It is important to learn more about how to measure filtration time of activated bleaching earth. The filtration time taken is calculated as the amount of time taken when oil is strained through the fuller’s earth. This fuller’s earth normally has a thickness of five millimeters. There are several good reasons why it pays to find out more about how to measure filtration time of activated bleaching earth. The result of the filtration process will make it easier to determine whether the fuller’s earth is smooth or too light.
In case the fuller’s earth is too smooth it means that this smoothness of extra lightness can cause problems in the oil refinery process. These problems include taking too much time and not being effective as well as causing a jam. Therefore, before doing anything else it is important to find out more about how to measure filtration time of activated bleaching earth.
The first step in this regard is to fill a laboratory measuring glass with about fifty milliliters of fuller’s earth. The next step involves filling about five grams of fuller’s earth into the laboratory measuring glass. Next, stir the fuller’s earth and the crude palm oil in a continuous manner and ensure that this mixture is heated to a temperature of about one hundred degrees Celsius. Allow five minutes for the mixture to remain at this desired temperature.
Take the mixture and pour it into the Filter funnel which in turn should be coated with filter paper that is three centimeters in diameter. Make sure that the activated bleaching earth has a thickness of five millimeters at the filter paper. Take a stopwatch and then start counting all the drops that fall until it achieves a volume of ten milliliters.
It is important to understand that fuller’s earth that is of a good quality will have a filtration time of between one and two minutes. If the quality of fuller’s earth is bad then the filtration time will be more than two minutes.
These are basically the steps that you need to take in order to learn how to measure filtration time of activated bleaching earth. Be sure to use the correct laboratory measuring glass and also make sure that you use the correct amount of crude palm oil. It is also important to fill five grams of fuller’s earth into the laboratory measuring glass.
