鼓泡塔中有机酸强化粗颗粒石灰石新型烟气脱硫

对传统石灰石湿法烟气脱硫进行了改进,提出了一种新型烟气脱硫方法,即在鼓泡塔中添加有机酸,采用大颗粒石灰石(210 μm)代替传统的细颗粒石灰石(5～20 μm)进行脱硫.实验在鼓泡搅拌吸收反应器中对比研究了新老两种脱硫工艺.结果表明,当210 μm石灰石浆液中醋酸摩尔浓度达10～30 mmol/L,其脱硫率和石灰石利用率分别为95%和93.5%,均达到甚至优于传统石灰石脱硫结果.实验研究了影响脱硫率的各种因素:添加醋酸浓度、入口SO2浓度、石灰石浆液浓度、气体停留时间以及温度等,并提出添加醋酸促进SO2吸收的机理.运用该新型烟气脱硫方法,可降低电厂的基础投资和运行费用,大大加强系统的稳定性和抗击烟气中SO2波动的能力.

Acid mine drainage attenuation by inhibition of pyrite bioleaching using limestone and olive pomace

The control and inhibition of pyrite bioleaching involved in the generation of acid mine drainage was studied. Inhibition of pyrite bioleaching was performed by varying the pyrite concentration in the medium (substrate inhibition) and/or by addition of limestone (inhibition by pH increase) and olive pomace (inhibition by organic compounds). Inhibition tests of pyrite bioleaching were performed according to a full factorial design with three factors (pyrite, limestone and olive pomace) taken at two levels. Preliminary pyrite bioleaching tests showed the ability of the available inoculum to oxidise the mineral. Subsequently, experimental data for total soluble iron denoted strong inhibition under all the different operating conditions of the factorial design, except when larger pyrite concentrations were used. In particular, inhibition by limestone was due to the increase in pH which negatively affects microorganisms, while inhibition by olive pomace may be related to the antioxidant properties of polyphenols. Interactions among operating conditions were specifically assessed by analysis of variance. Only limestone and/or pomace addition resulted in a significant (95%) diminution of iron extraction.
