Achieved environmental benefits

4.5.3.8.3 获得环境效益

•Reduction of the overall pollutant load released into air compared to a typical semi-wet process.

与典型半干法工艺相比,该工艺可以减少排放到空气中的污染物总量。

•Reduction of the quantity of residues generated thanks to improved stoichiometry compared to reaching the same removal rate with a semi-wet process alone.

与半干法工艺相比,达到同样的去除率,该工艺因为改进(减少)了吸收剂的化学计量比而减少了副产物的产生量。

Environmental performance and operational data

4.5.3.8.4 排放性能和运行数据

Reported removal efficiencies are > 98 % for SO2 and > 99 % for HCl.

报告称该工艺的SO2的去除效率大于98%,HCL的去除率大于99%。

Reported advantages are:

报告称该工艺的优势在于:

•constant operation of the milk of lime preparation;

石灰浆制备系统可以恒定运行;

•fast and accurate response of the DSI to peak pollutant loads;

干粉喷射工艺对峰值污染物负荷出现的反应快速而有效;

•redundancy of equipment for maintenance purposes;

从维护角度而言,多了备用设备;(就是半干法维护时候,还有干法还可以顶一下,有了备用系数)

•reduction of total reagent consumption (at equal acid gas removal rate) compared to the semi-wet process alone.

与单独使用半干法工艺相比(基于相同的酸性气体去除率为前提),减少了吸收剂的消耗总量。

Cross-media effects

4.5.3.8.5 跨介质影响(增加的能源消耗或其他影响)

Since an overall reduction in the use of reagents compared to the use of SDA alone is reported at the same pollutant removal rate, no cross-media effects are expected.

报告称,在相同的污染物去除率下,与单独使用半干法工艺相比其吸收剂使用总量减少了,因此预计没有跨介质影响。

Technical considerations relevant to applicability

4.5.3.8.6 技术适用性的考虑

The technique is applicable to new plants and to existing plants using SDA as the FGC process.

该技术适用于新厂建设和使用SDA半干法烟气净化工艺的老厂改造。

Economics

4.5.3.8.7 经济因素

Investment costs are EUR 100 000–200 000 for a DSI system.

干式吸收及直喷系统的投资成本在10万-20万欧元。

Operating costs, including maintenance and energy costs for the conveying system and reagent costs (1 kg hydrated lime per tonne of waste) for DSI, are EUR 0.17–0.29 per tonne of waste.

运行成本,包括干式吸收剂直喷系统维护成本,输送系统的能源消耗成本,吸收剂成本(吨垃圾1公斤消石灰消耗量),总计为0.17-0.29欧元吨垃圾。

Avoided operating costs by reducing reagent consumption in the SDA unit are EUR 0.33–0.38 per tonne of waste, based on reducing lime consumption from 10 kg to 7.5 kg per tonne of waste.

通过半干法+干法工艺实现比单独使用半干法工艺,从而将石灰消耗量从10公斤/吨垃圾减少到7.5公斤/吨垃圾,这减少半干法系统的吸收剂消耗成本是0.33-0.38欧元/吨垃圾。

Driving force for implementation

4.5.3.8.8 实施动力(该技术的优势)

•As a retrofit, to enable a plant fitted with SDA to further reduce emission levels.

作为技改技术,可以是装有SDA半干法工艺的焚烧厂进一步提高其污染物控制排放水平。

•Allowance of increased input loads of acidic pollutants in the waste.

可以焚烧酸性污染物含量更高的废弃物。

•Savings in operating costs.

省下了运行成本。(应该是吸收剂达到同等脱除率时,总耗量减少。)

4.5.3.9 酸性气体检测在烟气净化工艺中的优化

Description

4.5.3.9.1 说明

By using fast-response HCl, SO2, and possibly also HF monitoring upstream and/or downstream of dry and semi-wet FGC systems, it is possible to adjust the operation of the FGC system so that the quantity of alkaline reagent used is optimised for the emission set point of the operation.

使用在干法或半干法烟气净化系统的上游和/或下游设置的快速反馈的HCL,SO2以及HF在线监测信号,可以调节烟气净化系统的操作,这样碱性吸收剂的使用量可以根据操作的设置的排放值来进行优化(减少)。
