Paraffin

which used to mix with ground nutmeg seed and wash the residue, is not very toxic but highly flammable and also has easily evaporable property. From this reason, we have to pay special attention to flame around us when doing experiment. Paraffin, which composes paraffin oil, is also flammable so that it can catch fire easily. When adding ground nutmeg seed, acetone and heating it with heating mantle, it is important to gently swirl the solution to avoid bumping. It can be more secure to add anti-bumping

Flow assurance is a term created by Petrobras in the early 1990s aiming to ensure successful and economical flow of hydrocarbon stream from reservoir to point of stream. Wells located in water deeper than 1200 feet require flow assurance. Deep water temperatures can get down into the thirties depending on the depth of the well. Because of the low temperatures the fluid within the wells may have issues flowing. Some issues could be hydrate, scale, corrosion, and asphaltenes. The best way to combat

When thinking about how all this oil and gas gets from the platforms in the gulf to land to be produced, you will run across the phrase, “flow assurance.” Flow assurance is what makes sure these oils and gases get from point A to point B without any hesitations or problems. Its main purpose is to prevent hydrates, clogged pipes, and wax depositions. So can the oilfield industry survive without flow assurance, especially in deep water operations? By reading this, you will learn how important flow

were the light was on, however only to find that there was no light. Not only were there no physical lights as seen in today’s modern houses. However there was a small paraffin lamp on the shelf, which had no trace amounts of paraffin and was ice cold, meaning it, had not been used in a long time. As I was busy investigating the paraffin lamp, I did not notice both Jake and Spencer left the room. I turned around to face the rest of the room and to my horror, I was left alone. I casually walked out into

We all know about energy sources, but I am about to tell stuff that you probably didn’t know before about oil. The oil we pump to the surface is a mixture of gasoline, kerosene, light weigh5 lubricating oil, motor oil, tars, paraffins, waxes, asphalt, sand, dirt, aromatics, and dead cockroaches. Plus oils have a high carbon and hydrogen content and are usually flammable and slippery. Approximately 50% of oil is used for transportation industry, And the united states has over 200,000 miles of

Experimenting with a Candle Justin Nguyen Mrs. Howley 11/16/11 Mod F Purpose: the purpose is to learn how the process of a candle burning. The goals of this experiment are to practice in the art of observation, the art of questioning, and the development of a better understanding of this process. Hypothesis: through this experiment, we will learn how candle is working. Materials: * Candle * Note card * Matches or butane lighter * Aluminum foil * 1L beaker * Balance

cross-links effectively. However, this molecule is larger than that of formaldehyde, so it is not possible to use in paraffin embedding, because the large wax molecules would be unable to penetrate the tissue after fixation. The largest disadvantage of this exceptional fixative is the higher cost, both of the materials required for fixation, and for the required plastic embedding rather than paraffin. On the other hand, the benefits of using Karnovsky’s fixative often outweigh the increased cost. The cytological

A crayon is a stick of colored wax, charcoal, chalk or other material used for writing or drawing. A crayon made of pigment with a dry binder is a pastel; when made of oiled chalk it is called an oil pastel. A grease pencil or china marker is made of colored hardened grease. There are also watercolor crayons, sometimes called water-soluble crayons. Crayons, which are available at a range of price points, are easy to work with, often less messy than paints and markers, blunt, typically non-toxic

cylinders with 500-ml capacity will be needed on each table. 2. Each of the cylinders needs to be covered on the inside with paraffin wax that can be applied with forceps and cotton. 3. Transfer the flies of a vial into the cylinder using a funnel. Ensure that during the transfer process, the funnel is kept in a vertical position so that the flies do not come in contact with paraffin layered cylinder walls. 4. The ability of the flies to fly measure their flying potential. The flies with good flying
