Acron to Integrate All Ammonia Units into a Single Information Network

Acron Group, a leading vertically integrated mineral fertiliser producer in Russia and globally, is upgrading its ammonia operations in Veliky Novgorod.

Novgorod-based Acron is undergoing scheduled upgrades to the second ammonia unit and liquid ammonia warehouses to integrate all the ammonia units into a single information network. 

Kirill Zabolotsky, Acron’s Lead Engineer and Deputy Chief Instrumentation Engineer for automatic process control systems, explained that these upgrades are required due to depreciation of the existing controllers of the process control system that process signals and send them to the control panel, which have been in operation for 20 years. New control devices manufactured by Honeywell have been already purchased and will be installed during the current overhaul. 

An additional controller, new stations and a backup server will be installed at the liquid ammonia warehouses. The existing system was put into operation in 2008, and since that time safety requirements have become significantly more stringent. 

“Continuous ammonia supplies to key customers and production targets delivery depend on sustainable warehouse operations”, Zabolotsky said. “These upgrades will increase the system’s reliability and extend its service life. We plan to install the new equipment later this summer”. 

Acron’s ammonia units have many common parameters affecting each other’s operation, and integration of all four units and warehouses into a single information network using distributed server architecture will improve their performance. Process information will be transmitted through fibre-optic cables without limiting the number of signals, and the integration of all systems into a local network will streamline the data exchange. 

Honeywell specialists, Acron’s instrumentation and automation personnel and specialised contractors will work together to set up the new equipment.
