PINCH ANALYSIS ON HOT AND COLD STREAMS OF AMMONIA PLANT FOR HEAT RECOVERY

Abstract

The aim of this study is to investigate the use of pinch analysis techniques to improve heat recovery in an ammonia production plant. In order to successfully navigate the complicated chemical processes involved in the manufacture of ammonia, precise temperature control is required. Pinch analysis is a methodical way to reduce energy use in plants by identifying locations that are ready for heat integration and improvements in operational efficiency. Finding the "pinch point," or the crucial intersection where heat availability becomes most limited, is essential to this research. Through identification of this critical point, the research enables targeted process adjustments and the tactical implementation of heat exchange networks to maximize energy recovery and reuse. The project aims to increase the overall sustainability quotient of ammonia production, reduce environmental impact, and estimate possible energy savings through thorough analysis. Nevertheless, the empirical results show that the plant is operating at maximum efficiency and that there are no obvious opportunities to save further money. Notably, flue gas emissions are kept at levels that are beneficial to the environment, and the convective portion of the operation runs at maximum efficiency, highlighting the plant's commitment to optimal conditions.
