墨西哥电力部门的二氧化硫排放量占全国的 75% 以上，造成了经济和健康损害。这些排放主要来自化石燃料的燃烧，而一小部分来自生物质（木材燃料和甘蔗）燃烧排放以及工业过程产生的排放。为此，本研究评估了几种二氧化硫控制方案的减排成本（包括烟气脱硫技术、燃油加氢处理以及用低硫含量燃料替代高硫）。同样，本研究评估了 10 个选定发电厂（墨西哥电力部门 (MEPS) 的主要二氧化硫排放源）中此类方案的实施情况，目的是提出二氧化硫减排解决方案，并估算分析期间相应的减排量、投资和总成本。研究结果表明，最佳二氧化硫减排成本路线可能会减少 41% 的 MEPS 二氧化硫排放量，并且需要的投资和总成本分别为 841 美元和 4.77 亿美元。这意味着只需付出相对较小的努力即可大幅减少国家二氧化硫排放量。
Mexico’s electricity-sector contributes over 75% of national SO2-emissions, causing economic and health damage. These emissions come mostly from the combustion of fossil-fuels, whereas a minor share comes from biomass (wood fuel and sugar cane) burning emissions as well as those produced by industrial processes. For this reason, this study assesses the abatement costs of several SO2-control options (including flue-gas desulphurization technologies, hydrotreatment of fuel oil, and the substitution of high-sulfur by low-sulfur content fuels). Likewise, this study has evaluated the implementation of such options in 10 selected power-plants—the main SO2emitters in the Mexican Electric Power Sector (MEPS)—with the aim of suggesting solutions for SO2-emissions reduction and estimating the corresponding abatement, investment and total costs during the analyzed period. Study’s results indicate that the best SO2-abatement-costs route may account for a reduction of 41% of MEPS SO2-emissions and would require investment and total costs of $841 and $477 million, respectively. This means that an important reduction in the national SO2-emissions may be achieved with a relatively small effort.
