硫酸、盐酸和液体烧碱,都具有强烈的腐蚀性,要用专门材料制作包装容器和输送设备。因此,选择合理的输送方式,对供需双方的经济效益都有很大关系。现以北京、上海两市两酸一碱的生产、使用及输送情况为例,谈些看法。目前,北京市所用的工业硫酸基本上由北京染料厂生产供应。1984年供应量约59,000吨,其中由染料厂直接供货的占92.7%,由北京市化轻公司酸苯供 Sulfuric acid, hydrochloric acid and liquid caustic soda all have strong corrosiveness, and use special materials to make packaging containers and conveying equipment. Therefore, the choice of a reasonable mode of transport, both the economic benefits of both supply and demand have a great relationship. Now Beijing, Shanghai, two cities of acid and alkali production, use and delivery of the case, for example. At present, the industrial sulfuric acid used in Beijing is basically produced and supplied by Beijing Dyeing Factory. Supply of about 59,000 tons in 1984, of which 92.7% of the direct supply by the dye factory by the Beijing Chemical Light benzene acid company
