摘    要:对皮江法炼镁工艺和真空碳热还原法炼镁工艺进行了生命周期评价研究。评价过程以1 t镁锭为功能单位,研究了包括原料开采、物料制备、物料耗损、能源生产、污染排放等过程的环境负荷以及能源消耗。在得出生命周期评价相关参数的基础上,对皮江法炼镁与真空碳热法炼镁在资源与能源消耗、气型污染物的排放和对环境的影响方面进行了比较,明确了上述两种不同工艺过程各自的环境负荷和能源消耗特点。通过比较,碳热法炼镁工艺较皮江法在资源节约、节能减排、环境保护及可持续发展方面有明显优势。

关 键 词:镁;镁冶炼;皮江法;真空碳热还原法;生命周期评价

Abstract:Life cycle assessments (LCA) of magnesium smelting process by Pidgeon method and vacuum carbothermic reduction method were carried out using 1 t magnesium ingot as functional unit to study environmental load and energy consumption of processes including raw material mining, material preparation, material consumption, energy production, and pollution discharge. On the basis of deriving relevant parameters of LCA, Pidgeon process and vacuum carbothermal reduction method were compared in terms of resource and energy consumption, gaseous pollutant emission and environmental impact. Respective environmental load and energy consumption characteristics of two process were clarified. By comparison, carbothermic reduction method has obvious advantages over Pidgeon process in terms of resource saving, energy conservation, environmental protection and sustainable development.
Keywords:magnesium   magnesium smelting   Pidgeon process   vacuum carbothermic reduction method   life cycle assessment (LCA)
