How to Make Biodiesel From Vegetable Oil

How to Make Biodiesel From Vegetable Oil Biodiesel is a diesel fuel that is made by reacting vegetable oil (cooking oil) with other common chemicals. Biodiesel may be used in any diesel automotive engine in its pure form or blended with petroleum-based diesel. No modifications are required, and the result is a less-expensive, renewable, clean-burning fuel. Heres how to make biodiesel from fresh oil. You can also make biodiesel from waste cooking oil, but that is a little more involved, so lets start with the basics. Materials for Making Biodiesel 1 liter of new vegetable oil (e.g., canola oil, corn oil, soybean oil)3.5 grams (0.12 ounces) sodium hydroxide (also known as lye). Sodium hydroxide is used for some drain cleaners. The label should state that the product contains sodium hydroxide (not calcium hypochlorite, which is found in many other drain cleaners).200 milliliters (6.8 fluid ounces) of methanol (methyl alcohol). Heet fuel treatment is methanol. Be sure the label says the product contains methanol (Iso-Heet, for example, contains isopropyl alcohol and wont work).Blender with a low-speed option. The pitcher for the blender is to be used only for making biodiesel. You want to use one made from glass, not plastic because the methanol you will use can react with plastic.Digital scale [to accurately measure 3.5 grams (0.12 ounces)]Glass container marked for 200 milliliters (6.8 fluid ounces). If you dont have a beaker, measure the volume using a measuring cup, pour it into a glass jar, then mark the fill-line on the out side of the jar. Glass or plastic container that is marked for 1 liter (1.1 quarts)Widemouthed glass or plastic container that will hold at least 1.5 liters (2-quart pitcher works well)Safety glasses, gloves, and probably an apron You do not want to get sodium hydroxide or methanol on your skin, nor do you want to breathe the vapors from either chemical. Both chemicals are toxic. Please read the warning labels on the containers for these products. Methanol is readily absorbed through your skin, so do not get it on your hands. Sodium hydroxide is caustic and will give you a chemical burn. Prepare your biodiesel in a well-ventilated area. If you spill either chemical on your skin, rinse it off immediately with water. How to Make Biodiesel You want to prepare the biodiesel in a room that is at least 70 degrees F because the chemical reaction will not proceed to completion if the temperature is too low.If you havent already, label all your containers as Toxic- Only Use for Making Biodiesel. You dont want anyone drinking your supplies, and you dont want to use the glassware for food again.Pour 200 milliliters methanol (Heet) into the glass blender pitcher.Turn the blender on its lowest setting and slowly add 3.5 grams sodium hydroxide (lye). This reaction produces sodium methoxide, which must be used right away or else it loses its effectiveness. (Like sodium hydroxide, it can be stored away from air/moisture, but that might not be practical for a home setup.)Mix the methanol and sodium hydroxide until the sodium hydroxide has completely dissolved (about 2 minutes), then add 1 liter of vegetable oil to this mixture.Continue blending this mixture (on low speed) for 20 to 30 minutes.Pour the mixture into a widemouthed jar. You will see the liquid start to separate out into layers. The bottom layer will be glycerin. The top layer is the biodiesel. Allow at least a couple of hours for the mixture to fully separate. You want to keep the top layer as your biodiesel fuel. If you like, you can keep the glycerin for other projects. You can either carefully pour off the biodiesel or use a pump or baster to pull the biodiesel off of the glycerin. Using Biodiesel Normally, you can use pure biodiesel or a mixture of biodiesel and petroleum diesel as a fuel in any unmodified diesel engine. There are two situations in which you definitely should mix biodiesel with petroleum-based diesel: If you are going to be running the engine at a temperature lower than 55 degrees F (13 degrees C), you should mix biodiesel with petroleum diesel. A 50:50 mixture will work in cold weather. Pure biodiesel will thicken and cloud at 55 degrees F, which could clog your fuel line and stop your engine. Pure petroleum diesel, in contrast, has a cloud point of -10 degrees F (-24 degrees C). The colder your conditions, the higher percentage of petroleum diesel you will want to use. Above 55 degrees F, you can use pure biodiesel without any problem. Both types of diesel return to normal as soon as the temperature warms above their cloud point.You will want to use a mixture of 20% biodiesel with 80% petroleum diesel (called B20) if your engine has natural rubber seals or hoses. Pure biodiesel can degrade natural rubber, though B20 tends not to cause problems. If you have an older engine (which is where natural rubber parts are found), you could replace the rubber with polymer parts and run pur e biodiesel. Biodiesel Stability and Shelf Life You probably dont stop to think about it, but all fuels have a shelf life that depends on their chemical composition and storage conditions. The chemical stability of biodiesel depends on the oil from which it was derived. Biodiesel from oils that naturally contain the antioxidant tocopherol or vitamin E (e.g., rapeseed oil) remain usable longer than biodiesel from other types of vegetable oils. According to Jobwerx.com, stability is noticeably diminished after 10 days, and the fuel may be unusable after two months. Temperature also affects fuel stability in that excessive temperatures may denature the fuel.

