【摘要】 在试验室用NH₄H₂PO₄和（NH₄）₂HPO₄组成的缓冲溶液,进行琉酸厂尾气脱硫的模拟试验,考察了吸收液中NH₄H₂PO₄浓度、NH₄H₂PO₄/（NH₄）₂HPO₄值、SO₂含量、吸收温度和液气比等因素对SO₂脱除率的影响,并进行了含SO₂富液的解吸工艺条件试验。更多还原

【Abstract】 Laboratory experiments on SO2 absorption by buffer solution of NH4H2PO4- (NH4)2HPO4 were carried out for modelling tail gas desulphur- ization in H2SO4 plants. The effects of NH4H2PO4 concentration, ratio of NH4H2PO4 to (NH4)2HPO4 SO2 content, absorption temperature and liquid to gas ratio on SO2 removal were examined and the operation conditions for regeneration of SO2-containing rich solution were tested.更多还原
