium and aluminium. In 1940 experiments began in the USA with the shielding of the arc by inert gases. By using an electrode of tungsten, the arc could be struck without melting the......

Processes

...Processes for Students with Learning Disabilities Many college students have different processes for many different things. We are going to focus on the processes that students with learning disabilities deal with. Just a few of these processes have to do with oral language, study skills, and social skills that they may have to cope with. One process that these students have to go through is the process of oral language. Students with learning disabilities might have trouble with spoken languages. In order to get through this difficulty, they would need a process to follow. For example, one student might overcome this diversity by taking on the challenge of speaking with someone for help. This can also be very difficult for this particular person. Another thing that might need assisting by a process would be expressing their individual ideas. They could do this very thing by first thinking of their idea, they then might take their surroundings into consideration. By this I mean that they will feel more comfortable to express their ideas if their surroundings are gentle and calm. One more thing that may require a process involving oral language would be grammar. Grammar is probably one of the most difficult things to focus on if a learning disability is present. They can go about this problem by first talking it over with someone. After that, they can get a little practice and review over their work with a teacher or another experienced person. ...

Cognitive Processes

...Cognitive Processes (Author’s name) (Institutional Affiliation) Introduction Not all forms of learning can be captured by classical and operant condition. Learning takes place more efficiently through observation, imitation, taking and following instructing. Cognitive learning goes beyond imitation. It involves acquiring information through mental processes. In cognitive learning, one acquires information through listening, watching, touching and experiencing the stimuli before the message is committed to memory. This makes learning effective. Thesis statement. Most people are unaware of the importance of cognitive processes in their lives. Cognitive processes are important because they influence human behavior. When one is aware of his or her preferred approach, he or she is able to discern how his preference influences his personality. The aim of this paper is to look at three types of cognitive processes, their purposes and the methodology used in them. When a child is born the process of learning starts to take place. It has to learn how to crawl, stand, and walk and later on run. At puberty children learn various topics depending on the individual interests. However, before a man can apply what he has learnt he has to undergo a cognitive process. Carl Jung a Swiss psychiatrist came up with eight cognitive processes Introverted Intuiting, Introverted sensing, Extroverted Sensing, Extroverted Intuiting, Extroverted Thinking, Introverted Thinking, Extroverted......
