Abstract

Waste tire related environmental problems and its recycling techniques have been a major challenge to society. The abundant and indiscriminant disposal of waste tires has caused both health and environmental problems. Current waste tire recycling market is too small to accommodate the tire generated annually. Therefore, it is of crucial importance to develop new markets for waste tires. Oil is one of the most important energies and raw material sources for synthetic polymers and chemicals worldwide. Whenever oil is explored, transported and stored, there is risk of spillage with the potential to cause significant environmental impact. Pollution by petroleum oils affects sea life, economy, tourism and leisure activities because of the coating properties of these materials. Tire rubber is flexible and has hydrophobic (oil-philic) characteristics, making it a good candidate as oil absorbent. In this study, the possibility of applying waste tire powder as a sorbent for the recovery of spilled oil was explored. Rubber particles of mesh sizes within the range of 0.5 to 1.65 mm were used to absorb different oils at different temperatures. The results of this study indicated that sorption capacity increased as the tire powder particle size decreased and environmental temperature increased. Similarly, sorption capacity increased for the

    Siam Cement’s offer to purchase an initial order of 200 units at $9,000 per unit, would lead to a net profit of $200,000. While this immediate cash influx may seem advantageous in the short term, it will not offset yearly operational expenses of $250,000 (See Exhibit 1). Additionally, accepting Siam Cement’s offer would position Rubbertech as an Original Equipment Manufacturer (OEM). This decision could impede potential growth that would far exceed the offer that is currently on the table. If Rubbertech does not accept Siam Cement’s offer, they can seize a part of $5.4 million total market share (Eisenstein 2006). In this case, the potential for reward clearly justifies the risk involved.…

    Natural rubber [poly-cis-isoprene(C5H8)n]. the latex consists of a polymer colloid of a monomer called isoprene. The precipitation of the rubber particles from the latex produces an elastic, sticky, gummy mass. In 1839, Charles Goodyear found that by vulcanising (ie. Cross-linking the polymer chains) the natural rubber a non sticky elastic was produced. This vulcanised natural rubber soon became used in a wide variety of products including tyres, insulation, matresses and rainwear. Rubber production could not keep up with demand, especially from the vehicle industry. A synthetic replacement was needed. And today synthetic polymer production accounts for 80% of the worlds rubber production.…

    Chemistry, while usually thought of as being practiced mostly in labs, actually affects everyone, everywhere. Chemistry and chemical processes are constantly occurring. We are dependent on them. The air that we breathe, the food that we eat, and thousands of other simple and confusing things depend on chemistry. In this particular case, the relationship between Polyvinyl Alcohol (PVA) and Sodium Borate (Borax) is being investigated. PVA is a water soluble synthetic polymer (Maciborski, and Salamone), while Borax is a natural mineral with many household uses. It can be used as herbicide, to bleach teeth, as a household cleaner, and a laundry booster, to name a few (Helmenstine).…

    3.3 Results and Discussion 3.3.1 Particle Size of Asphaltenes. DLS was utilized to obtain the hydrodynamic radius of asphaltenes in toluene, which could help understand the behaviors of asphaltenes in the bulk solutions and oil/water interfaces. Figure 1 shows the particle size distribution of asphaltenes under different concentrations at 23 ℃ and under 2000 mg/L at different temperatures. A summary of the average particle size under different concentration and temperature conditions is shown in Table S1 and Table S2 in the Supporting Information. Figure 3.1 Size distribution of asphaltene aggregates measured by DLS for asphaltene solutions in toluene of different concentrations (i.e. 50 - 2000 mg/L) at 23 ℃ and 2000 mg/L asphaltenes in toluene solution at 50 ℃ and 70 ℃.…

    People believe that when celebrities use social media it forces upon us a false sense of intimacy and closeness that does not actually exist. Social media makes us think that the stars we love really are just like us because it appears as though these celebrities are making themselves seem like less of a “star” and more like a normal human being. Sure, we see their life on an intimate level through personal pictures and tweets that they choose to post, but in comparison to our friends, we know next to nothing about these celebrities. With that being said, although social media, such as Twitter, has allowed us to have more access to celebrity’s personal lives, we are only exposed to the information…