Occupational Safety and Health as a profession Essay - 1

Occupational Safety and Health as a profession - Essay Example Occupational and environmental health and safety nurses, safety professionals, industrials hygienists, occupational health psychologists and occupational medicine physicians, are some of the occupational health and safety professionals. Other professionals that form a wider team of occupational safety and health multidisciplinary include toxicologists, human resource specialists, ergonomists, industrial or organizational psychologists and epidemiologists. These professionals have been accredited through certain specific procedures to practice occupational safety and health profession or offer services under occupational safety and health sector in accordance with the Regulation Act. Currently, there are no standards specific for occupational safety and health professionals. Work safety in almost all areas of the economy was worsened by the economic boom and the associated turnover in the labor that took place during the World War II (Fairris 187-203). However, as long-term forces reasserted themselves after 1945, accident declined again. In addition, nearly all powerful labor unions, after the World War II, played an increasingly fundamental role in safety at workplace. There were also increasing injury rates that were brought about by the economic expansion during the 1960s. It is important to note that OSHA took pre-eminence once the Massachusetts as a state began the inspections of factories, after the industrial revolution. Laws were put in place to safeguard the state workers and ensure their safety in 1913, thus, they were ratified in the constitution. This implies that the employers were responsible for the injuries accrued by their employees during working hours. In subsequent years, in 1969, the Department of Mines and Minerals was effected to cover the employees a year before the whole industry was covered by the OSHA act. Due to this increase and the increasing political pressures, the Congress, in 1970, was forced

Dentify the basic provisions of the Sarbanes-Oxley Act that Essay

Dentify the basic provisions of the Sarbanes-Oxley Act that specifically deal with ethics and Independence and research how this Act has affected auditors since it was established in 2002 - Essay Example An example is the collapse of Enron. Unethical conduct on the part of Corporate CEOs and Audit Firms was responsible (Rezzy, 2007). To avoid a repeat of the same, the Sarbanes-Oxley Act was passed to instill ethics and instigate independence auditors. The essay covers specific provisions of the statute intended to promote ethics and independence to demonstrate how the act has affected auditors. Section 101 created the Public Company Accounting Oversight Board as an independent body with the onus to monitor and regulate the activities of auditors (Freeman, 2009). The board has since ensured that auditors comply with the provisions of the legislation as well as comply with the code of ethics for persons in the auditing business. Since the introduction of the Board, it is believed that audit malpractice has reduced due to the stiffer penalties that threaten implicated firms as a result of the Board’s investigations according to Romano (Romano, 2005). Title III from section 301 to 308 endeavors to promote ethics by obligating company executives to be personally responsible for the financial reports of the corporate, whether quarterly, semi-annually or annually. To avoid malpractice, CEOs and other chief management staff are required to inspect and pass as accurate the financial statements of the company before they are released. This in turn makes the officers personally liable if any misstatements are made that could be misleading as to the financial soundness of the company. Green states that any officer required to append signature on a financial report must only do so after doing due diligence using their knowledge to make sure that everything stated therein is true to avoid personal liability (Green, 2004). This has had the effect of reducing fraud as corporate executives struggle to ensure that financial reports are as accurate as

Not waving but drowning Essay Example | Topics and Well Written Essays - 1000 words

Not waving but drowning - Essay Example In each of these states, whether European or American, people were experiencing a great deal of alienation and isolation as a result of these tremendous changes. Perhaps it is not surprising, then, to find the desolation and isolation of this period reflected as a major theme in the poetry created during this period such as â€Å"Not Waving but Drowning† by Stevie Smith. The isolation is almost overwhelming in Smith’s poem as she begins with the desolate lonely cry of a man that nobody hears. Although he is introduced as being dead, â€Å"Nobody heard him, the dead man, / But still he lay moaning† (1-2), making himself known to someone. This introduction presents several possibilities as to his true condition. The first is that the man is only symbolically dead, dead on the inside, and so is physically alive and able to moan in his continued pain and loneliness. He could also be so close to death that there is no possibility of saving him before he’s gone, and he’s moaning in anticipation of the inevitable. Another possibility is that he is actually dead, but there remain a few possibilities as to his continued moaning. The pain and anguish of his death might have been too much for him to bear and thus he is still moaning even after death. Finally, the suggestion that nobody heard him invokes the sense of the ghostly, so that perhaps the man is moaning in the form of a ghost, attempting to warn those who can hear of the dangers of allowing individuals to become too isolated from society. The words that Smith provides him in the second portion of this stanza further emphasize the sense of isolation and failed attempts at connection. The dead man says, â€Å"I was much further out than you thought / And not waving but drowning† (3-4). This indicates that whether he was alive or dead, this man never felt as close to his fellow humans as they perceived him to be and, as a result, they were unable to recognize the signs of distress he was sending

