Study and Characterization of Waste Vegetable Oil Blending with Mineral Turpentine and Performance Test on I.C STUDY AND CHARACTERIZATION OF WASTE VEGETABLE OIL BLENDING WITH MINERAL TURPENTINE AND PERFORMANCE TEST ON I.C. ENGINE COLLEGE : SHAIKH COLLEGE OF ENGINEERING AND TECHNOLOGY, BELGAUM DEPARTMENT : MECHANICAL ENGINEERING GUIDE : PROF. VEERANNA.D.K STUDENTS : MAHESH NAVAGEKAR RAGHAVENDRA MAYEKAR ADITYA KAPSHIKAR PRAMOD KORE Key words: biodiesel, waste cocking oil, blending Introduction/Background: The use of vegetable oils in diesel engines is nearly as old as the diesel engine itself. The inventor of the diesel engine, Rudolf Diesel, reportedly used groundnut (peanut) oil as a fuel for demonstration purposes in 1900 (1). Some other work was carried out on the use of vegetable oils in diesel engines in the 1930's and 1940's. The fuel and energy crises of the late 1970's and early 1980's as well as accompanying concerns about the depletion of the world's non-renewable resources provided the incentives to seek alternatives to conventional, petroleum-based fuels. In this context, vegetable oils as fuel for diesel engines were remembered. They now occupy a prominent position in the development of alternative fuels. Hundreds of scientific articles and various other reports from around the world dealing with vegetable oil-based alternative diesel fuels ("biodiesel") have appeared in print. They have advanced from being purely experimental fuels to initial stages of commercialization. Nevertheless, various technical and economic aspects require further improvement of these fuels. Objectives: 1. To collect the waste vegetable oil from large hotels. 2. To study and characterize the biodiesel produced by waste vegetable oil without trans esterification. 3. Finding of properties like calorific value (CV), viscosity, flash point, fire point, density and various properties of the oil by using laboratory equipment 4. To study the suitability of the oil for running the IC engine. 5. To conduct the performance test and evaluation of the results with respect to the standard fuels. 6. To reduce the cost by using SVO into IC engine. Methodology: 1. To collect released used cooking oils or waste vegetable oil from large hotels. 2. To Heat the oil to reduce viscosity, and Filter it. 3. Centrifuge the oil (settle down the fine particles down) 4. To investigate the various properties of the waste vegetable oil. 5. To blend the mineral turpentine with released waste cooking oil from large hotels in various proportions and study the properties of these blends. 6. To arrive at a proper combination of this blend to ensure miscibility and FFA below required limits. 7. To keep the samples for one week. 8. To characterize the methyl Easter so produced by determining Viscosity, Flash & fire Point, Calorific value and Copper Corrosion test. 9. To use these blends in a CI engine and check the performance and emissions. Results and Conclusion: Experiments were conducted on direct injection compression ignition engine using diesel, waste cooking oil and its blends with turpentine with blend composition varied from 5 to 10% in steps of 2.5%. Base line readings were also generated with existing uncoated diesel engine for the comparative study. The engine speed was kept constant at 1500 rpm and the compression ratio of 17.5, injection timing of 23oC and injection pressure of 230 bar were maintained throughout the experiment. Future scope: The project can be taken up in large scale and the results are very near to the diesel fuel so can be used as an alternate fuel for the automotives. .

  • Varnishing Than with Any Other Stage of the Painting Process
    INFO SHEET 301 UPDATED JULY 2016 VA R NISHING We get more questions about varnishing than with any other stage of the painting process. Varnishing should be an almost mechanical process undertaken to give your painting a protective coating with the surface quality you prefer (gloss, satin, etc.) and possibly an enhancement of colour contrast. But, if you leave it till the last moment and use a varnish you are not used to, you can ruin the work you are trying to protect. Anxiety and disappointment can be avoided easily if you do sample pieces using the same materials as the painting and varnish them, not the painting, until you get the effect you wanted. Water-based varnishes are tricky to apply and not removable if you dislike the effect, so we suggest they should only be used by artists who have already tried the above experiment. CHROMA SOLVENT FINISHING VARNISHES We recommend and prefer our Chroma Solvent Finishing Varnishes, because they can be used on all our Chroma paint brands, Atelier Interactive, Jo Sonja’s or Archival Oils. Application of all these varnishes is by brush (a broad house paint brush), and clean up is with mineral spirits. If applying multiple coats, allow 24 hours drying time between applications. Choose from these finishes: Gloss Solvent Finishing Varnish • Apply as is for a full gloss, usually one coat. To reduce gloss add Invisible Varnish to your taste. Try 2 parts varnish to 1 part Invisible Varnish, up to 1:1 for less sheen. NOTE: The new varnishes have an anti-mould additive which is diluted if you add turpentine, so to maintain the mould protection for tropical conditions dilute with Invisible Varnish instead.

