Process engineering today is concerned with the understanding and development of systematic procedures for design and optimal operation and control of the chemical process systems. This work motivated by the need to provide a more flexible than existing approaches framework for changes in chemical process engineering in particular, and for predicting the behavior of process systems in general. Integrated method of the process systems development make possible seeking out the most adequate model for simulation of real process design and optimization, that leads to improving current and development a new processes. The study state plant simulation model and dynamic simulation model make significant tools for observation behavior of the process. Comparative study of different processes can established more concurrent process alternatives.