Business as a form of premeditation and the expectations Essay

Business as a form of premeditation and the expectations - Essay Example This research will begin with the statement that going through the state of a business is one of the contemporary and most recognized ways through which modern-day business people recognize the strengths and weaknesses of a certain business. The business under review, in this case, is a small business, a wine shop. It is important to go through the general situation that the business thrives in an effort to understand the best way to manage it. The size of the business is generally small and deals with the sale of wines. The large part of the business can be sighted after the first entrance to the shop as it does not have multiple doors except one leading to the storage room. There are racks present in the premises where the wines are stored until customers come to purchase it. The business is in an open place and thus there is sufficient lighting. Moreover, there are also bulbs in the premises since the sale of wine goes on to the night. There are two assistants who assist in the or dering and the arrangement of material in the premises. In addition, there is a telephone for the customers who might want to book a certain brand of wine. The business in question is rather thriving in an environment that has a lot of active customers. This is got from the manner in which it has managed to have a steady flow of sales per unit. This one of the aspects that keeps a business alive and conformation with the environment generally comes in as another positive chip. The breakeven point is recognized as the point in business where the revenue that the company makes is equivalent to the amount of expenses it incurs. In the stated business, the breakeven point is high. This is from the fact that the company had to sell whole 71000 units in an effort to have the small margin that exists. The margin between the revenue and the expenses is minimal at 30 for every unit and this sets in as a risk for making deficits to the company rather than the large profits that every business speculates. The business itself is in a proper category to buy even more alcohol; however, the amount of money that it makes is not sufficient enough to make a large investment such as the acquiring of another staff member. Having seen the shallow margin that the business makes has implications for the business. These implications come in as both positive and negative regarding the time it takes. If the business has short term goals, the small margins cannot come in handy in their fulfillment. However, in the accomplishment of long term goals for the business, this can work as cumulative amounts of money would get retained in the business after deduction of the general fixed costs that are the rent, staff costs, telephone and others. Going through the profitability of the business is another major aspect to bring in when identifying the actual stature of the business (Barrow, 2011,57) Looking at the sales that the business makes, it is clear to state that the profitability of the business is in line with what a small business of the sort. This is from the fact that a business entity such as the wine shop managing to have 20 Euro profit margins per unit is great. When that amount of money is multiplied with the amount of units sold in a year, the total exceeds initial capital investment by far. Understanding the liquidity of the company is another aspect that a company ought to consider when going about the daily running (Blackwell, 2008, 75). This is from the fact that for a business to keep on running, it is important to ensure that in case of anything the amount of money lost is not much. The business is well set in this from the previous fact stated regarding the amount of money that the business makes in a whole year. The wine industry is one industry that is always up from the fact that it does not have seasons and is not affected by factors such as weather. If the

Implementation of a COP program based on the scenario given Assignment

Implementation of a COP program based on the scenario given - Assignment Example There is also a citizen’s patrol project which will help the police with monitoring areas where there may not be a patrol at that moment so help can be called in immediately. An outline and overview of the project is given in this paper as to how it will be implemented. Introduction This is a proposal memo to address the problems at the Anytown Shopping Mall in our city which has had a 75% increase in crime and robberies over the years 2009 to 2011. In light of the fact that it is determined that homeless people have set up camps in parking lot areas where there is very little lighting installed, and that there have been numerous robberies conducted in parking lot sections, the Anytown Police Department is designing a project to help with cutting down crime and restoring a safe environment for our citizens to be able to shop and work safely in, and around, the Anytown Shopping Mall. It is our plan to bring back businesses to this area as a number of the shopping mall businesse s have left recently because of the unsafe conditions for both workers and customers (Class information 2013). The community-oriented policing program being created is called ANYTOWN ANYTIME FREEDOM SHOPPING program which will address several issues: eliminating transit camps in parking lots, a system of patrols that covers all sections of the parking area and in the mall as well, a protection system for workers and customers of the mall and finally, a determination of what public works projects must be developed, such as a new lighting strategy, for all areas of the parking infrastructure (Class information 2013). 1. The social forces that exist for this problem are that there are numerous homeless people who are camping out in the poorly lit areas of the shopping mall’s parking sections, particularly in underground parking. This creates an unsafe hazard for those workers who must come in early and leave late at night (Craven 2009). For shoppers, the danger is the high chanc e of being robbed, particularly when carrying packages. Aside from the obvious dangers from robberies, muggings, and potential car jackings, the areas where there are camps are very unsanitary, particularly as there are no restrooms (Dempsey & Forst 2013). It is unclear at this time whether the homeless also go into the shopping mall, when it is open, in order to use the restroom facilities. Preparation 2. The first steps in preparing for the program is to have a meeting, or several meetings, with shop owners in the mall in order to hear what incidents they have encountered, which would help in designing the plan of action (Craven 2009). This would also include those businesses which have left the area and finding out specifically what issues they had as regards conducting business in the mall. In addition to the meetings, it is also important to assess from crime reports where crimes in that area have occurred the most and what type they are (Hunter & Barker 2011). Once this inform ation has been developed, then more strategic planning can take place. 3. The social and special interest groups that should be involved in this process are the business owners in the mall, the shopping mall administration officers, any current security teams that are already in place, as most malls have their own team, and also the city manager and district representative. It is important to have reflections from all the above people and to have them
