1. Why we need Process Control ? Every Chemical Process requires conversion of feed material to product using different chemical and physical operations. Strong need to control processes for more efficiency and economically viability has arose due to stronger business competition, tougher environmental and safety regulations and rapidly changing technological trends. Process Control plays a crucial task in deciding the product quality and has a very high significance in today’s chemical industry. 2. Feedback control: To compensate the effect of the disturbance by measuring the controlled variable (CV) and then considering the difference for control.Feedback control is the most common used in the industries because the disturbances are basically unpredictable. However, feed-forward control is sometimes useful in some special cases. 3. Benefits of Process Control Improves plant performance by reducing the variation of the key variables.
