Evaluation of Cogeneration Potential for a Sulphuric Acid Recovery (SAR) Plant

Abstract

Utilisation of excess high-grade heat is useful in creating value-added opportunities in a process. In this technical note, cogeneration of steam and power through combined heat and power (CHP) scheme was evaluated for a sulphur acid recovery (SAR) plant based in the UK. The evaluation was performed using a recently established automated targeting model (ATM). Due to inconsistent feed stream condition, the establishment of relationship between the economic feature and the feed stream concentration is essential in assisting the plant authority in understanding the overall performance of the CHP scheme in the SAR plant.
