Welcome to Milda in this video. I am going to discuss about the industrial requirement in a spot of industrial chemistry course. In this industrial requirement unit, there are three further subunits. First subunit is industrial requirements. Second one is fuels, third one is energy. In the industrial requirement subunit, we are going to discuss about what are the general requirements needed to set up here industry. Say for example, in which place we are going to set up here, industry, what are the requirements for how can we choose their particular place for the industry and then what are the other requirements we need to satisfy to set up here used to. All these things will be discussed in the industrial requirement subunit. In the next subunit is fuel. In the fuels of units, we are going to discuss about three different types of fuels, solid fuels, liquid fuels and gases fuels. So fuel is very much necessary to run the industry. We are going to discuss about these three types of fuels and what are the different sources for the fuels, examples, how to purify the fuels and how to enrich the fuels towards the efficiency of the engines, like motor engines, industrial engines, so on and so forth. Next subunit is energy. Out of fuel we got energy and what are the sources of energy is generally classified into two types, renewable energy sources, non-renewable energy sources. So what are non-renewable energy sources and what are non-renewable energy sources. We are going to discuss about this and finally in this energy subunit, we are going to discuss about how to harvest the energy from the nature, what are the different methods available and advanced methods available to harvest the energy from the nature. All these things will be thoroughly discussed in the fueling one of the industrial
