Innovative Oil-Water Separation Technology for Oil Storage Facilities
In the routine operations of oil storage facilities, oil-water separation is a critical step for efficient operation and safety management. Oil-water separation specifically refers to the process of effectively separating water, which settles at the bottom of storage tanks, from crude oil during the processes of oil extraction, transportation, storage, and refining. The goal is to thoroughly remove the accumulated water at the bottom of the tank, ensuring the stability of crude oil quality and the safe and smooth operation of the storage facilities.
Implementing efficient oil-water separation can significantly reduce the concentration of pollutants such as oil and suspended solids in wastewater, thus mitigating the negative environmental impact. Meanwhile, the separated water can be reused as a resource or discharged after treatment to meet discharge standards, contributing to water conservation and promoting sustainable environmental management.
With increasingly stringent environmental regulations and the public's growing expectations for improved environmental quality, traditional water treatment methods in oil storage facilities are gradually becoming inadequate. As a result, an innovative oil-water separation treatment technology has emerged. This technology, with its high efficiency, environmental friendliness, and economic benefits, is leading the innovation in water treatment for oil storage facilities.
1. Overview of the Technical Process
The core of this process lies in the integration of two devices: CDFU (Cyclonic Dissolved Gas Flotation Unit) and High Efficiency Coalescing Pressure Degreaser.
The process begins with wastewater from the tank area entering the water separation buffer tank, where initial oil phase and suspended solids separation is achieved through gravity sedimentation. The wastewater is then directed into a coalescing oil separator, which uses unique coalescing filter materials and structural design to effectively capture and aggregate fine oil droplets smaller than 10 microns, significantly accelerating the oil-water separation process with a treatment efficiency of over 99%.
The effluent, after treatment by the High Efficiency Coalescing Pressure Degreaser, enters the CDFU (Cyclonic Dissolved Gas Flotation Unit). The CDFU generates a large number of ultra-micro bubbles that efficiently and quickly remove free oil, emulsified oil, and suspended solids from the water. These ultra-micro bubbles have strong adsorption capabilities, which enable the emulsified oil to break due to surface tension and remove oil contamination attached to suspended solids. This further reduces the oil and suspended solids content in the treated water, enhancing the system's ability to handle water quality fluctuations and ensuring the final effluent meets treatment and discharge standards.
2. Advantages of the Technology
·Exceptional Treatment Efficiency: The solution uses advanced technologies and equipment, efficiently removing various pollutants from wastewater, with a treatment efficiency of over 90%.
·Space-Saving: The modular and compact design greatly reduces the space required for the entire system, saving valuable land resources.
·Minimal Chemical Usage: The process requires little or no chemical additives, reducing sludge generation and subsequent treatment costs.
·Strong Resistance to Fluctuations: The system has good resistance to shock loads and can adapt to a wide range of water quality fluctuations, ensuring stable effluent quality.
·Low Overall Costs: Due to the simplified process flow and streamlined equipment, the system's investment, operational, and maintenance costs are significantly reduced.
In conclusion, this innovative oil-water separation process for oil storage facilities offers a new solution and development path for the industry, with its high efficiency, environmental sustainability, and cost-effectiveness.
