Industrial Uses of Ethene Ethene has two main industrial uses. Ethene is used to accelerate the ripening of fruits and is most commonly used on bananas and also on citrus fruits. The other use of ethene is in the manufacture of plastics‚ such as packing films‚ wire coatings‚ and squeeze bottles. Fruit: Ethene is made from the process of cracking hydrocarbons from petroleum. Ethene can then be used to make other raw materials like‚ ethanal‚ ethanol‚ and ethyl chloride. Ethene also occurs naturally

vary by several thousand gallons per ton. Water requirements. Currently‚ an approximate 75‚000 gallons of water are required to produce 1 ton of steel . However‚ this figure includes recycled and reused process and cooling water Water use in the iron and steel industry varied widely and depended on the availability of water‚ age and condition of plants and equipment‚ kinds of processes‚ and plant operating procedures. Gross water use in integrated steel plants ranged from 11‚200 to 110‚000 gallons

example‚ people generally clean coffee makers by brewing a nice fresh pot of vinegar. Vinegar contains acetic acid‚ which is a fairly weak organic acid. Nevertheless‚ sometimes acetic acid is enough. In other cases‚ you may want to purchase a commercial iron/coffee maker descaling product. Normally‚ this type of product comes in liquid or crystalline form. The key ingredient is usually sulfamic acid‚ an organic acid that is used for all kinds of interesting things. Sulfamic acid is an excellent descaling

understanding and knowledge about this element. I will cover specific information such as subatomic particles and availability in nature as well as information on the element’s isotopes. First of all‚ the element was not recognized to be different than iron until the 1600’s. Miners in Germany were trying to extract copper from ore‚ but were unsuccessful at any rate. They narrowed their problem down to a dark red ore‚ often with a green coating. This was the first accurate physical description given

Engineering Materials Used in Automotive Engine Blocks Abstract Until recently‚ cast iron and aluminum alloys have been the preferential materials used to manufacture most diesel and conventional gasoline-powered engine blocks. However‚ with a greater emphasis on increasing the efficiency of the engine via weight reduction‚ manufacturers have began to look for alternative alloys that are lighter than cast iron and aluminum alloys‚ while retaining the necessary strength to withstand the forces

general much more reactive than the ashes of fossil fuels. Lower reactivity of coal and peat ashes is connected to a composition with mainly quartz and various silicate-based minerals‚ like aluminium silicates‚ calcium silicates and alkali silicates‚ and iron oxides. Calcium and al kali in these minerals are not in free‚ reactive form like they are in biomass ashes. Accordingly they are quite inert at the conditions of fluidized bed combustion. Even though combustion of woody biomass fuels is more challenging
