OPTIMIZATION OF STEAM AND ELECTRICAL ENERGY CONSUMPTION IN AN OPERATIONAL PETROCHEMICAL INDUSTRIAL ENVIRONMENT: A COMPREHENSIVE CASE STUDY OF INDORAMA ELEME PETROCHEMICAL LIMITED

Abstract: The efficient use of utilities (electric energy, steam, and water) constitutes today's major problem in ensuring industry competitiveness and sustainability. The proposed study focuses on lowering the cost of steam and power generation at a petrochemical industry that uses a co-generation system to generate both electricity and steam. In this scenario, there is a trade-off between work and heat supply that cannot be easily characterized by heuristics or localized control loops. The use of an optimization model is provided based on the necessities of energy demands, and it is easily exposed the landscape that minimizes power and high-pressure steam level generation. There was a potential economy of 46 t/h in the generation of steam in boilers and a decrease of 6 MW in electric power usage.
