Temperature control is very vital for processes that induce very high temperatures. Thus the need for tight control to prevent undesired production, or reactor burst. Process control is somehow shared between the fields of chemical engineering (more focus to process), and control engineering (more focus to control), and a mid point is to be reached by both sides to achieve the plant and production requirements, and also to maintain the system stable. Two control schemes are to be explored, PID control and neuro-control. The first one is widely used in all of industry sectors, especially process control. The later one is still a field of discovery and exploration, as all focus is there now to make intelligent systems the new substitutes for the conventional control systems. The system under the study is the non-isothermal CSTR with irreversible reaction A~B. The control scheme using the coolant flow showed that it is more efficient in heat removal and maintaining the system stable and under control, at the same time achieving the economic goal of highest productivity. Another scheme to be in touch is the hybrid control, where by different schemes are combined to compensate for each other, reaching an optimal control structure. For Further improvement to the system design, more disturbances to be included, and more complex processing units are to be tested using the controller schemes proposed. Experimental work is also an advantage to verilY the simulations of the system and the controllers.
