Main factors affect the refined oil yield: 1‚ the alkali refining loss (1) for removal of colloid in hair oil‚ free fatty acid‚ moisture‚ impurities and other form of loss; (2) in the process caused by the loss of neutral oil saponification‚ emulsification; (3) theoretical calculation formula: alkali refining losses = 0.2 + 1.25 x (FFA % % + water + phosphatide content % % + 0.3% + impurities) 2‚ decoloring loss mainly for adsorption bleaching waste clay in oil absorption caused by the loss

Environmental Pollution Environment means our surroundings. It consists of air‚ water‚ soil and other natural resources‚ that make our earth habitable for us. All the elements of environment are well proportioned and depend upon each other. This characteristic of environment is called ecosystem. If any element of it is destroyed‚ it affects all other elements. So for our existence we must not destroy the ecological balance. But consciously or unconsciously we are damaging vital elements

2013 Science Research Project: The Effect of Calcium on Plant Growth Problem Statement What affect do various amounts (0 mg‚ 300 mg‚ 600 mg) of Calcium added to Vigna unguiculata (black eyed pea plants) once a week have on the overall growth (height‚ number of leaves‚ number of pods) over a 30 day period of time? Research Hypothesis If various amounts (0 mg‚ 300 mg‚ 600 mg) of Calcium are added to Vigna unguiculata (black eyed pea plants) once a week‚ then those plants receiving 300 mg of Calcium

This reaction is highly exothermic and a lot of heat liberated during the reaction. This heat is sufficient to burn a spirit lamp. While doing this experiment it is necessary to use small quantities of the reagents because this reaction can be explosive. 2KMnO4 + 2 H2SO4 → 2 KHSO4 + Mn2O7 + H2O These activities show that different substances catch fire at a different temperature. The lowest temperature at which a substance catch fire is called its ignition temperature. Combustible substances do

How To Grow A Garden It takes a lot of time and hard work to grow a garden. First you would have to start out small. You don’t want to bit off more than you can chew‚ or hoe. Like ‚ if you plant a huge garden‚ you’ll wish that you didn’t because of the hard work. Next‚ you must choose a location that receive as much sunlight as possible throughout the day. After you have located a spot to grow your garden‚ you should examine the soil. You will want to see if the ground is rich in top soil. Sometimes

Speed of Decomposition and Its Factors Purpose The term decomposition is the process of breaking down dead organisms to reuse them. Decomposition allows nutrients in organisms to become free after they die or have become old and they are ready to be used by living plants and animals for their growth. Without decomposition useful nutrients would remain locked inside of a dead organism and it would be very difficult for new life to grow. Most of the nutrients that are essential for the plants

Three major causes of soil erosion There are three causes of soil erosion over cultivation‚ overgrazing‚ and deforestation. All of these causes can be corrected in different ways. Over cultivation is when the land is repeatedly tiling and producing crops faster than the soil can restore resulting in a decrease in the soil value and productivity. One of the ways that over cultivation can be corrected is by a technique called no-till agriculture. No-till agriculture is a procedure where chemicals
