Advanced process control (APC) is a computer software that optimizes the process by collecting real-time data. It improves plant reliability, optimizes feedstock use, enhances safety and product quality and automatically adjusts the operation of the ammonia plant, replacing minute to minute control by operators. There are optimization potentials with advanced process control in almost all process steps of an ammonia plant. APC increases production by identifying capacity constraints thereby enabling the plant to operate as close as possible to the plant’s capacity. Energy consumption is reduced as maximizing production typically lowers the energy use per tonne of product. 

This measure is applicable for all feedstocks and for both retrofit and new plants.
