摘 要：近年來，全球變暖已成為全世界最關心的環保問題，造成全球變暖的主要原因是大量的溫室氣體產生。每當大氣中CO2濃度增加1倍時，氣溫會上升4—6℃，不斷演化使人類所賴以生存的生態和社會經濟系統受到極大的危害。人類只有一個地球，減少溫室氣體排放已成為當今國際社會所面臨的一個刻不容緩的問題了。

　　　鋼鐵企業生產主要流程有：煉焦生產、燒結生產、高爐生產、轉爐生產、連鑄生產和熱軋生產，分長流程和短流程兩種，溫室氣體的排放與所采用的流程密切相關，長短流程排放量之比約為4.8:1。溫室氣體的排放主要取決于鋼鐵生產流程中鐵的來源：使用回收鐵和廢鋼煉鋼比直接用鐵礦還原煉鋼需要更少的能量和碳。

　　　本課題主要從研究背景及意義，國際通行方法，鋼鐵生產過程中的碳計量以及實例分析等方面進行介紹。主要內容包括：溫室氣體對氣候的影響，溫室氣體排放現狀，溫室氣體減排措施，CO2捕集與存儲技術（CCS）發展概況；了解溫室氣體排放計量意義與基本方法；掌握鋼鐵生產流程，并確定鋼鐵生產過程溫室氣體排放計量方法?；谝陨蟽牲c，對鋼鐵企業特定的實際運行過程進行溫室氣體排放計量。

關鍵詞：溫室氣體、鋼鐵生產碳的計量、溫室氣體的減排

Abstract：In the recent years, global warming has become the world's most concern the environmental protection question, and cause the main cause of global warming is a lot of greenhouse gases generated. Whenever atmospheric CO2 concentration, double temperatures will rise when 4 to 6 ℃, and constantly evolution of what human survival ecological and social economic system is the enormous harm. There is only one earth, reduce greenhouse gas emissions have become today's international society faces a urgent question.

　　　Steel enterprises, the production of major process are: coking production, sintering production, blast furnace production, converter production, continous casting production and hot-rolling production, long process and short process runs two, greenhouse gas emissions and the process is closely related to the ratio of the length of flow approximately 4.8 emissions: 1. Greenhouse gas emissions mainly depends on the source of iron and steel production process and scrap iron recycle: use of steelmaking with iron ore than direct reduction steelmaking require less energy and carbon.

　　　This topic contents include: a greenhouse gas effects on climate situation, greenhouse gas emissions, greenhouse gas measures, CO2 capture and storage technology development survey (CCS); Understand greenhouse gas emissions measurement significance and basic methods; Master steel production processes, and determined the steel production process greenhouse gas emissions measurement method. Based on the above two points, to steel enterprise specific actual operation process for greenhouse gas emissions measurement.

Keywords: greenhouse gases, carbon steel production of measurement, greenhouse gas emissions
