摘 要: 在推演氧化鋁生產(chǎn)綜合能耗基本計(jì)算式的基礎(chǔ)上， 提出了氧化鋁生產(chǎn)企業(yè)剖析綜合能耗的e-p分析法。并以某氧化鋁廠1995~2000年的生產(chǎn)和能源消耗統(tǒng)計(jì)數(shù)據(jù)為依據(jù)， 分析了工序能耗變化和折合比變化對(duì)綜合能耗的影響。認(rèn)為為了降低氧化鋁生產(chǎn)綜合能耗， 一是要降低各工序的折合比， 二要降低各工序能耗。 并指出為了降低各工序的折合比， 需要優(yōu)化生產(chǎn)工藝結(jié)構(gòu)， 加大拜耳法及拜耳法中管道化的比例，通過選礦法來提高礦石的品位。

Abstract:On the basis of analyzing the formula of the comprehensive energy consumption for per ton of alumina, the e-p method is put forward. The influence of the change of the unit process energy intensity and the alumina-process product-ratios on the comprehensive energy intensity is analyzed, based on the statistical data of an aluminium corporation in the period of 1995~2000. The conclusion is that it is necessary to cut down both the unit process energy intensity and the alumina-process product-ratios in order to decrease the comprehensive energy intensity for per ton of alumina, which is to be taken as a future policy for energy saving. In order to decrease the alumina-process product-ratios, it is necessary to optimize the process and enhance the grade of bauxite by ore dressing.
