What is Chemical Engineering

Chemical Engineering  can be defined as the discipline that deals with the transformation of processes into  useful forms that can be used directly or indirectly by mankind.  The processes can be either natural (e.g. fuels, saline water,...etc) or   industrial (e.g. chemicals, biochemicals,...etc). The transformation of these processes can take several ways. It can be chemical, physical or biological. For this reasons the chemical engineering is   a broad discipline.   Chemical engineer  has a  broad  knowledge of  mathematics, physics, chemistry and biology.  Our modern life would not have been  the way it is   without chemical engineering.   Chemical engineers  produce petrochemicals  from crude oil. They produce gasoline for our cars, plastics that is used in  our daily life, fertilizers used in the crops and fibers for our clothes. Chemical engineers produce fresh water from saline water in our desert country.  They produce the processed food  we eat , the cement for our buildings and they work closely with the pharmaceutical industry to produce drugs for our health. In  developing all these useful products, chemical engineering always  takes into consideration   to minimize their cost so as to make these products available at the lowest price to the consumer. The chemical engineer also designs  processes so as  to minimize its harmful effects on the environment. Chemical engineers are therefore the leaders to develop   Green Engineering.
