日前,由化学工业第二设计院承担设计的辽阳石油化纤公司11.6万吨/年稀硝酸及4万吨/年浓硝酸装置投产四个月以来运行平稳,经考核达产达标,核心设备“四合一”机组成为国内第一套成功运行的国产化机组,标志着我国硝酸装置已完全实现国产化。此前我国设计的硝酸装置尤其是核心设备一直采用国外设备,投资成本高。化二院此次为辽阳石油化纤公司设计的硝酸装置浓硝酸部分采用硝酸镁法技术,稀硝酸部分则采用了该院改良后的“双加压”法专
Recently, the Liaoyang Petrochemical Company, which is undertaking design by the Second Chemical Industry Design Institute, runs smoothly with 116,000 tons of dilute nitric acid and 40,000 tons of concentrated nitric acid unit put into operation for four months. The core equipment of “ Siheyi ”unit became the first successful operation of the domestic unit, marking China’s nitric acid plant has been fully realized localization. Prior to our design of nitric acid plant, especially the core equipment has been the use of foreign equipment, high investment costs. The Second Hospital of Liaoyang Petrochemical Company for the design of nitric acid plant concentrated nitric acid part of the method using magnesium nitrate, dilute nitric acid is used in the hospital after the improvement of the “double pressurized” law
