PJSC “Azot” (Cherkasy) invested UAH 18 million in modernization of nitric acid production
PJSC “Azot” (Cherkasy), a member of Group DF nitrogen business, has completed the modernization of M-5 workshop that produces weak nitric acid, a raw material for the production of ammonium nitrate.
The modernization entailed a large-scale reconstruction of the technological process control system in the department No. 1, i.e. the outdated control and automation system was completely replaced with a modern distributed technological process control system using microprocessor technology.
Following the commissioning, the new distributed control system (DCS) was put into operation in department No. 1, where three units are producing the weak nitric acid.
The reconstruction included not only the installation of new devices, laying cables, the repair of adjacent office and utility rooms. Earlier, a new DCS control system was implemented in department No. 2, where the weak nitric acid is produced on 7 units.
The installed capacity of all 10 units at M-5 workshop is 3,600 tons of weak nitric acid per day. The company’s production plans for 2021 envision stable and sustainable operations of 9 units. Another unit, following the capital repairs, will become a spare one, since the process of the nitric acid production entails scheduled repairs on all units in turns.
