Is Fresh Water the Unique Water Supply Resource in Crude Oil Refinery?

摘要

The traditional concept of water supply resource in crude oil refinery was based on the fresh water, which could result in the low-efficiency water utilization in the water-stress condition. To solve the problem, the expanded concept of water supply resource was presented according to the crude oil refinery plant's water supply system analysis. The possibility of the water resources recycle was analyzed from the view of available resource according to the expanded concept. It provided an effective guide for water conservation and wastewater reduction in the crude oil refinery. And also, it provided the theoretical basis to accomplish zero wastewater discharge for petrochemical industry in the near future.