  • Classic Finishing Techniques
    Classic Finishing Techniques By Boyce Gahagan My all-time favorite finish is a mixture of tung oil or boiled linseed oil, and spar varnish, thinned with turpentine, mineral spirits or denatured alcohol. The latter is a thinner for shellac. I have used all three thinners and all have worked well for me. This is a forgiving finish and can be mixed in any proportions. My favorite is equal parts of oil, varnish and thinner. Spar varnish is best for a more durable finish. Brush in on. RUB IT OFF. Apply to a small area. The key to a really good finish with this mixture is to prepare the surface well. There should be no scratches left on the surface before you start to apply a finish of any kind. For the first coat, flood the surface with the mixture and reapply to any areas that appear dry. When the finish becomes tacky, start rubbing with a clean cotton rag. If the rag becomes soaked with finish, change to a clean rag until all of the excess is thoroughly rubbed dry. This is a penetrating mixture and it’s very important that all of the excess is removed. If you wish a deeper finish, wait 24 hours to apply another coat. Subsequent coats of finish go on the same way except that they tack up more quickly and require more rubbing to remove the excess. How fast these coats dry depends on the temperature and humidity and the amount of varnish in the mixture. For small items such as bowls and small spindles, one coat works well and can be waxed after 24 hours.

  • Pine Tar; History and Uses
    Pine Tar; History And Uses Theodore P. Kaye Few visitors to any ship which as been rigged in a traditional manner have left the vessel without experiencing the aroma of pine tar. The aroma produces reactions that are as strong as the scent; few people are ambivalent about its distinctive smell. As professionals engaged in the restoration and maintenance of old ships, we should know not only about this product, but also some of its history. Wood tar has been used by mariners as a preservative for wood and rigging for at least the past six centuries. In the northern parts of Scandinavia, small land owners produced wood tar as a cash crop. This tar was traded for staples and made its way to larger towns and cities for further distribution. In Sweden, it was called "Peasant Tar" or was named for the district from which it came, for example, Lukea Tar or Umea Tar. At first barrels were exported directly from the regions in which they were produced with the region's name burned into the barrel. These regional tars varied in quality and in the type of barrel used to transport it to market. Wood tars from Finland and Russia were seen as inferior to even the lowest grade of Swedish tar which was Haparanda tar. In 1648, the newly formed NorrlSndska TjSrkompaniet (The Wood Tar Company of North Sweden) was granted sole export privileges for the country by the King of Sweden. As Stockholm grew in importance, pine tar trading concentrated at this port and all the barrels were marked "Stockholm Tar".

  • Components and Types of Varnishes
    Components and types of Varnishes Varnish is traditionally a combination of a drying oil, a resin, and a thinner or solvent. However, different types of varnish have different components. After being applied, the film-forming substances in varnishes either harden directly, as soon as the solvent has fully evaporated, or harden after evaporation of the solvent through curing processes, primarily chemical reaction between oils and oxygen from the air (autoxidation) and chemical reactions between components of the varnish. Resin varnishes "dry" by evaporation of the solvent and harden almost immediately upon drying. Acrylic and waterborne varnishes "dry" upon evaporation of the water but will experience an extended curing period. Oil, polyurethane, and epoxy varnishes remain liquid even after evaporation of the solvent but quickly begin to cure, undergoing successive stages from liquid or syrupy, to tacky or sticky, to dry gummy, to "dry to the touch", to hard. Environmental factors such as heat and humidity play a very large role in the drying and curing times of varnishes. In classic varnish the cure rate depends on the type of oil used and, to some extent, on the ratio of oil to resin. The drying and curing time of all varnishes may be sped up by exposure to an energy source such as sunlight, ultraviolet light, or heat. Drying oil There are many different types of drying oils, including linseed oil, tung oil, and walnut oil. These contain high levels of polyunsaturated fatty acids. Drying oils cure through an exothermic reaction between the polyunsaturated portion of the oil and oxygen from the air.

A 4 7 gentle walking loop (1.5 miles) enables 5 8 one to see its history 9 on SGI and within 6 the Plantation Prepared by Jim Mott Turpentine is a natural liquid obtained by the distillation of pine resin obtained from live pine trees. The resin is harvested by cutting the tree bark (so injuring the tree) and collecting the sticky resin that the tree secretes in order to try to heal and protect itself. At the base of the boiling turpentine still, the separated residual liquid (rosin) is then poured off to harden. The rosin can be reheated to make it soft for use (as caulking for example). Turpentine was used medicinally since ancient times, mostly topical but sometimes as internal medicine. it was widely used for abrasions and wounds, and when mixed with animal fat it has been used as a chest rub, or inhaler for nasal and throat ailments. 19th and early 20th century chest rubs, contained turpentine in their formulations. Taken internally (sugar, molasses or honey used to mask the taste) turpentine was injested as treatment for intestinal parasites owing to its alleged antiseptic and diuretic properties. Brush was carefully kept clear from around each tree, owing to fire risk and to watch out for poisonous snakes. The sloped grooves (cat-faces) then cut into the pine bark gave two products, pine resin that slowly dripped into a ‘Herty’ cup and a hardened resin ‘scape’ that solidified on face; both products were scooped into pails, then barrels, and transported away to a large still for boiling and refining.
