摘要
西利沙蒙公司的废硫酸再生工艺.将酸分解成二氧化硫和水,经净化后,在接触法装置中氧化成三氧化硫,重新生成硫酸。该工艺生成的硫酸是商业级的,其主要缺点是投资和操作费用比浓缩法高。对于不适于浓缩的废酸,采用再生工艺,利用废物生产硫酸,与其他硫酸生产工艺相比,成本上较经济.
Waste acid can be recovered to produce commercial H2SO4 by Siry Chamon process which consists of decomposition of waste acid into SO2 and H2O,gas cleaning,oxidation of SO2 to SO3 and absorption of SO3. The main drawback of the process is its higher investment and operation costs compared to concentration process. However, when waste acid is not suitable for concentration,the process will be economically superior to other sulphuric acid proresses.
