Industrial Chemical processes
Industrial Chemical Processes Essay Tan Hung Kai Grade 11
In our present world, there are thousands of chemical processes that are being used to produce products that benefits our daily lives. Industrial Chemical processes are used for “transforming raw materials into useful commercial products for society”. (Dr. Philip Britz-Mckibbin Industrial Chemistry: CHEM 2013) Examples of industrial chemical processes include distillation, smelting, disinfection, and Pyro processing. Even today, scientists in our industry continue to find, develop, and create new products with the experimentation of the chemical processes. Without these chemical processes, we would probably not be able to live the way we do today. Today, distillation is one of the most widely used methods worldwide.
Distillation is the separation of mixtures and the removal of all the impurities based on different boiling points required to change the phase of components from the state of liquid to vapor and then back to liquid state. (Anne Marie Helmenstine, Ph.D What is Distillation? About.com Guide) To separate the two different liquids, the liquid with the lower boiling point must be heated with a heat source to just above the boiling point of the first liquid and below the boiling point of the second liquid. For example, let us take water and ethanol that have been mixed together. The boiling point of water is 100 degrees Celsius and the boiling point of ethanol is 78.37 degrees Celsius. (Anne Marie Helmenstine, Ph.D What is Distillation? About.com Guide) If the liquid is heated to 80 degrees Celsius, which is past Ethanol’s boiling point and maintained. Ethanol will change from a liquid state to a gaseous state, but water will not, as it is not yet past its boiling point. The evaporated Ethanol gas will then be condensed by cold water back into a liquid state, also known as the distillate. This will basically separate the 2 liquids. “Repeating this process to help to improve the purity “is
