摘要
以H2S和空气模拟含硫工业气体,以错流旋转填料床为脱硫设备,采用湿式氧化法进行脱硫实验。考察了气/液体积比、气体流量、超重力因子、Na2CO3浓度、原料气中H2S含量等工艺参数对脱硫率和气相总体积传质系数的影响规律。研究结果表明,在气液接触时间小于1s的情况下,脱硫率达到95%以上。错流旋转填料床湿式氧化法脱硫工艺可实现快速、高效脱硫,且脱硫设备体积小、操作弹性大、节能降耗,具有工业化应用潜力。
A wet oxidation method,in which a mixture of hydrogen sulfide and air was employed to play a role of sulfur-containing industrial gases,was carried out to study removal of hydrogen sulfide in a cross-flow rotating packed bed.The influences of gas/liquid volume ratio,gas flow rate,high gravity factor,concentration of sodium carbonate and hydrogen sulfide content in feed gas on H2S removal efficiency and gas-phase overall volumetric mass transfer coefficients were investigated in details.It was illustrated that H2S removal efficiency was more than 95% and the contact time between gas and liquid was less than 1 s.Further,such a cross-flow rotating packed bed desulphurization method showed a potential industrial application due to its great advantages of smaller volume,higher desulphurization efficiency,lower liquid/gas volume ratio,larger operating flexibility,lower energy consumption,etc..
