FUZZY LOGIC CONTROL FOR SELECTIVE HYDROGENATION OF ACETYLENE IN ETHYLENE RICH STREAMS USING VISUAL BASIC

Shahid Raza Malik

Abstract


Presence of acetylene is technically disadvantageous in the ethylene rich gas streams from steam crackers. Acetylene tends to polymerize and inactivates the transition metal catalysts, forming highly explosive compounds. The acetylene content has to be selectively reduced to less than one part per million for such streams. The acetylene hydrogenation unit requires stringent control parameters and needs specialized process control techniques for its operation. This study is concerned with application of Fuzzy Logic Control to manipulate and control the process plant with higher precision and greater simplicity. The control program has been written in Visual Basic and entails all major scenarios of work modes for successful hydrogenation of Acetylene.
