Automated Control and Monitoring Systems for Technological Processes in Ammonium Nitrate Production / Leonid Dovgalov, Olena Ushakova, Sergii Shylin // Хімія та хімічні технології : матеріали ІІI Міжнародної конференції молодих вчених CCT-2013, 21–23 листопада 2013 року, Україна, Львів / Національний університет "Львівська політехніка". – Львів : Видавництво Львівської політехніки, 2011. – С. 176–177. – (4-й Міжнародний молодіжний фестиваль науки "Litteris et Artibus"). – Bibliography: 6 titles.https://ena.lpnu.ua/handle/ntb/27060Two automated control and monitoring systems for the neutralization process in ammonium nitrate production have been elaborated. The methods are based on the dependence of measuring electrode potential on the concentration of nitric acid and ammonia in a neutralizer. The systems have been shown to be efficient in wide concentration and temperature ranges. In this paper, the monitoring system for the concentration of water in ammonium nitrate melt has been also presented. The proposed systems has been tested in industry and implemented into production.enautomated controlredox potentialneutralizerammonium nitrateconcentration sensorsolidificationecofriendly productionArticle
