Enumeration of Supervisory Control and Data Acquisition Systems for Pneumatic Actuated Knife Gate Valves with Fail Safe Systems

Any flow line has a specific intent. As a result of accurate input of various parameters like flow rate, flow temperature and so on, the intended chemical reactions or other output actions can be carried out successfully. Energy is a basic requirement to initiate, sustain and conclude a flow. This energy can be in various forms and it is a system requirement to supply continuous energy to ensure energy conversion with minimum entropy change. While planning a project, these considerations need greater attention as a part of risk assessment considering unlikely events like failure of electrical power or any other source of energy. This paves way to design of systems considering fail safe conditions. Supervisory control and data acquisition systems can add an additional dimension to the effectiveness of these systems. This paper intends to highlight enumeration of Supervisory Control And Data Acquisition system for various fail safe systems considering various conditions. A number of possibilities emerging from the three types of failures namely electric current, air supply and a combination of both have been considered to satisfy the three fail safe conditions of fail to open, fail to close and fail to stay put. A conclusion shall be drawn thereafter to get a generalized idea of the design of Supervisory Control And Data Acquisition systems for fail safe systems.
