Abstract

SELECTIVE HYDROGENATION IS USED TO REDUCE ACETYLENE CONCENTRATION LESS THAN 1 PPM DUE TO POISONS THE CATALYSTS IN POLYMERIZATION PLANTS. THE CATALYSTS HAVE TO REGENERATE DUE TO GREEN OIL FORMATION DURING HYDROGENATION. CLOSE MONITORING OF THE TWO REGENERATION CYCLES IN AN OLEFINE PLANT IN JAM PETROCHEMICAL COMPLEX, HAVE REVEALED COMPLICATIONS THAT CAUSED A DRAMATIC REDUCTION IN CATALYST LIFETIME AND ALSO DISRUPTED THE TEMPERATURE PROFILE IN THE REACTOR OVERTIME. INSTEAD OF CONVENTIONAL CONFIGURATION AFTER VALIDATION OF THE DYNAMIC MODEL A NEW CONFIGURATION WAS PROPOSED, SIMULATED AND CONSTRACTED. AS A RESULT, THE REGENERATION PERIOD DECREASES SIGNIFICANTLY BY 28 H.
