while doing 的逻辑主语判断

3 while doing 的逻辑主语判断

During the Petrochemical PTA plant upgrade, the production capacity was expanded from 225 Kt/a to 400 Kt/a while achieving a 32% reduction in overall energy consumption.

这句话应该没有语法错误，但是这个while achieving的逻辑主语是哪个呢？

这应该不是一个很好的文体，while 从句的逻辑主语应该指the Petrochemical PTA plant upgrade，后半句这样改写一下会更好：while a 32% reduction in overall energy consumption was achieved.

During the Petrochemical PTA plant upgrade, the production capacity was expanded from 225 Kt/a to 400 Kt/a while(it is省略) achieving a 32% reduction in overall energy consumption.

备注:现在分词 achieving 逻辑主语为 it，而且 it 指代介词 during 宾语,即 the Petrochemical PTA plant upgrade。
