Abstract |
|
This paper deals with the design of a shutdown controller for a Sphere tank in oil refinery using Programmable Logic Controller (PLC). PLCs are sequential control systems which are used to implement safety interlock system in industrial plants. The sphere tanks are used to store flammable products like LPG and must be isolated in case of fire or gas leakage PLC are switch type devices we, closing all the inlet and outlet (ROVs) valves. According to predefined conditions, the safety instruments located both at the field and at the console will function. This system also includes gas leakage detection. Keywords: Sphere, Programmable logic controller (PLC), shutdown, Liquefied Petroleum Gas (LPG), Remote Operating Valves (ROV). |
