无机膜应用于废润滑油再生

Regeneration of used lube oils with inorganic membranes

废润滑油污染对环境的潜在危害正日益显现,传统的废润滑油再生方法产生大量的酸性淤泥,造成二次污染,故提出膜分离应用于废润滑油再生的新思路,根据废油的特点来选取合适的膜来处理废润滑油,并利用降低油液黏度和压力膜过程来提高膜的渗透通量,使膜的渗透通量明显增加。

The potential hazards of pollution by used lube oils is generally showed up. The traditional way of used lube oils＇ regeneration produces numerous acidity mud, which can＇ t be compatible with the environment. We work out the new method to regenerate used lube oils with membranes for seperation, chose the right membranes to regenerate the used lube oils. With pressure membrane processes to increase the permeability of the membranes, the permeability of the membranes increased obviously.
