Normally, emulsified water is generally present in crude oil as a result of the mixing occurring during production operations and referred to as oil field emulsion. This emulsion can be encountered at numerous stages include during drilling, producing, transporting and processing of crude oil. However, the formation of emulsion creates problems in oil field industry. They might increase the cost of production and also transportation; accumulate in the refinery tank age, pipeline corrosion, equipment failure, plugged pipeline. For economic and operational reasons, it is necessary to remove water completely from the crude oil emulsion before refining and transporting those. In order to separate the water content of the produced crude oils, the emulsions have to be broken through demulsification process.
Demulsification is defined as a process of breaking emulsions with intention to separate water from oil. This emulsion breaking is necessary in many practical applications as the petroleum industry and waste water treatment in environmental technology. The emulsion stability results from the presence of interfacial barrier preventing coalescence of the

Commercial demulsifiers are formulated in solvents such as short-chain alcohols, aromatics, or heavy aromatic naphtha and can contain a mixture of several active matters. There have three main methods to demulsify the emulsion namely mechanical, electrical and chemical. However, chemical method is most widely used. Basically, chemical demulsification consist of the addition of small amount of breaking agent (usually 1-1000ppm) to enhance the phase separation. Thus, there have four groups of breaking agents which were consisted with amine, natural, polyhydric and alcohol demulsifiers
The boiling point of the product was conducted with the silicone oil. Lastly, for each chemical test, three test tubes were prepared with 2-methylcyclohexanol, the product, and 1-decene in each test tube, and a drop of the reagent were added to test tubes. The percent yield was calculated to be 74.8% with 12.6g of the product obtained. This result showed that most of 2-methylcyclohexanol was successfully dehydrated and produced the product. The loss of the product could be due to the incomplete reaction or distillation and through washing and extraction of the product. The boiling point range resulted as 112oC to 118oC. This boiling point range revealed that it is acceptable because the literature boiling point range included possible products, which are 1-methylcyclohexene, 3-methylcyclohexene, and methylenecyclohexane, are 110 to 111oC, 104oC, and 102 to 103 oC. For the results of IR spectroscopy, 2-methylcyclocahnol showed peaks at 3300 cm-1 and 2930 cm-1, which indicated the presence of alcohol and alkane functional group. Then, the peak from the product showed the same peak at 2930 cm-1 but the absence of the other peak, which indicated the absence of the alcohol
In order to separate the mixture of fluorene, o-toluic acid, and 1, 4-dibromobenzene, the previously learned techniques of extraction and crystallization are needed to perform the experiment. First, 10.0 mL of diethyl ether would be added to the mixture in a centrifuge tube (1) and shaken until the mixture completely dissolved (2). Diethyl ether is the best solvent for dissolving the mixture, because though it is a polar molecule, its ethyl groups make it a nonpolar solvent. The compounds, fluorene and 1, 4-dibromobenzene, are also nonpolar; therefore, it would be easier for it to be dissolved in this organic solvent.
The solvent should be easily removed from the purified product, not react with the target substances, and should only dissolve the target substance near it’s boiling point, but none at freezing. A successful recrystallization uses minimum amount of solvent, and cools the solution slowly, if done to fast, many impurities will be left in the crystals. Using the correct solvent, in this case ice water and ethyl acetate, the impurities in the compound can be dissolved to obtain just the pure compound. A mixed solvent was used to control the solubility of the product. The product is soluble in ethanol an insoluble in water. Adding water reduced solubility and saturates the solution and then the crystals
Grease the hit music sensation of the late 70’s and early 80’s took the Hollywood industry by storm. Not only is Grease a classic, but it was the start of theme of high school musicals. There is an enormous amount differences between Grease One and Grease two, it’s almost heart breaking. The music and theme are completely different it’s difficult to tell that it’s a Grease sequel.
After the oil/gas mixture is drawn from the ground, it is then stored into a storage tank and allowed to rest for a while. Then the gas is piped off to a set of distillation columns to clean up the ethane. In order to activate the chemical reaction necessary to separate the ethane, a thermal cracking unit (a sort of long heated tube) i.e. a plug flow reactor is used. After a series of distillations, ethylene exits the tube.
An emulsion is a mixture of two immiscible liquids. Immiscible liquids, such as water and oil, are unable to mix without a third party, which in this experiment is the xanthan gum and whey powder, because of the polarity of the liquids. Because water is polar and oil is not, it is impossible for both of them to be mixed.
