废白土中油分回收及废白土的综合利用
|
摘要
在使用活性白土精制石油或动植物油的过程中会产生大量含油废白土,这些废白土如果能得到有效处理,不仅可以减少环境污染,而且可以促进资源的合理利用,给企业带来经济效益。总结了近年来废白土处理的几种方法,指出将废白土中的油分完全回收,恢复白土的孔道和活性,再生白土能够重复使用,从而使紧缺的白土资源得以保护和循环利用,实现可持续发展。
A lot of waste clay are produced from petroleum or animal and plant oil refining process. If waste clay can be treated effectively,not only the environmental pollution can be reduced,but also the utilization rate of resources can be promoted,and it can be good for enterprises. Several methods of treating waste clay in recent years were summarized in this article. It is pointed out that the oil in the waste clay can be fully recovered,the pore passage and activity of the clay can be restored,and the regenerated clay can be reused,so that the scarce clay resources can be protected and recycled,and the sustainable development can be achieved.