    Effects of Oil Spills

    • 339 Words
    • 2 Pages

    There are 3 main ways to separate oil from water and 3 absorbents that can be used. The first way to remove oil is A belt, hose or disc, moves through a layer of oil, which causes the oil to adhere to the surface and be carried off. The second way is to Coalesce which is when smaller oil drops in an oil/water mixture will separate slowly or not at all. Coalescing media is placed in an oil separator to catch and accumulate the finer oil drops then merge them into larger drops that separate quickly. The third way is where the three absorbents come in which is Gravity separation, which is a fancy way of saying the oil and water layers are prominent. Two of three of the absorbents are fairly fast at removing oil. The third, well helps decompose the oil faster. The first absorbent is human hair, most people can see why because it grasp onto oil and keeps it but that way is kind of messy. The second absorbent is Saw dust which is a little cleaner then the hair but just about as messy. The third way which dose not really absorb as much as decompose the oil is using pure nitrogen and phosphorus to form little Tar balls which aren’t as deadly to the environment as the liquid crude oil. But no there is a forth absorbent let to be endorsed by the government. It is a polymer called WENV-250 and it was developed by a scientist to remove oil more defiantly. The polymer is non toxic so it may be used to put on birds feathers then simply pulled…

    Let me tell you a little bit about this chemistry of oil. Oil is a stew of hydrocarbon molecules. It starts of with the very small ones, which are one carbon, four hydrogen -- that's methane -- it just floats off. Then there's all sorts of intermediate ones with middle amounts of carbon. You've probably heard of benzene rings; they're very carcinogenic. And it goes all the way over to these big, thick, galumphy ones that have hundreds of carbons, and they have thousands of hydrogens, and they have vanadium and heavy metals and sulfur and all kinds of craziness hanging off the sides of them. Those are called the asphaltenes; they're an ingredient in asphalt. They're very important in oil spills.…

    Minimum wage policy will lead to surging unemployment, “black market” labour and inflationary pressure, employers and economists have warned. Datuk Seri Najib Razak announced on Monday a base wage of RM900 for the peninsula and RM800 in Sabah and Sarawak with a grace period of six months, or doubles that for micro-enterprises. “When employers refuse to hire at the minimum wage, desperate workers will look to the black market and agree to take less than that,” said Wan Saiful Wan Jan, chief executive of libertarian think-tank Institute for Democracy and Economic Affairs. The government began working on a minimum wage policy last year after over a decade of pressure from labour unions during which productivity rose by 6.7 per cent annually but real wages inched up by just 2.6 per cent each year. Malaysian Employers Federation executive director Shamsuddin Bardan also said that in some cases, such as plantation workers in Sabah, a minimum wage of RM800 would double salaries. “On top of that, if Najib wins elections as expected, subsidy cuts will resume. In the end there will be very little positive impact for workers,” said Hafiz Noor Shams, an economist at a leading investment bank. Shamsuddin suggested instead that instead of “using the force of law,” the government should incentivize both employers and employees to upgrade the skill base of the workforce. The Human Resources Ministry says three-quarters of the 12 million-strong workers are unskilled. When there are un skilled workers, there are hard to give them a high salaries. This is because. It take time to make them…

    Strategies for dealing with industrial liquid wastes involve both reducing the quantity produced and their environmental impact. So there is a considerable amount of research work going on throughout the world for better and better technologies for reduction, recovery and recycling of hazardous liquid wastes. Adsorption methods using activated charcoal and biological treatment are the presently practicing methods industrially for the treatment of liquid discharges. However these are not very energy efficient methods. Pervaporation proves to be a good alternative to the currently practicing methods of recovering organic solvents from process effluents since it has the advantages – improved selectivity, reduced energy consumption and separation of azeotropic mixtures and mixture of components with close boiling points.…
