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.
