propene (C3H6). The term stems from isopropyl benzene or cumene (C6H5-CH(CH3)2), the intermediate material during the process. This process illustrates Chemical engineering is the application of science, mathematics and economics to the process of converting raw materials or chemicals into more useful or valuable forms. The term economics is important here. Chemical Engineering largely involves the design and maintenance of chemical processes for large-scale manufacture. Chemical engineers in this...
