Optimization of Ammonia Recovery Unit at FFC Plant-1

Abstract

In the past 30 years, the chemical industry has been the subject of notable changes due to higher demands, and increasing production and operational costs. Now, there is great competition in product pricing and quality in local and global markets. As a result, it has become imperative for chemical industries to focus on optimization of industrial units and processes. Chemical processes have to be made as efficient as physically possible and within the reasonable constraints. Chemical engineers are determined to find better-operating strategies and processes controls. The current situation of Purge Gas Recovery Section at FFC Plant-1 offers an opportunity for energy optimization of the Ammonia Recovery Unit. The main idea behind the study is to reduce energy consumption for the plant and make a positive contribution towards its profitability. Therefore, this study focused on the statistical determination of optimum operating parameters for a purge gas Ammonia separating unit at FFC-1. In order to reduce the overall energy requirement of the unit and reduce production cost of NH3 required for Urea; ultimately increasing profitability for FFC.
