Abstract: The principles and knowledge of chemical engineering has been applied into many processing fields such as metallurgy, materials, energy source, environment, bioengineering and so on. Therefore the chemical engineering could be renamed as process engineering. The present theories on heat transfer, mass transfer, momentum transfer, and chemical reaction for chemical engineering are still the basic theories for process engineering. However, it is inevitable and possible to produce new basic theories for process engineering. Along with the fast development of computer technology and measurement instruments, the research range of process engineering is extended to cover from observation and prediction of the micro-scale structure and interface to the system integration of the macro-scale equipment and plant, which refers to the structure, interface, and multi-scale issues. The methodology of averaging, which neglects the influences of the heterogeneous multi-scale structure and interface, should be replaced by the multi-scale methodology. In addition the shortage of energy resource and natural resources, the pollution of the environment have become the challenging problems facing to the mankind. The green operation and optimal integration of process engineering have become focal points of researchers. The principles and methods on the structure, interface, multi-scale, green operation, and optimal integration of process engineering should be the contents of the new basic theories for process engineering.
