©  Copyright 2013 Chemical Engineering  Chemical engineers apply the principles of chemistry, biology, and physics  to solve problems. These problems involve the production or use of  chemicals, fuel, drugs, food, and many other products. They design  processes and equipment for large-scale safe and sustainable  manufacturing, plan and test methods of manufacturing products and  treating byproducts, and supervise production.  Gas processing Natural gas, as it is used by consumers, is much different from the  natural gas that is brought from underground up to the wellhead.  Although the processing of natural gas is in many respects less  complicated than the processing and refining of crude oil, it is equally  as necessary before its use by end users.  Education Engineering education is the activity of teaching knowledge and  principles related to the professional practice of engineering. It  includes the initial education for becoming an engineer and any  advanced education and specializations that follow. Engineering  education is typically accompanied by additional examinations and  supervised training as the requirements for a professional engineering  license.   Nanoscience Nanoscience is an interdisciplinary field of science which has its early beginnings in the 1980s. Chemical Engineering Origins of chemical engineering can be traced almost exclusively to the first half of the  19th Century in Germany. Industrial chemistry, the forerunner of chemical  engineering, originated from laboratories and became an important field of research at  many universities during the this Century.  The first chemical engineering course was given at the University of Manchester in  1887 by George E. Davis in the form of twelve lectures covering various aspects of  industrial chemical practice. This field includes a large variety of industries in the oil  and gas, Petroleum, polymer, food and etc.  Discovery of oil and gas by scientists and various applications of these resources in  different areas, reveal the importance of the chemical engineering more than before.  Due to the existence of oil and gas reservoirs in Iran and the ability to convert them  into chemicals and petrochemical products and the importance of environmental  pollution and process control, training of chemical engineers is an important subject in  Iran.   Chemical Engineering & Gas Processing Chemical Engineering & Gas Processing