The first step is choosing a suitable recrystallization solvent. This step is crucial when it comes to executing a successful recrystallization experiment. Solubility comes into play when choosing a proper solvent. When choosing a solvent, its polarity must be similar to the compound that will be purified, in this case, the compound acetanilide. The principle of “like dissolves like” can be used to understand this simple concept.
You are living in Saskatoon where the current temperature is -41o C. What happens when you need to suddenly go to the hospital, and your car engine oil is as thick as a jelly which makes it hard for the car to start properly? What’s going to be your first priority changing your petroleum-based engine oil into the Synthetic oil or deciding not to go to the hospital even though you needed it at any cost?
Durian is the most well known occasional natural product in Indonesia. Just 1/3 of durian is consumable, though the seeds are discarded. This waste is capability of significant worth included, for example, seed gum. Mayonnaise is o/w emulsion based item utilize egg yolk as an emulsifier, yet in this exploration, durian seed gum (2.5%, 3%, 3.5%, 4%, and 4.5%) has been utilized to supplant on egg yolk in making veggie lover mayonnaise. The best plan of veggie lover mayonnaise from 4% durian seed gum was contrasted with business and the control also. This outcome is comparable to mayonnaise with egg yolk, and the business mayonnaise. Past examinations uncovered that the characteristic polymer of gum durian seed had emulsifying action oil in water (o/w). Common gum was a polysaccharide comprising of monosaccharides connected through glycoside bonds. Common gum polymers are normally unpredictable, produced a considerable measure of plants, for example, carrageenan, pectin, CMC, starch, guar gum, and sodium carboxyl. Methyl cellulose was utilized as a gelling operator, thickener, stabilizer, emulsifier. Fluid extraction was a standout amongst the most well-known methods utilized for the extraction of gum. Gum durian seeds can be utilized
ne, which are used to manufacture chemicals. Or the residual from the distillation tower is heated 482°C, cooled with gas oil and rapidly burned in a distillation tower. This process reduces the viscosity of heavy weight oils and produces tar. The other method of cracking is called Catalytic Cracking and it uses a catalyst to speed up the cracking reaction. Catalysts include zeolite, aluminium hydrosilicate, and bauxite.
The rainforests around the world have been dwindling to the point where we will soon have no more in the world. We lose an ecosystem for Creatures as we deforest the area and plant crops for products we do not need such as palm oil. Animals, Such as the orangutan, face the destruction of their homeland with us continuing to increase the production of palm oil. What could make this change? Decreasing the use of palm oil, an ingredient contained in multiple products we use daily, can help decrease the deforestation in the rainforest and allow animals such as the orangutan to thrive. Palm oil became relevant to us only years ago.
...ticles pack closer together within the paste. Due to the viscosity and hence reduced flow of the binder through the interparticle spaces, the consolidation process is slowed down, effectively delaying any excessive ball growth. This research aims to investigate the granulation mechanisms involved in a high viscous detergent system in order to gain an understanding into how a high viscous binder is dispersed compared to a low viscous binder. This research would not be working with any low viscous binders and would be comparing research results with published work done on low viscous binder granulation systems. Most importantly, the research would focus on effects of process parameters such as binder injection point (literature on which has not been found) and granulation time as well as impeller speed and binder amounts (with considerably more literature published).
Laundry detergents have had a great impact on the society since it helps our life in keeping ourselves clean, lessens our job or the use of our energy in cleaning our appliances. Laundry detergents have come a long way since the very first bar soaps, made from animal fat and lye, were offered for sale in the 1700s. In the 1950s, homemakers had more options of fabric care since the introduction of synthetic detergents were placed on the market. However; during the 1970s, the most significant innovation in advanced cleaning was made available to clean specific types of stains. Every detergent manufacturer has secret ingredients and mixtures to produce their specific brands of laundry detergent. Many of these ingredients are extracted from plants,
The oil refinery converts crude oil into valuable products and supplies. These products are made and sent to many countries abroad, in which are transported on land or along rivers and canals. Crude oil is then arranged and categorized into segments by fractional distillation. Raw crude oil, or unprocessed crude oil, is not normally beneficial in most industrial applications. Low sulfur crude oil has been valuable as a burner fuel to construct steam for the force of seagoing vessels. The lighter elements have the ability to construct explosive and dangerous vapors in the gas tanks. There are extremely hazardous, and are often used in war ships. The remaining hydrocarbon molecules are filtered from crude oil and used towards lubricants, feedstock, plastics, and fuels.
There are both consumable and mechanical structures created from the seed of any of a few cultivars of the plant family Brassicaceae. Japan is one of the world's biggest economies and one of Canada's most critical financial and business partners.
