摘要

摘要: 镁砂生产过程会产生一氧化碳（CO）排放，但当前针对该过程CO排放因子的公开实测数据长期缺乏，制约了行业排放核算与减排评估的准确性。为弥补典型镁砂生产工艺CO排放基础数据不足，研究选取中国辽宁省鞍山市3家代表性镁砂生产企业，覆盖“轻烧-压球-竖窑重烧”两段式煅烧、“悬浮煅烧-重烧烧结”和电弧炉熔融三类典型工艺路线。在企业未配置CO在线监测模块的条件下，构建了人工监测与烟气连续排放监测系统（CEMS）常规指标耦合的估算方法，通过建立CO与氮氧化物（NO_x）、颗粒物（PM）浓度特征比值关系，并结合全年在线监测数据，核算产品CO排放因子。结果表明：两段式煅烧、悬浮煅烧-重烧烧结和电弧炉熔融工艺企业的CO排放因子分别为5.35，5.18，1.40 kg/t，其中电弧炉熔融工艺的排放水平显著低于烧结型工艺。研究提供了镁砂行业企业级CO实测参数，填补了典型工艺路线排放因子基础数据空白，并提出了适用于CO在线监测缺失条件下的排放因子估算方法，可为相关行业污染物排放核算与排放清单编制提供参考。

Abstract: Magnesia production processes generate carbon monoxide （CO） emissions； however， publicly available measured data on CO emission factors for these processes remain scarce， which constrains the accuracy of emission accounting and mitigation assessment in the industry. To address the lack of basic data on CO emissions from typical magnesia production processes， this study selected three representative magnesia-producing enterprises in Anshan， Liaoning Province， China， covering three typical technological routes： the two-stage calcination process （“light burning-briquetting-shaft kiln dead burning”）， the “suspension calcination-dead burning sintering” process， and the electric arc furnace melting process. Under the condition that enterprises were not equipped with online CO monitoring modules， an estimation approach coupling manual measurements with conventional indicators from the Continuous Emission Monitoring System （CEMS） was developed. By establishing characteristic concentration ratios between CO and nitrogen oxides （NO _x ） or particulate matter （PM）， and combining them with annual CEMS monitoring data， product-level CO emission factors were calculated. The results showed that the CO emission factors for the two-stage calcination process， the suspension calcination–dead burning sintering process， and the electric arc furnace melting process were 5.35， 5.18， and 1.40 kg/t， respectively， among which the emission level of the electric arc furnace melting process was significantly lower than that of sintering-based processes. This study provides enterprise-level measured CO parameters for the magnesia industry， filling the data gap in emission factors for typical technological routes. It also proposes an emission factor estimation method applicable under conditions where online CO monitoring data are unavailable， which can provide methodological support for pollutant emission accounting and emission inventory development in similar data-constrained industries.
