In the coal gasification process the air and stream are added to the raw coals then heat it to hundred degrees Fahrenheit. The carbon in the coal then react with the oxygen and the water then produces other gases such as carbon dioxide, carbon monoxide, hydrogen and methane. The carbon dioxide from the process is waste and can go to the atmosphere. The other gases can be burned or sent to the next process. Then the second process is after we get the processed and filtered coal, gas or water or carbon dioxide can be added to balance the amount of carbon monoxide and hydrogen.
The casting process: Lynchburg and Archer Creek Plants A casting was made by pouring molten metal into a sand mold of the desired shaped. Once the metal, leaving a casting. There were four steps in making a casting: melting and allowing the metal, making molds and cores. Melting and Alloying The raw matterials were received by rail car in the iron yard behind the plant. The raw materials included coke for melting fuel, limestone to promote the coagulation of slag or impurities, pig iron for carbon and silicon, and steel scrap for the iron
Absorptivity of Bentonite Clay Final Project CHEM 112-501 Melissa Cisneros* Danielle Salo The purpose of this experiment was to test the absorptivity of Bentonite clay, charcoal, and another type of clay. Bentonite clay as well as charcoal can be used as a means of removing pollutants such as Polycyclic Aromatic Hydrocarbons (PAHs) from water sources. Materials and Methods: Materials used in this experiment were 600 mL beaker, 250 mL Erlenmeyer flask, 50 mL graduated cylinder, ring stand and clamp, thermometer, hot plate, tongs, pipet, spatula, centrifuge tubes, a centrifuge, cuvettes, and a spectrophotometer. Chemicals used were FeCl3 Anhydrous, FeSO4- 7H2O, Bentonite clay, 2.5 M NaOH solution, and Procion Red MX-5. To make the clay, 250 mL of distilled water was heated in a 600 mL beaker to 70° to be used as a hot water bath for the Erlenmeyer flask.
Tungsten is also used as a target for X-ray production, as heating elements in electric furnaces and for parts of spacecraft and missiles which must withstand high temperatures. Tungsten is alloyed with steel to form tough metals that are stable at high temperatures. Tungsten-steel alloys are used to make such things as high speed cutting tools and rocket engine nozzles. Tungsten carbide (WC) is an extremely hard tungsten compound. It is used in the tips of drill bits, high speed cutting tools and in mining machinery.
Lab 8: “Determining the Cooling Time Constant for a Block of Steel” Introduction: In this lab experiment we will be determining the cooling time constant of a block of steel. This will be done using Newton’s Law of Cooling. Procedure: To begin the lab we will need a hot plate, a block of steel, a digital thermometer, and oven mitt, a fan, and a block of wood. The first step of the lab is to place the block of steel onto the hotplate and heat it to 150 ° C. After the block of steel is heated to 150 ° C remove it (using the oven mitt) and place it on the block of wood. This is just to avoid the hot steel damaging the table.
Secondly, the need for steady water supplies had a great deal of impact on the economies of ancient civilizations. In many places, such Rome and China, thousands upon thousands of workers were needed to build the giant aqueducts and irrigation canals. Likewise, large numbers of workers were also required to maintain these structures once they were completed. These massive projects put people to work, as well as lowered the rate of unemployment, and history shows that economies
As people come into riches and their wealth increases, they are only further enslaved. When Wang Lung comes into riches, many unwanted guests wind up staying at his house. For example, Wang Lung’s uncle, his uncle’s wife, and his cousin invited themselves into his home. Having the extended family stay with them made life much harder as they would get less food, and the guests occupied everyone’s time with all of their requests and demands. This made Wang Lung more enslaved because he had to tend to their every need.
Electric arc furnace steel slag is an industrial by-product obtained from the steel manufacturing industry during melting of steel scrap from the impurities and fluxing agents. Electric arc furnace steel slag is obtained by cooling the electric arc furnace steel liquid slag in air at production site, [18]. The composition of slag varies upon the type of furnace and charge, the desired grade of steel purity and the furnace operation conditions, [6]. Steel making process in electric arc furnaces generates up to 15 % of slag per ton of steel, which is, based on its properties, classified as nonhazardous waste. Major components of steel mill slag include Ca-silicates,
It was a very important part of life and everyone needed it. That why Jerusalem had to have water near it. Evan today the water is a necessary thing to live
My life would be a lot more difficult because I would be in a state of constant confusion and it would be very scary to live life without remembering. A life with Alzheimer’s is definitely not easy, especially when you are showing early signs of it and you understand what is happening to you, it can be extremely hard to deal with. I would be devastated and my life would be increasingly harder to live. I would not be able to tell my grandkids stories from my past or help my own children when they need it, I would not be able to cook dinner for my husband or even hold a conversation with him without forgetting who he is or where I am. My life would be completely different from how it is now.
