南化集团公司现有两套硫酸生产装置,年产能力32万t,均采用硫铁矿制酸工艺,成本高、污染严重。随着生产发展,自用酸量将达到45万t/a。因此该公司拟利用扬子与金陵石化公司炼油厂副产H_2S废气回收的硫磺资源,采用先进的硫磺制酸工艺,对原五系统与七系统进行技术改造,同时适当扩产,满
Nanhua Group Company has two sets of existing sulfuric acid production plant, annual production capacity of 320,000 t, are using pyrite sulfuric acid technology, high cost and serious pollution. With the development of production, acidity for personal use will reach 450,000 t / a. Therefore, the company plans to utilize the sulfur resources recovered from H_2S waste gas byproducts from the refinery of Yangtze and Jinling Petrochemical Company. The Company will adopt the advanced sulfur-based sulfuric acid technology to carry out technological transformation on the original five systems and seven systems,
