Part III of this three-part paper examines steam ReGenerated Heat (RGH) (the residual steam sensible heat in the exhaust) for full (100%) steam-injected cycles. Parts I and II deal with Steam Rates and Steam-Cycle Efficiency respectively for a finite amount of steam injection. The following RGH analysis is based on the same approach used for large-utility steam turbines where one pound of throttle steam is passed through the steam system, and where enthalpy points are determined along the steam path. Accurate analysis of heat input, partial pressure expansion and heat-rejection enthalpy points are computed with steam-table software.

Inherent Problem

Automation of process control in chemical plant is an inspiring application field of mechatronicengineering. In order to understand the complexity of the automation and its application requireknowledges of chemical engineering, mechatronic and other numerous interconnected studies.The background of this paper is an inherent problem of overheating due to lack of level controlsystem. The objective of this research is to control the dynamic process of desired level more tightlywhich is able to stabilize raw material supply into the chemical plant system.The chemical plant is operated within a wide range of feed compositions and flow rates whichmake the process control become difficult. This research uses modelling for efficiency reason andanalyzes the model by PID control algorithm along with its simulations by using Matlab.
